The latest update from Panos Panay on Twitter is including New and redesigned Snipping tool inside Windows 11. From the shared video, we can see that it includes modern Windows 11 UI redesign and it looks and feels like a part of Windows 11. More things that can be seen from the shared video is that it looks like the new snipping tool is a merged version of the old with snip & sketch. It is good to see that it is still possible to capture screen with easier way natively inside Windows 11 but some more functionality would be more welcome I guess. Users were asking for added functions for a long time like adding simple text for example but from shared video, no new features were presented so for some users 3^rd party solutions will still be the way to go. The new and redesigned Snipping tool will roll out with the next update and we will see then about all new features inside it firsthand. Until then, take care.

Virtual Reality is slowly becoming standard in gaming. More and more affordable headsets are coming out lowering entry prices and making them affordable for all. But in a sea of new VR headsets, it is important to at least purchase a decent one that will perform nicely and hopefully last longer. Therefore in today’s article, we will address some of the best options currently available on the market,

Oculus Quest 2

With its Rift model, Oculus set itself as a big player in VR. Now the company is slowly bowing out of the dedicated, tethered VR headset with its latest Quest 2 designed to primarily be a standalone headset. In case you do not know, tethered headset means that the headset itself is connected to your PC and is using its power to drive your VR experience. Now technical specifications of Quest 2 are pretty OK and it can drive stuff pretty decently and if you want you can purchase the dedicated cable to connect it to your PC for the full experience of games requiring more capable hardware. Oculus Quest 2 is the cheapest headset on this list and with its stable performance, is highly recommended.

Valve Index VR

Although the headset itself is nothing revolutionary or special its controllers are. They can track individual finger movements, making games (that take advantage of them) much more immersive than the standard trigger grips on other controllers. The Index's higher refresh rate makes for smoother action, as well, which is another nice bonus. If you already have an HTC Vive or Vive Cosmos Elite, and their base stations (not the regular Cosmos), you can buy only the controllers.

Sony PlayStation VR

The PlayStation VR is compelling thanks to Sony backing its development, plus the PlayStation 4's affordability and availability compared with gaming PCs. All you need is the headset, a PlayStation 4, and a PlayStation Camera (now included with most PlayStation VR bundles). Not really the best of the bunch but still one of the top ones for console gaming. Sony is working on a new PlayStation VR system for the PlayStation 5, with redesigned controllers. The new headset hasn't been revealed yet, but the company has released a preview of the new controllers.

HP Reverb G2 VR

HP headset is one which you get if you want the best image quality in VR headset, sadly controllers did not follow the same quality of headset itself. But this is still a pretty decent headset overall and worth the purchase.

HTC Vive Cosmos

HTC's Vive Cosmos is the upgraded version of the Vive. It features a higher resolution and replaces the external base stations with outward-facing cameras for motion tracking. It's a comprehensive package for whole-room VR. HTC recently released the Vive Pro 2, a high-end VR headset targeting both enterprise users and consumers. This new headset features a 2,448-by-2,448 resolution display for each eye, making it the highest-resolution headset currently available. It's also more expensive than the Cosmos Elite. Sadly one thing that is bringing this headset down is the price.

Just what is a PST File?

PST file is the acronym for Private Storage Table. It is a proprietary file structure utilized in the ms-outlook program shop and to preserve attachments as well as e-mails, notifications, scheduled calendar events, and even more. This structure can also be called a Personal Folder File. The storage limit or the size varies today with respect to the Outlook version you've got installed. The PST file size limit depends on the edition you have installed. Outlook 2002 and earlier versions have a memory limitation of 2GB while later versions such as Outlook 2013 have up to 50GB memory limit.

Error Causes

You will be amazed to discover there is not a single cause behind this problem. The File can be damaged due to a number of reasons including:

When you try to open your Google Chrome browser and it starts to connect to the internet but suddenly, your Windows 10 computer crashes along with a Blue Screen error that says, “MEMORY_MANAGEMENT”, then read on as this post will guide you in fixing the problem. This kind of BSOD error occurs when Google Chrome requests more memory or when it tries to access the network and demand is raised for more memory, the memory management program fails. To fix the problem, here are some possible solutions you might want to try. Follow them thoroughly.

Option 1 – Use the Driver Verifier Manager

The Driver Verifier Manager is another tool in Windows that could help you fix driver-related issues. And since the MEMORY_MANAGEMENT Blue Screen error concerns Google Chrome and an internet connection, the root cause of the problem might have something to do with the Network driver and to verify that, you can use the Driver Verifier Manager:

• Type in the keyword “Verifier” in the Cortana search box to search for Verifier in Windows 10.
• After that, select the option “Create custom settings”.
• Make sure that you have checked everything except the options “DDI compliance checking” and “Randomized low resources simulation”.
• Next, select the option “Select driver names from a list” option.
• Afterward, you have to select all the drivers from any unofficial or third-party provider. To simply put it, you have to select all the drivers that are not supplied by Microsoft.
• Then click on the Finish button.
• Open Command Prompt as administrator and execute this command – verifier /querysettings
• The command you just executed will display the Driver Verifier settings so if you see any of the flags enabled boot your Windows 10 PC into Safe Mode.
• Open the Command Prompt as admin again and run this command – verifier /reset
• The command will reset the Driver Verifier. Once the process is done, restart your PC and check.

Option 2 – Try updating the Network drivers

• Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
• Then right-click on each one of the Network drivers and update them all.
• Restart your PC and see if it helped in fixing the MEMORY_MANAGEMENT BSOD error.

Option 3 – Try disabling Hardware Acceleration

You might want to disable Hardware Acceleration system-wide or for a particular program like Google Chrome and see if it resolves the MEMORY_MANAGEMENT error

Option 4 – Run the Memory Diagnostic Tool to check for Memory leaks

• Tap the Win + R keys to open Run and type exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:
  • Restart now and check for problems (Recommended)
  • Check for problems the next time I start my computer
• Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Note: After you select the option, your PC will restart and check for memory-based issues. If it finds any issues, it will automatically fix them and if there’s no issue found, then it’s most likely not a memory-based issue so you should try the other options given below.

Option 5 – Perform a System Restore

Performing System Restore might help you in fixing the SYNTP.SYS Blue Screen error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 6 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like MEMORY_MANAGEMENT. It can be found in the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Even with the new Groove Music in Windows 10, a lot of users still prefer to use the old Windows Media Player. This isn’t surprising since Windows Media Player still remains to be one of the best players you can find. However, that does not mean that it is without flaws as it could still encounter some issues from time to time. One of the issues you might encounter when using the Windows Media Player is when you try to burn DVDs or CDs but end up failing due to an error that pops up that says, Windows Media Player cannot detect the length of the file. At the time of writing, it isn’t clear yet what the real cause of the error is. However, there are several fixes that are provided in this post for you to check out so you can resolve the problem. You can try to get rid of any unsupported files from the burning list or you could also try running the Windows Media Player troubleshooters. Aside from that, you could also try to drag and drop music or change the burning speed. For more details, refer to the following options.

Option 1 – Get rid of the unsupported files from the burning list

You must get rid of the unsupported files from the list of files to burn. This list can be found on the right-hand side of the Windows Media Player. One of the indications that a file is causing problems is when there is a white cross in a red circle next to the file. You can simply click on that icon to remove the file from the burning list. Once you’ve gotten rid of all the unsupported files, try to burn your files to the CD or disk once more.

Option 2 – Try running the Windows Media Player troubleshooters

The next thing you can do to fix the error is to run the built-in troubleshooters for the Windows Media Player. Windows 10 actually comes pre-packed with three troubleshooters designed for Windows Media Player. They can help in fixing the “Windows Media Player cannot detect the length of the file” error. To run these troubleshooters, simply tap the Win + R keys to open the Run dialog box and type “msdt.exe -id WindowsMediaPlayerConfigurationDiagnostic” for the Windows Media Player Settings troubleshooter or type “msdt.exe -id WindowsMediaPlayerLibraryDiagnostic” for the Windows Media Player Library troubleshooter, or type “msdt.exe -id WindowsMediaPlayerDVDDiagnostic” for the Windows Media Player DVD troubleshooter.

Option 3 – Try to drag and drop music

Another thing you can check out is to drag and drop all the tracks into the Windows Media Player before you burn them. All you have to do is open the folder where the tracks are located and highlight all of them and then drag them to the Windows Media Player. It should now be able to detect the length of each one of the tracks without any errors.

Option 4 – Try to change the burning speed

Since the burning speed is set to fastest by default, you can try to change the burning speed to resolve the problem. Just open the Options window and then go to the Burn tab. From there, select either Medium or Slow burning speed and save the changes made. Now try to burn your files to the CD or disk once again.

What Is 0x000000D1 Error?

Error code 0x000000D1 is a serious error that is displayed when Windows automatically shuts down to protect the system against further damage.

Usually, when this error occurs, the message displayed to the users states something like STOP 0x000000D1 DRIVER_IRQL_NOT_LESS_OR_EQUAL.

Solution

What Causes 0x000000D1 Error?

Usually, the STOP 0x000000D1 error code is caused by issues like incompatibilities, third-party drivers, driver conflicts, outdated drivers, malicious drivers, and other related problems.

Speaking technically, the message displayed to the user actually means that the kernel-mode driver has tried to gain access to memory at an unreasonably high process IRQL.

If left unfixed, STOP 0x000000D1 error can become quite serious. Increased frequency of occurrence may not only lead to data loss but can cause system corruption as well. That’s why it is crucial to fix it and to resolve the underlying issues causing it as soon as possible.

Further Information and Manual Repair

There are different ways of quickly fixing this error, some of which are briefly listed below as follows.

• The solution advised for advanced users is to start the system and log on to it as the administrator. Then do to Start button. Click on All Programs -> Accessories-> System Tools->  System Restore. Here you will find the option, “Restore my computer to an earlier time”. Click on it and select ‘Next’. A list of restore points will appear in front of you. Select the latest restore point and then click on ‘Next’. The confirmation window will appear again. Click on the Next button again. Restart your computer. Congratulations, you have successfully restored your computer.

Once that happens, choose the Fix/Repair button. Your scan will be completed. The error will be removed. You can then restart your computer again to ensure the error is no longer displayed.

Some other suggestions to keep your computer from encountering these problems in the future are outlined below.

• Update all your drivers. Obsolete or old hardware or software drivers may also trigger this STOP 0x000000D1 error.
• If you have recently installed or modified a driver or hardware and the error has occurred afterward, it is highly likely that the installation or modification has caused it. Revert back to the original settings to steer clear of this driver in the future.

A PC that turns on by itself every so often can get quite annoying. Many users have faced this problem countless times. There are lots of possible reasons why your Windows 10 PC turns on by itself, wakes up from sleep, standby, or even when it’s shut down. To find out what exactly woke your computer, simply open Command Prompt as admin and type the following command:

powercfg –lastwake

Once you enter the command given above, it will show you the last device that woke your PC up. After that, you need to type in the next command:

powercfg –devicequery wake_armed

After entering the command, it will show you a list of all the devices that could wake your PC up. The goal in running these commands is to understand the reason what’s really causing your PC to turn on and see the reason is on the hardware level or not. Here are a couple of options you can try if your Windows 10 PC turns on by itself.

Option 1 – Try disabling Fast Startup

As you know, Windows 10 comes with a mode called Fast Startup which does not turn off the computer in the usual manner. This mode keeps your computer in a mixed state so that when you turn it on again, it will be a lot faster. However, as useful as this feature appear to be, some security experts find this an issue, for numerous reasons – for one, it can turn on your Windows 10 PC by itself. Thus, you need to disable this feature to fix the problem.

Option 2 – You need to stop the Task Scheduler from waking up your computer

There are times when the issue has something more to do with the software than hardware. It could be that you are using a Scheduled Task to get some work done on your computer at a particular time of the day or many times a day. That’s why if you really are using Task Scheduler, you need to change the Power settings of Windows to make sure that it ignores those tasks rather than deleting them instead when your computer is either on Hybrid or Standby mode.

• Open the Power Options and then click on “Change Plan Settings”.
• After that, make sure to choose the correct power plan and then select the “Change advanced power settings” option.
• Next, look for the Sleep tree and expand it to view the “Allow Wake Timers” option and then disable it. Disabling this option will make sure that none of the program that could wake your PC up when it’s either on shutdown or sleep mode. However, this only applies to laptops.

Option 3 – Try to disable Automatic Restart

There are instances when the computer crashes and the system restarts itself. This is actually by design – when your computer has been left on standby, the computer will restart and if the program repeats, it will keep on waking your PC up.

• In the Search bar, type in “system”.
• Once it appears from the search results, click on it.
• Next, select Advanced system settings on the left side and then go to the Advanced tab.
• From there, click on Settings under Startup and Recovery.
• Then unmark “Automatically Restart” and click on OK.

Option 4 – Adjust the Power Management option of both the Keyboard and Mouse

As you know, two of the culprits in waking your PC up are the keyboard and the mouse. If they’re slightly moved or hit, your PC turns on. To prevent these two from waking your computer up, you need to make some adjustments to their power management option since they have one. You can disable this option to ensure that they won’t wake your PC up unless you really want it to.

• Tap the Win + X keys and then tap M to open the Device Manager and list all the hardware on your computer. From there, select your keyboard or mouse.
• Next, right-click and then go to Properties and go to the Power Management tab.
• In this tab, uncheck the “Allow this device to wake the computer” box.

Note: Aside from the keyboard and mouse, if you are also using any gaming rig to play games on your computer, then you might have to disable their power options as well as they could also wake your computer. Just make sure that either the keyboard or the mouse has the ability to wake your computer up at the very least as it can be quite inconvenient to tap the Power button every time you want to turn on your computer.

Option 5 – Modify Wake On Lan

The Wake On Lan feature can bring back your computer online if it is connected to a network. This feature is useful especially when a computer wants to communicate or to send data or files to a network computer which should come online only when it’s requested. Wake On Lan is built into the hardware, i.e. network adapter so it is one of the possible reasons why your PC turns on by itself.

• Tap the Win + x keys then hit M to open the Device Manager and then under the Network adapters, look for the one that was listed above. Take note that you must not change anything with the ones that are listed as Miniport.
• Next, right-click and select Properties and then go to Power management and from there, uncheck the “Allow this device to wake up the computer” option. This will ensure that no PC on the network can ever wake your computer up.

Option 6 – Prevent any scheduled Windows Update and Automatic maintenance

It is also possible that the Windows Update has restarted your PC to complete the update. This depends on your active hours or a predefined schedule. AS you know Windows has a built-in Automatic Maintenance mode which wakes the computer up at the scheduled time and performs the system update. This could be one of the possible reasons why your computer turns on by itself. so to prevent any scheduled updates and maintenance, you can simply change the time for Automatic maintenance. How? Follow these steps:

• Open Settings then go to Windows Update and Security >Windows Update and select Active Hours.
• After that, type in “Automatic maintenance” in the search bar to change the time for Automatic maintenance.
• From there, you can adjust the timing or just uncheck the “Allow scheduled maintenance to wake up my computer at the scheduled time” box.
