How to Repair BSOD Stop Error code 0xc000021a in Windows 10

If you suddenly encounter the SPECIAL POOL DETECTED MEMORY CORRUPTION Blue Screen error with a bug check value of “0x000000C1” while you are using your computer then it might be due to some problem with the hardware of your Windows 10 computer. According to security experts, it is most likely caused by the physical RAM which could be due to some error in the Realtek driver for Wireless USB 2.0 as well as corruption of the files inside the RAM, and so on. This kind of problem indicates that the driver wrote to an invalid section of the special pool. On the other hand, system files like the rtwlanu.sys or nvlddmkm.sys can also trigger the SPECIAL_POOL_DETECTED_MEMORY_CORRUPTION Blue Screen error. To resolve this Blue Screen error, you can use the options provided below as reference but before you do that, make sure to create a System Restore point first. After you have that covered, proceed to the given options below.

Option 1 – Delete the settings of the Driver Verifier Manager

• Open the Driver Verifier Manager using the Start search.
• After that, select or click on the “Delete existing settings” option and then click on Finish.
• Reboot your computer and see if it fixes the Blue Screen error or not.

Option 2 – Try to update or rollback your Network driver

If you have updated the driver software as of late and you suddenly got this BSOD error, you might have to roll back the device driver – in other words, switch back to the previous working version. To do that, follow these steps:

• Tap the Win + R keys to launch the Run window and then type in the “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.
• From the list of Network Drivers, look for “Realtek <Model> Wireless LAN 802.11n PCI-E NIC” and then right-click on it and select Update Driver.
• Restart your PC and see if it helped in fixing the BSOD error.

Note: If you see any of the following entries under the Network drivers, you might want to download their latest available versions from each one of their manufacturer’s websites.

• Realtek High-Definition (HD) Audio Driver
• Realtek Card Reader Driver
• Realtek Local Area Network (LAN) Driver

On the other hand, if updating the Network driver didn’t help, you can also try to roll back to its previous version.

• Open the Device Manager again and then look for Network Drivers.
• Next, select Realtek <Model> Wireless LAN 802.11n PCI-E NIC from the list of Network Drivers and then double click to open a new mini window.
• After that, make sure that you’re on the Driver tab and if you are not, just navigate to it then click the Roll Back Driver button to switch back to the previous version of the Realtek driver.
• Now restart your computer to successfully apply the changes made.

• First, open This PC and right-click on your operating system partition for Windows.
• Next, click on Properties and navigate to the Tools tab.
• Then click on Check under the Error Checking section.
• After that, a new mini window will be opened and from there click on Scan drive and let it scan your disk drive partition for any errors and then restart your computer.

Option 4 – Use the Windows Memory Diagnostics

Since the problem has something to do with the physical RAM, you need to use Windows Memory Diagnostics. To run it, refer to these steps:

• 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)

USB Kill, a USB device is able to fry and damage your computer, mobile phone, router, etc. This device is quite dangerous and can kill electronics the moment it is inserted into an available port. By now people should know that they should not put unknown USB sticks into their devices because of potential virus and malware threats but this raises using unknown sticks to a whole new level.

Kill kits are not really new to the market, they have existed before but lately, technology really progressed and the latest USB sticks are really good, their success rate is around 95% which is pretty high and should not be taken lightly.

The second thing that you really should not play with strange USB sticks is that they dropped in price really hard, although top Kill kits will still go as high as around 300 USD, there are really cheap ones lurking in Ali Express that are just 6 USD!!! that makes them affordable devices for the mass market.

The device is made to take energy and current from the port it is plugged in, multiply it and release its charge back into the device, successfully frying some components immediately. Some more professional Kill sticks can even fry devices even when the device itself is not powered and can be even started remotely.

The point of this article is to make you aware that you should not in any kind of circumstances use and plug-in USB sticks into your devices that you do not know where they come from, especially from the mail!!

If you suddenly get a message telling you that “Your Windows license will expire soon, You need to activate Windows in Settings” on your Windows 10 computer but you know that your Windows 10 is already activated. Worry not for this post will help you get rid of that error message right away. Before you get started, make sure that you have the Windows product key with you. If you don’t, you can get it by running the following command in an elevated Command Prompt:

wmic path SoftwareLicensingService get OA3xOriginalProductKey

Take note of the product key and then proceed to the options given below.

Option 1 – Try activating Windows 10 again or use another product key

• If you’re sure that you have the correct product key, click the Go to the Settings button.
• After that, click the Activate button once again.
• If you have another license key, you can also use that as well, just simply click on the Change product key.
• Then enter the new product key and click on Activate. That should fix the problem, if it doesn’t, refer to the next option below.

Option 2 – Try to reset the licensing status

• Click the Start button and then type “cmd” in the Search box and then tap Ctrl + Shift + Enter to open an elevated Command Prompt.
• Next, type the “slmgr –rearm” and hit Enter to reset the licensing status.
• Restart your computer and check if the error is now gone or not.

Option 3 – Try uninstalling the product key and re-enter it once more.

• The first thing you have to do to uninstall the product key is to know the Activation ID of your Windows installation. To do so, open an elevated Command Prompt and type this command, and hit Enter – vbs /dlv
• After you enter the command, you should see the licensing status and Activation ID. And to get all the Activation IDs of all the installed Windows versions, key in this command and hit Enter – vbs /dlv all

Note: The “/dlv” parameter will give you the license information for the installed operating system.

• After you enter the second command, you should see a Windows Script Host window with all the Windows licensing and activation status. Take note of the Activation ID.
• Next, in the same elevated Command Prompt, type this command – slmgr /upk <Activation ID>

Note: In the third given command, “/upk” stands for “uninstall product key”. This parameter uninstalls the product key of the current Windows edition.

• Restart your PC. After that, your computer will be in an unlicensed state so you need to re-enter the product key again.

Option 4 – Try rebuilding the Tokens.dat file.

The issue might be caused by a corrupted Tokens.dat file. The Tokens.dat file is a digitally signed file that stores most of the Windows Activation files so if it is corrupted then no wonder you’re having activation issues. To rebuild the Tokens.dat file, refer to these steps:

• From the WinX Menu, open an elevated Command Prompt.
• After opening Command Prompt, you need to type each one of the following commands and after you type each command, hit Enter.
