Announcing SQL Server on Linux

It’s been an incredible year for the data business at Microsoft and an incredible year for data across the industry. This Thursday at our Data Driven event in New York, we will kick off a wave of launch activities for SQL Server 2016 with general availability later this year. This is the most significant release of SQL Server that we have ever done, and brings with it some fantastic new capabilities. SQL Server 2016 delivers:

    Groundbreaking security encryption capabilities that enable data to always be encrypted at rest, in motion and in-memory to deliver maximum security protection
    In-memory database support for every workload with performance increases up to 30-100x
    Incredible Data Warehousing performance with the #1, #2 and #3 TPC-H 10 Terabyte benchmarks for non-clustered performance, and as of March 7, the #1 SAP SD Two-Tier performance benchmark on Windows1
    Business Intelligence for every employee on every device – including new mobile BI support for iOS, Android and Windows Phone devices
    Advanced analytics using our new R support that enables customers to do real-time predictive analytics on both operational and analytic data
    Unique cloud capabilities that enable customers to deploy hybrid architectures that partition data workloads across on-premises and cloud based systems to save costs and increase agility

These improvements, and many more, are all built into SQL Server and bring you not just a new database but a complete platform for data management, business analytics and intelligent apps – one that can be used in a consistent way across both on-premises and the cloud. In fact, over the last year we’ve been using the SQL Server 2016 code-base to run in production more than 1.4 million SQL Databases in the cloud using our Azure SQL Database as a Service offering, and this real-world experience has made SQL Server 2016 an incredibly robust and battle-hardened data platform.

Gartner recently named Microsoft as leading the industry in their Magic Quadrant for Operational Database Management Systems in both execution and vision. We’re also a leader in Gartner’s Magic Quadrant for Data Warehouse and Data Management Solutions for Analytics, and Magic Quadrant for Business Intelligence and Analytics Platforms, as well as leading in vision in the Magic Quadrant for Advanced Analytics Platforms.

Extending SQL Server to Also Now Run on Linux

Today I’m excited to announce our plans to bring SQL Server to Linux as well. This will enable SQL Server to deliver a consistent data platform across Windows Server and Linux, as well as on-premises and cloud. We are bringing the core relational database capabilities to preview today, and are targeting availability in mid-2017.

SQL Server on Linux will provide customers with even more flexibility in their data solution. One with mission-critical performance, industry-leading TCO, best-in-class security, and hybrid cloud innovations – like Stretch Database which lets customers access their data on-premises and in the cloud whenever they want at low cost – all built in.

“This is an enormously important decision for Microsoft, allowing it to offer its well-known and trusted database to an expanded set of customers”, said Al Gillen, group vice president, enterprise infrastructure, at IDC. “By taking this key product to Linux Microsoft is proving its commitment to being a cross platform solution provider. This gives customers choice and reduces the concerns for lock-in. We would expect this will also accelerate the overall adoption of SQL Server.”

“SQL Server’s proven enterprise experience and capabilities offer a valuable asset to enterprise Linux customers around the world,” said Paul Cormier, President, Products and Technologies, Red Hat. “We believe our customers will welcome this news and are happy to see Microsoft further increasing its investment in Linux. As we build upon our deep hybrid cloud partnership, spanning not only Linux, but also middleware, and PaaS, we’re excited to now extend that collaboration to SQL Server on Red Hat Enterprise Linux, bringing enterprise customers increased database choice.”

“We are delighted to be working with Microsoft as it brings SQL Server to Linux,” said Mark Shuttleworth, founder of Canonical. “Customers are already taking advantage of Azure Data Lake services on Ubuntu, and now developers will be able to build modern applications that utilize SQL Server’s enterprise capabilities.”

Bringing SQL Server to Linux is another way we are making our products and new innovations more accessible to a broader set of users and meeting them where they are. Just last week, we announced our agreement to acquire Xamarin. Recently, we also announced Microsoft R Server , our technologies based on our acquisition of Revolution Analytics, with support for Hadoop and Teradata.

Microsoft expands Cortana support, features in new Windows 10 'Redstone' build

Cortana's language support is expanding with this test build to include Spanish (Mexico), Portuguese (Brazil) and French Canadian. Cortana also is now able to save new reminder information, such as the name of a book and to-do items without specific due dates (like "remind me to wash the car").
Today's new Redstone 14279 test build also provides a merged logon experience, combining the lock screen background and the logon screen background into just one background. For those with custom lock screen backgrounds, the lock screen will now be used for both the lock screen and logon screen.

Build 14279 also includes fixes and known issues, as do all Insider builds. Among the fixes are remedies to the situation that caused the Edge browser and Cortana to crash for users with roaming profiles. Cortana also will no longer show reminders that have been completed. Microsoft also fixed issues causing certain drivers from Windows Update to cause some PCs to bluescreen, according to today's blog post.

In the known issues area, Microsoft is looking into an issue I've heard several users report: Their Surface Pro 3, Pro 4 and Surface Book devices can freeze or hang and prevent inputs including typing and touch from registering. Right now, the workaround is to hold the power button to force a hard reboot.

Users who have Kaspersky Anti-Virus, Internet Security or the Kaspersky Total Security Suite installed may also experience problems, which Microsoft and Kaspersky are working to fix.

Microsoft released a number of additional Windows 10 updates earlier this week for PC users, Windows 10 Mobile Insider testers and for Windows 10 IoT testers.

How to remove unwanted Apps from Windows 10

Windows 10 has many new and interesting features. Previous versions of Windows required the Control Panel to uninstall a desktop program. You can now use the Start menu or the settings app to uninstall unnecessary Apps. Whenever we want to remove unnecessary apps installed in our system, we move to the Control Panel but Windows 10 provides an alternative for removing apps directly from the Apps and features tab in the system section.
The following is the procedure to show how to remove unnecessary apps from Windows 10.
There are the following two ways to remove unnecessary apps:

1. With the Start Menu
2. With Setting App

With the Start Menu

The simplest way to remove apps is from the Start Screen. Press the Windows key on your keyboard or click the icon on the system's screen. At the Start Screen, go to the app that you want to remove and click the right button of your mouse or track pad and look at the lower-right corner, the third option will be uninstall, click on it. Some apps can't be removed (like Notepad), so you might not see the uninstall option.

 

 

 

Figure: Start Menu

 

With Setting App

Step 1

 

At first click on the Windows icon and the Settings option will open the Settings tab.

 

Figure: Settings

Step 2

In the Settings tab there is a System icon. Click on it.

 

Figure: System category symbol

Step 3

After clicking on the system category icon a new window of the system will be shown on the screen. On the left side bar you can see many options, click on Apps and features.

 

 

Figure: Apps and features window

 

Step 4

 

This will open the Apps and features tab. In this tab you can look for for any app. All you must do is to type its name and it will appear on the screen by choosing the first option. You can also sort various apps by their name, size and date using the second option.

 

 

Figure: Search Sort and Filter the Apps

Step 5

Now, scroll down to the bottom to see all the apps running in your system. You can directly uninstall these apps just by clicking on them and then pressing Uninstall. The apps in your system by default cannot be uninstalled.

 

 

Figure: Uninstall the apps in the system window

This is the easiest way to remove unnecessary apps from Windows 10 and boost your system's speed.

New study shows more people love Windows 10 than hate it

We're closing in on a month since the official launch of Windows 10. Millions of people have had a good amount of time to react to it, and it looks like overall impressions are positive. According to a study done by Brandwatch, which measured the response to Windows 10 on social media, the number of people who love Windows 10 far outnumbers those who hate it.
In all, 92% of responses have been positive, but Brandwatch does note that hostility is growing slightly, with 100 people expressing negative reactions for every 500 the profess a positive experience.


BrandWatch also took a look at which features were the most popular according to positive and negative mentions. Cortana is in the lead, with just over 80% of people expressing love for the digital assistant. Following behind Cortana (in order) are Edge, Xbox integration, Start Menu, Multiple Desktops, Action Center, and the taskbar.
At the bottom of the list is the Office Suite, with right around 40% of people in the study expressing a positive experience.

Keep in mind that this study comes from a relatively small sample size of just 7,000 persons, and is by no means definitive given there are many millions of Windows 10 users out in the wild now. However, the study does provide an interesting look at how Windows 10's features are doing, as well as the OS overall.

Leaked document reveals Office 2016 release date

Microsoft Office 2016

Microsoft's internal memo to employees has revealed that the company will be launching Office 2016 on September 22.
Last month, Microsoft launched the Mac version of Office 2016 leaving Windows users waiting for their turn. Now it seems the productivity suite is almost ready to ship as the company is preparing to launch it in a month's time.

According to a leaked memo acquired by WinFuture.de, the company has asked its employees to start using the public preview of Office 2016 and keep track of readiness, training and marketing material related to the product prior to the release on the 22nd of September.
Various applications that will be part of the release include Word, Excel, PowerPoint, OneNote, Outlook, Skype for Business, Project, Visio and Publisher, while updates to Office 365 and on-premise servers such as SharePoint Server will be made available later in the second quarter.
Office 2016 is expected to retail at a starting price of about €130 for the basic Home and Student version. We'll know more about it after Microsoft officially makes an announcement next month.

Windows 10 vs. Windows 8.1 vs. Windows 7 Performance

Three years ago we were benchmarking Microsoft's then latest operating system, Windows 8. At the time we were keen to make sure Windows 8 performed as well as Windows 7, which was a huge upgrade from 2006's Windows Vista.

In the end, we determined that Windows 8 was on par with 7 and at times a fraction faster, leading us to this conclusion in our performance review:

"Looking beyond benchmarks, Windows 8 appears more polished than Windows 7, even if you plan to live on the desktop and aren't too fond of the Start screen, general usage is smoother and appears to be faster on Windows 8, which I found most noticeable on our somewhat underpowered Athlon II X4 system. If anything, it's a great start. Now the Metro/Modern style will have to prove itself as a cross-platform OS that marries desktop, laptop and tablet PCs."

It's obvious now that the 'Metro' Start screen was an epic failure and in my opinion it was the only real issue with Windows 8, as I thoroughly enjoyed using the operating system with Classic Shellinstalled.

Fortunately, Microsoft learned from its mistakes and addressed some of Windows 8's shortcomings in Windows 10, which we believe is the best version yet, if only for its improved looks and functionality across devices and form factors.

After running the beta for months, I installed Windows 10 on launch day with the impression that it was relatively fast and stable, though it remained to be seen precisely how fast it was compared to Windows 8.1 and the beloved Windows 7.

That's what we plan to find out today as we test various aspects of the operating system including boot up and shutdown times, file copying, encoding, browsing, gaming and some synthetic benchmarks.

Test System Specs

All three operating systems were tested using a fresh install with all the updates applied and then our test software installed. The exact same hardware was used for each configuration with the only difference being the OS used.

• Intel Core i5-4670K (3.4GHz - 3.8GHz)
• Asrock Z97 Extreme6
• 8GB DDR3-2400 RAM
• Nvidia GeForce GTX 980
• Crucial MX200 1TB
• SilverStone Essential Gold 750w
• Windows 7, Windows 8.1, Windows 10 Pro 64-bit

Boot, Sleep & Hibernate Performance

Using BootRacer we measured the time it took for Windows to boot. Windows 8.1 delivered the best result taking just four seconds opposed to six seconds on Windows 10, from the Windows logo to usable desktop.

Manually measuring boot time with a stopwatch delivered similar results, though in realistic terms I struggled to find real differences, with the three operating systems just one or two seconds apart from each other on a fresh install.

Surely these results will vary depending on hardware used, configuration and state of the operating system after months of use, patching and third party apps taking its inevitable toll. We know our hardware was identical for all three OS configurations, so with this setup Windows 10 does appear slightly slower at booting.

Here we measured the time it takes for the system to wake up from sleep. The test stops the moment the desktop is loaded and we induced sleep with a custom shortcut.

Windows 7 takes quite long to wake from sleep -- 17 seconds on average. Windows 8.1 is considerably faster taking just 12 seconds, though Windows 10 was able to improve on this shaving off an additional 2 seconds.

Editor's note (Update): Many readers have pointed out how slow these wake up from sleep times are compared to your laptop where either version wakes up almost instantaneously. The reason is that we ran all tests in a desktop PC, where Windows defaults toHybrid Sleep. Hybrid sleep is a combination of sleep and hibernate meant to prevent users from losing work in case of a power failure.

The wake up from hibernation results are similar to wake from sleep. Here Windows 10 took just 21 seconds, while Windows 8.1 was slightly slower taking 23 seconds and then Windows 7 at 27 seconds.

It's now possible to run Android apps on Windows 10 Mobile

For many months, we had been reporting that Microsoft was considering bringing Android apps to the Windows Phone ecosystem. And today, you can finally experience Android Apps on Windows 10 Mobile but be warned, it's not an easy process and can force you to re-flash your device, so move ahead cautiously.

In the image at the top of this post, one user has Periscope up and running on his Lumia 920.

For starters, not all devices are supported at this time and make sure you are running the latest version of Windows 10 Mobile. Knowing you could damage your device, if you want to try out Android apps, read below.

Here is the list of supported devices:

• Nokia Lumia 920
• Nokia Lumia 925
• Nokia Lumia 929 / Verizon Icon
• Nokia Lumia 830
• Nokia Lumia 930
• Nokia Lumia 1520
• Nokia Lumia 635 (1GB RAM variant)
• Nokia Lumia 730
• Nokia Lumia 820
• Nokia Lumia 435
• Nokia Lumia 928

If you have one of the above devices, here’s how to install the apps:

• Download Android SDK’s ADB and wconnect tool from here.
• Extract the files in the folder and Open the folder wconnect,then installIpOverUsbInstaller.msi and vcredist_x86.exe
• Open the Windows 10 Mobile’s Settings page ->Update & Security > For Developers and enable Developers Mode, as well as Device Discovery
• Open the extracted wconnect folder, open an elevated command prompt (Shift+right click > Open command window here)
• Then you’ll need to connect to the phone — (USB method is recommended):
• To Connect using USB, type wconnect.exe usb and hit enter
• Then it’ll ask for the pairing code, enter the code and hit enter
• Then navigate to the extracted adb folder and open an elevated command prompt
• To make sure that your device is connected, type adb devices and hit enter to show the list of devices that are connected
• Lastly, place the APK file that you want to install on the same directory (adb folder) and type in adb install APKNAME.apk (replace APKNAME with the APK file’s name)
• That's it, then you can install the APKs.

Couple of things to keep in mind, obtaining APKs may not be legal in your area, so keep that in mind, also, this is highly experimental at this time and many users are reporting that this is causing their devices to be frozen and forcing a complete re-flash of the device. Do not try this on anything other than a development device.

But what this will allow you to run some Android apps on your phone but at this time, if they depend on a Google service, not surprisingly, they will not be functional on a Windows 10 Mobile device. But, seeing as users are already getting some apps up and running, shows that for Android developers, bringing their apps over to Windows 10 Mobile is going to be a trivial task.

While this move may sound like Microsoft is giving up on native app development for Windows 10 Mobile, it does solve the bigger issue of not having enough high quality apps on its mobile devices.

Enabling GodMode for Windows 10

 

Just a quick-hit tip here. Those that are familiar with gaming know that there's almost always a tweak available to find that will enable god-like powers in games. These tweaks give you things like unlimited lives, indestructibility, and infinite powers. In reality, it's a cheat. But, who hasn't enjoyed it and used it to learn how to beat the toughest levels of gameplay?

For those Windows 10 testers hungry to have similar god-like powers, Windows 10 has its own GodMode. GodMode for Windows 10 gives you access to 262 new god-like powers. And, while it doesn't give you unlimited lives or save you from bluescreens, it does expose some additional features and tools to play with.

 How to enable it

Enabling GodMode is pretty simple. You simply create a new folder (can be created anywhere, but I suggest putting it on the Windows 10 Desktop so it's easy to locate), and give the new folder an intricately specific name.

1.       Create a New Folder on the desktop…

2.       Rename the folder to exactly this (copy and paste is best):

GodMode.{ED7BA470-8E54-465E-825C-99712043E01C}

Voila! Welcome to GodMode! Have fun with it.

I'll be digging through these and talking about some of the more unique and valuable ones. Stay tuned.

P.S. While I've written this tip is for Windows 10, it also works for other versions of Windows. Try it on the version you are using. Works great for Windows 8.1, which exposes 270 functions.

Windows 10 receives its second set of fixes with new cumulative update

It’s been rumored and arguably validated by many, that the Windows 10 July 29th release was essentially rushed. Journalists and observers have come up with a myriad of speculative reasons as to why Microsoft may have shifted from its recent tradition of shipping its OS in the fall to mid summer. The overwhelming theory revolves around appeasing PC OEMs during ‘Back to School’ season.

Whatever the reason, many Windows users are now running into issues regarding the semi-incomplete nature of Windows 10 currently. Back during the Windows 10 reveal, Microsoft noted that the OS would be a constant 'work in progress'. Microsoft is continuing that trend today with a Service Release 1 (SR1) update. A cumulative update (KB3081424) for Windows 10 is now live and is a collection of fixes and under-the-hood improvements which are said to improve overall performance. However, the main install is intended to address a multitude of post-release issues Windows users are running into.

​Today's cumulative update is not the first update for Windows 10. On July 29th, Microsoft released a similar patch which included over 1GB of improvements for new users upgrading from Windows 7 and Windows 8.1
