While running your Windows 7/Windows Server 2008 R2, your system suddenly stops responding out of complete randomness and you see an error message popping up which says something like this:
The stop error 0x00000050 signifies that there’s a PAGE_FAULT_IN_NONPAGED_AREA problem. If you’ve seen this error on different occasions then you will find the parameters in the message to be varying. That is because they are dependent on your PC’s configuration. Not all Stop errors "0x00000050” occur due to a single issue.
However, the most common problem which is encountered which results in the stop error popping up is due to a pool corruption occurring in the Srvnet.sys file.
This issue might be caused because of software incompatibility or a defective physical memory which resulted in requests for data for a hardware driver or service which was not found in the memory.
If you find the error occurring after you’ve installed a new application or a device driver then you should access Safe Mode and uninstall, disable or remove that application or driver.
Further Information and Manual Repair
In order to fix this issue, you should try booting your computer to the “Last Known-Good Configuration” as listed during startup.
For this you have to follow the below-mentioned steps:
Start your system.
When you see the message which says “For Troubleshooting And Advanced Startup Options For Windows, Press F8” hit F8 and proceed.
Use the up and down arrow keys to highlight “Last Known-Good Configuration” and hit enter (This method will only work if your system boot was not successfully carried out ever since you made any specific changes).
When you are starting the computer, press F12 and proceed with the PSA/32 Bit Diagnostics.
Do the following so that a clean boot can be performed:
Go to the Start menu when the Windows 7 desktop shows up.
On the search bar, type “msconfig” and hit search.
Disable all the applications which are listed on the “Startup” tab.
Now head over to the “Services” tab and mark the option which reads "Hide all Microsoft Service".
Select the “Disable All Services” option.
Apply the changes by clicking on “Apply” then restart your PC. You should now check the performance of your computer. If you don’t see a BSOD then you start re-enabling all the Services and Startup applications one by one until you finally figure out which one is causing the BSOD to appear.

The Error Code 0xC1900208 – 0x4000C is an error that is caused by an installed application or program on your computer that is not compatible with Microsoft Windows 10. The incompatible application prevents you from being able to complete the upgrade to Microsoft Windows 10 and will continue to do so until the issue is resolved.
Common symptoms include:
You receive a dialog box displaying Error Code 0xC1900208 – 0x4000C
You are unable to successfully complete the Microsoft Windows 10 upgrade process.
Solution
Error Causes
Error Code 0xC1900208 – 0x4000C is caused by a non-compatible application or program that is currently installed on your computer, and is not allowing the Microsoft Windows 10 upgrade to finish the installation and update process.
The upgrade is stopped due to an incompatible app or program.
Out of date or no longer supported software can cause this error to occur.
Device drivers that are not up to date or no longer compatible.
The computer might pick up malware along the way and might be preventing the upgrade. If error code 0xC1900208 – 0x4000C is not rectified, you’ll not be able to proceed with your Windows 10 upgrade.
Further Information and Manual Repair
The good news is, error code 0xC1900208 – 0x4000C is a relatively common problem that is usually easily fixed by the user at home, though it can be a little time-consuming. To elude this time-consuming process, use a powerful tool to rectify the issue in no time (TSC). Before making any attempts to repair this error, ensure to perform a compatibility test.
Check the compatibility of applications and programs installed on your computer to locate and remove, or fix the one that is incompatible. (Don't stop at the first one you find, there could be multiple incompatibility issues.)
Check to ensure all programs and software are not outdated or no longer supported, and remove or fix any outdated or unused, unnecessary programs or software. (This is also a great way to free up space and clean your computer up a bit.)
Check to ensure that all of your device drivers are current, up to date, and compatible with Microsoft Windows 10, and replace or update where necessary.
Method 1:
Use the get Microsoft Windows 10 application on your computer to check its compatibility, follow the steps below to run the check.
Look at the taskbar, to the right; you will see an icon for Microsoft Windows 10, right-click the icon. Locate the option in the menu to check the status of your upgrade. This will open an app for getting Microsoft Windows 10.
Next, you will see 3 lines on top of one another on the upper left side, this will open a drop-down menu, once you have this menu open, locate the option to check the compatibility of your computer.
Microsoft Windows will then run a check of your entire computer to check for compatibility with Microsoft Windows 10. Once it has finished its check, a pop-up window will display whether or not your computer will work with Microsoft Windows 10, and will also display a list of any hardware and software that are not compatible with the upgrade.
This may not catch everything and there may still be incompatible programs so the previous steps, though time-consuming may still be necessary.
Method 2:
Once the incompatible applications are discovered, use the control panel to remove/uninstall them. The steps are below:
Locate your computer’s Control Panel.
Choose the option that says “Programs”
From the options available, select the ‘Programs and Features’ link.
Locate the app in the queue or menu.
Right-click and choose the uninstall option.
… another option
You can also locate the app on the ‘app homepage’, right-click and choose the ‘uninstall’ option. If after following these steps the problem is still not corrected, download and install an automated tool for a quick fix.
If you were trying to open File Explorer but it suddenly stopped working and you encounter an error message that states, “An attempt was made to reference a token that does not exist”, read on as this post will guide you in fixing this problem. This problem was initially reported after the April Update and Microsoft was able to fix it right after correcting the build. However, this effort seems futile for some users as recently, some reported getting the same error when they try to open not just Windows File Explorer but also with utilities like Microsoft Management Console or MMC, Visual Studio, Task Manager, Printer, Recycle Bin, etc.
Two of the most likely causes of this error are a troublesome Windows Update and corrupted system files. Whatever the cause is, here are some suggestions you can follow to fix the “An attempt was made to reference a token that does not exist” error.
Option 1 – Try to re-register the problematic DLL file
You may have to re-register the ntdll.dll file using the regsvr32.exe before you can successfully install the program and fix the ntdll.dll file crash error. The Regsvr32 tool is a command-line utility that can be used to register and unregister OLE controls like DLL and ActiveX (OCX) control in the Windows operating system. Follow the steps below to use it.
Open Command Prompt as admin from the WinX menu.
Next, type the following commands in the elevated Command Prompt and hit Enter to execute the command. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.
exe /[DLL file]
exe [DLL file]
Note: Replace “[DLL file]” with the name of the DLL file that was pointed out in the error.
After you execute the given commands, you should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. After that, try to install the program again and see if it now works.
Option 2 – Replace the DLL file from a trusted source
First, you need to get the new DLL file from another computer with preferably the same file version number.
After that, you need to boot your PC into Safe Mode and navigate to the paths listed below and then replace the file using a USB drive or other external storage devices.
x86: This PC > C:/Windows/System32
x64: This PC > C:/Windows/SysWOW64
Next, type “cmd” in the Cortana search box and right-click on Command Prompt, and select “Run as administrator” to open it with administrator privileges.
Now type the “regsvr32 ntdll.dll” command and hit Enter.
Restart your PC and check if the error is now fixed.
Option 3 – Perform a System File Checker scan
The System File Checker or SFC scan could detect and automatically repair damaged system files that could be causing the “An attempt was made to reference a token that does not exist” error to pop up. SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.
Tap Win + R to launch Run.
Type in cmd in the field and tap Enter.
After opening Command Prompt, type in sfc /scannow and hit Enter.
The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:
Windows Resource Protection did not find any integrity violations.
Windows Resource Protection found corrupt files and successfully repaired them.
Windows Resource Protection found corrupt files but was unable to fix some of them.
Option 4 – Try reverting back to the previous build of Windows
This kind of error might have something to do with a Feature Update so you can try to revert your computer to a previous build of Windows 10 as it could help you fix the problem. In this case, it would better if you refrain from updating your Windows 10 computer until this problem is completely resolved by Microsoft.
If you suddenly encounter a Blue Screen error that points out to either the mfewfpk.sys and epfwwfp.sys files, then this post might help. Both of these files are created by third-party software. The mfewfpk.sys file is created by the McAfee security software while the epfwwfp.sys is created by the ESET Antivirus. These files are residual files and sometimes it blocks upgrading Windows 10.
Aside from blocking Windows 10 upgrade/update, these files can also cause a Blue Screen error after an upgrade which leaves your Windows 10 computer useless. When you get a Blue Screen error caused by any of these files, you will see an accompanying error message that states, “DRIVER IRQL NOT LESS OR EQUAL”. To fix this Blue Screen error, you can check out the suggestions laid out below but before you do that, you need to create a System Restore point first as it can help you undo any unwanted changes. In addition, make sure to also boot your computer into Safe Mode with Networking before you troubleshoot.
Option 1 – Try to remove the epfwwfp.sys file
You can try to remove the epfwwfp.sys file using Command Prompt. To do so, refer to the following steps:
Right-click on the Start button and click on Command Prompt (Admin) from the menu to open Command Prompt with admin privileges.
Next, type the following command and hit Enter to delete the epfwwfp.sys file:
DEL /F /S /Q /A “%systemroot%System32driversepfwwfp.sys”
After the scan is completed, restart your computer and see if it fixed the Blue Screen error.
Note: You can also use the ESET AV Remover tool to uninstall Eset security software to remove the epfwwfp.sys file.
Option 2 – Try to remove the mfewfpk.sys file
The same with the first option, you can remove the mfewfpk.sys file using CMD.
First, right-click on the Start button and click on Command Prompt (Admin) from the menu to open Command Prompt with admin privileges.
After, type the following command and hit Enter to delete the epfwwfp.sys file:
DEL /F /S /Q /A “%systemroot%System32driversmfewfpk.sys”
Once the scan is completed, restart your computer and see if it fixed the Stop error.
Note: You also have the option to remove the mfewfpk.sys file using McAfee Product Removal tool to uninstall the McAfee security software. All you have to do is download the McAfee Product Removal tool and run it and then follow the onscreen instructions to install it. Once it is installed, click on Next. After you select the radio button to agree to the terms of use, click on Next once again. Finally, restart your computer and check if it is able to resolve the problem or not.
Option 3 – Run the Blue Screen Troubleshooter
Troubleshooting Blue Screen of Death errors wouldn’t be complete without the Blue Screen troubleshooter. As you know, it is a built-in tool in Windows 10 that helps users in fixing BSOD errors. It can be found on 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.
Option 4 – Try running the DISM tool
You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the Blue Screen error. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.
Open the Command Prompt with admin privileges.
Then type in the following commands and make sure to hit Enter right after you type each one of them:
Dism /Online /Cleanup-Image /CheckHealth
Dism /Online /Cleanup-Image /ScanHealth
exe /Online /Cleanup-image /Restorehealth
Do not close the window if the process takes a while as it will probably take a few minutes to finish.

As of late, a number of users reported experiencing a problem where their Windows 10 computers get stuck on Airplane mode for some unknown reason. According to the affected users, they were unable to turn off the Airplane mode which means that their computers are also not able to connect to the internet. One of the possible reasons why this kind of issue occurs is that there could be a bug with the airplane mode or it could also be the doing of faulty network drivers or physical switch that’s turned on, and so on. If you are one of the few users who experience the same issue, then read on as this post will guide you on what to do if your Windows 10 computer gets stuck on Airplane mode.
There are a couple of suggestions you can check out to resolve the problem. You can try to check the status of the Radio Management service, flush the DNS cache or you could turn off the airplane mode via system settings. You could also update the network drivers or turn off the physical switch for airplane mode or make some adjustments in the Windows Registry. For more details, refer to each one of the suggestions provided below.
Option 1 – Try to check the Radio Management Service status
First, tap the Win + R keys to open the Run dialog box and type “services.msc” in the field, and hit Enter to open the Windows Services Manager.
Next, look for the Radio Management service and select Properties.
From there, change its Startup type to Disabled and click on the Apply and OK buttons to save the changes made.
Once done, restart your computer and check if you can now turn off the airplane mode.
Option 2 – Flush the DNS cache
You could also try to flush the DNS cache to fix the “ERR_ICAN_NAME_COLLISION” error. All you have to do is open Command Prompt as an administrator and then execute each one of the following commands sequentially to flush the DNS cache:
ipconfig/release
ipconfig/renew
ipconfig/flushdns
Option 3 – Try turning off the airplane mode via System settings
If flushing the DNS cache did not help in fixing the problem, then you might want to turn off airplane mode via system settings.
In the Windows Search bar, type “airplane mode”.
From the search results that appear, click on Airplane mode.
After that, a window will appear where you have to turn off the toggle button for Airplane mode.
Option 4 – Try to update, rollback or reinstall the Network adapter drivers
The next thing you can do to resolve the problem is to update the Network Adapter drivers by following these steps:
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 them.

Restart your PC and see if it helped in fixing the problem.
Note: If updating the network drivers didn’t help in fixing the problem, you can also try to roll back the very same drivers from their previous versions and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.
To reinstall the network adapter drivers, refer to these steps:
Open the Devices Manager from the Win X Menu.
Then locate the device drivers and right-click on them to open the Properties.
After that, switch to the Driver tab and click on the Uninstall Device button.
Follow the screen option to completely uninstall it.
Finally, restart your computer. It will just reinstall the device drivers automatically.
Option 5 – Try to turn off the physical switch for Airplane mode
If your computer has a physical switch to turn on or off the airplane mode, then you might want to check that switch if you have one. Chances are, it could be the reason why you’re unable to turn off Airplane mode on your computer.
Option 6 – Try to make some adjustments in the Registry
Tap the Win + R keys to launch the Run utility.
Then type “Regedit” in the field and hit Enter to open the Registry Editor.
Next, navigate to this registry path: HKEY_LOCAL_MACHINESystemCurrentControlSetControlClass

Exit the Registry Editor once done, and restart your computer.
Rstrui.exe is a service assigned to controlling system restore, it is considered an essential part of the Windows system and without it working you will not be able to perform a system restore operation.
Without system restore working you will not be able to "rewind" Windows into a working state if needed which can create in itself many new complications. Luckily we have working solutions for this specific problem, so get ready, and let's start.
SFC scan
Sfc scan is a built-in Windows tool that scans and repairs system corrupted and missing files. To run it open up the command prompt in administrator mode and type in it:
SFC /SCANNOW
then, let the whole process finish, do not interrupt it, and reboot after it is done.
DISM scan
Similar to SFC scan, DISM is also a built-in tool for fixing files linked to Windows essential working. Start a command prompt in administrator mode and type in:
DISM /Online /Cleanup-Image /RestoreHealth
Again let the process completely finish and then reboot your system.
Scan for viruses and other malware
Viruses and other malware can seriously damage the system and with it rstrui.exe along with it. Scan your system with Windows defender or even better with some other dedicated security suite to eliminate malicious threats if they exist.
Update Windows
Keeping Windows updated can bring you more good than harm, it is very advisable to keep it up to date all the time so all security leaks and bugs are repaired and that you have your OS in top-notch working order.

Finally upgraded to Microsoft’s newest OS, but the performance is a bit sluggish? Here are a few useful tips you may not have thought about that could significantly transform your experience!
How to speed up Windows 11?
1. Disable startup programs
There are many programs that launch right on startup that really aren’t essential. This, in turn, causes your PC to launch and run more slowly.
To check which programs are enabled on startup, go into the Task Manager and select the Startup tab. Find every program that doesn’t need to launch immediately, right-click on it and press ‘Disable’.
This will not shut down the program in that instant. It’ll just prevent it from running automatically as you turn on your PC. You can always launch it manually when you need it.
2. Expand your memory and storage
If you want your PC to run super smoothly, you need to have enough memory to support that. This is especially significant for those of you who love to multitask. Upgrading your RAM gives your PC more space to store the temporary data it needs to complete processing tasks. In other words, processing takes a lot less time.
Your long-term storage is equally important. Hopefully at this point you’re already using SSD over HDD, since this type of storage offers a faster boot time.

In any case, we recommend expanding your storage capacity. The more files and data you store, the more there is to load, significantly influencing your PC’s speed. Larger storage capacity means new data and essential updates can be stored comfortably, preventing any strain on your PC’s performance.
3. Clean up disk space
If you aren’t willing to upgrade your storage just yet, the least you can do is clean up your storage right now.
Aside from manually deleting stuff you no longer need, you can also get rid of temporary files that clutter up your storage and eat up performance for no reason. To get to them, click Windows + X and select ‘Run’ (or just type it in the search bar).
A small window will pop up, where you need to type %temp%. This will take you to a whole folder full of all the temporary files you can remove without thinking twice.
For those who upgraded from Windows 10, there’s a neat trick to get rid of potential leftover files you don’t need on your brand new iteration. Only do this if you’re 100% sticking with Windows 11, though. Go to System > Storage > Temporary files. Make sure to only leave ‘Previous Windows Installation’ and ‘Windows Update Clean-up’ checked and click on ‘Remove files’.
Lastly, make use of Windows 11’s fantastic Storage Sense feature. Turning it on will enable your PC to constantly watch out for junk or unused files to optimize your PC’s performance to the maximum.
4. Install pending updates
This one should go without saying, but pending updates can be detrimental to your Windows 11 performance. The longer you leave them untouched, the more bugs the outdated programs and patches can cause. So, make sure to regularly check for updates and install them as soon as they’re available.
5. Disable visual effects
As cool as visual effects, animations, shadows and transparency are, they can also put quite a toll on your computer’s speed. On a newer setup this generally shouldn’t be a problem, but if you do notice a drop in performance, definitely consider turning off some of these settings.
To do this you can go to the Control Panel, System Properties and click the ‘Advanced’ tab. In the Performance section, choose Settings. If you’d like a quicker way to get to the dialog (Performance Options) with Visual Effects, you can also type sysdm.cpl in the search bar.
Once there, you can either have your PC choose what’s best, choose the best appearance or the best performance. The other option is to manually toggle the effects off and on. The biggest obstacles to speed are taskbar animations, window shadows, control/element animations and animations upon minimizing/maximizing.

In the same vein, you should go to Settings > Personalization > Colors and disable Transparency, to prevent your computer from doing overtime just to hit the aesthetic appeal.
6. Get rid of bloatware
Bloatware is one of the biggest culprits of slow computer speed.
Pre-installed software that’s pretty much useless but takes up valuable system resources has been around since day one. No matter which device or platform you’re talking about. Luckily, a lot of it is removable, making it easy to lighten the load on your device.
To boost your Windows 11 computer, go to Settings > Apps > Installed apps.You’ll probably see a bunch of apps you don’t want or need. Click on the three dots next to each one you want to remove and press ‘Uninstall’.
Aside from helping optimize performance, removing bloatware has another great benefit. Unfortunately, often this pre-installed software is quite vulnerable, exposing you to great risk of cyberattacks. So, removing it definitely improves your device’s security and gives you at least some peace of mind.
Summary
These are a few of our fastest tips for boosting performance. There are other, more complex and time-consuming ways, of course. If you’ve tried these quick ones and still need advice on how to improve your PC’s speed, feel free to reach out!
If you are trying to update your Windows 10 computer but are not able to do so since your computer is running low on storage then this obviously indicates that there is not enough disk space available on your drive where Windows 10 has been installed. As you know, when Windows 10 downloads the update packages, it extracts them in a separate folder which means that there should be enough space on that particular folder for the update to begin with. Windows do not really check systems for any adequate space requirements before it even initializes the update or upgrades and you only get to know about it right when the update process starts.
On Windows 10 thin clients or the ones with embedded systems that have limited storage space, when Windows Update runs, the update initialization may fail because as pointed out, Windows does not check systems for adequate space requirements so you may have to do the work for them by making sure that your disk has enough space available. Here are some suggestions you can follow to resolve Windows 10 update issues on computers with low storage space.
Option 1 – Delete the files from the Download folder
Since you are going to delete everything manually, you need to create a backup for all your important files which you may have placed in the Download folder. After you create backup copies of important files, delete the files from this folder or you could simply tap the Shift + Del keys to remove the files permanently after you selected them all.
Option 2 – Change the Windows Update Folder location
You might have to change the Windows Update folder location where Windows download all the files need to update the operating system if you cannot really create some space on your primary driver. So all you have to do is set the drive with enough space available for the update to be completed.
Option 3 – Uninstall apps and programs you no longer use
In some cases, apps and programs take up a lot of space on your drive. So if there are programs or apps that you no longer use, you can uninstall them to save storage space. To do so, follow these steps:
In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
From there, look for the apps and programs that you no longer use and right-click on each one of them and click on Uninstall.
Option 4 – Move files to another drive
This is another thing you can try. You can move files, especially the ones with large sizes, to another drive to make up space on your drive. After that, install the updates once again.
Option 5 – Reduce on-drive files from Cloud services
If you are using tons of cloud backup services such as OneDrive and Dropbox, you might want to consider reducing the number of files you have on those cloud backup services. You can do what you’ve done on option number three and have those files moved to another drive to free up storage space.
Option 6 – Empty the contents in Recycle Bin
As you know, the files that are deleted from your computer goes to the Recycle Bin first. So if you have not emptied Recycle Bin for a long time now, the files you delete are still actually taking up space on your drive. Thus, you need to empty the contents in the Recycle Bin to save storage space.
Option 7 – Clean up temporary files
You can use the Windows 10 Storage Sense feature which can clean all the temporary files from your computer. To use Storage Sense, follow the steps below.
Open Setting > System > Storage from the WinX Menu.
From there, you will see a list of all the local and connected storage devices along with the details on the free space.
Now make sure that the Storage Sense feature is turned On then go find a link that says “Free Up Space” and click it to open.
After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space:
Windows Upgrade Log Files
System created Windows Error Reporting Files
Thumbnails
Temporary Internet Files
Previous Windows Installation Files
Delivery Optimisation Files
DirectX Shader Cache
Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.
Computer viruses are malicious applications that have the ability to self replicate and spread over the system and various devices, just like viruses in organisms. We all know that computer viruses are bad and that you should avoid them however you can. So in this spirit, we are taking a deeper dive into what kind of viruses exist and how they function.
1. File-infecting Virus
A virus that attached itself to an executable program. It is also called a parasitic virus which typically infects files with .exe or .com extensions. Some file infectors can overwrite host files and others can damage your hard drive’s formatting.
2. Macro Virus
This type of virus is commonly found in programs such as Microsoft Word or Excel. These viruses are usually stored as part of a document and can spread when the files are transmitted to other computers, often through email attachments.
3. Browser Hijacker
This virus targets and alters your browser setting. It is often called a browser redirect virus because it redirects your browser to other malicious websites that you don’t have any intention of visiting. This virus can pose other threats such as changing the default home page of your browser.
4. Web Scripting Virus
A very sneaky virus that targets popular websites. What this virus does is overwrite code on a website and insert links that can install malicious software on your device. Web scripting viruses can steal your cookies and use the information to post on your behalf on the infected website.
5. Boot Sector Virus
These viruses are once common back when computers are booted from floppy disks. Today, these viruses are found distributed in forms of physical media such as external hard drives or USB. If the computer is infected with a boot sector virus, it automatically loads into the memory enabling control of your computer.
6. Polymorphic Virus
This virus has the capability to evade anti-virus programs since it can change codes every time an infected file is performed.
7. Resident Virus
A resident virus stores itself on your computer’s memory which allows it to infect files on your computer. This virus can interfere with your operating system leading to file and program corruption.
8. Multipartite Virus
A type of virus that is very infectious and can easily spread on your computer system. It can infect multiple parts of a system including memory, files, and boot sector which makes it difficult to contain.
