Solved Answer

The Blue Screen of Death (BSOD) is a stop error screen that is displayed on a Windows computer when it encounters a fatal system error. It is usually the result of a major software or hardware issue that prevents the operating system from running properly. When this happens, the computer will display a blue screen with white text indicating where the problem lies. In some cases, it shows an error code – 0xc000021A is our topic today.

BSODs can be caused by a variety of issues, ranging from hardware problems to corrupted system files. In most cases, the message shown is just a general one and will not provide instructions on how to resolve the issue. Luckily, there are other resources available online, and we will explain how to fix 0xc000021A crashes once and for all.

0xc000021A Error Code unexpectedly appears in a Blue Screen of Death (BSOD) window after a reboot. It may show up when trying to launch applications, do some system changes, download some software, or immediately after updating the system. As mentioned, only a generic message is displayed when this happens – it reads:

Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you. (0% complete)
If you’d like to know more, you can search online later for this error: 0Xc000021A

Unfortunately, but system restart will not help. While some users encounter BSOD only occasionally, others might even be stuck in a reboot loop, which can be particularly problematic.

How to fix Error 0xc000021A on Windows 10?

The reason why this error occurs is related to the winlogon.exe and csrss.exe files. The first one is responsible for system’s login/logout, while the other belongs to the Microsoft server/client. It is assumed that 0xc000021A BSOD emerges when these files get misplaced, damaged, or corrupted. Luckily, this issue can be fixed quite easily, so we are here to help you.

Access geo-restricted video content with a VPN

Private Internet Access is a VPN that can prevent your Internet Service Provider, the government, and third-parties from tracking your online and allow you to stay completely anonymous. The software provides dedicated servers for torrenting and streaming, ensuring optimal performance and not slowing you down. You can also bypass geo-restrictions and view such services as Netflix, BBC, Disney+, and other popular streaming services without limitations, regardless of where you are.

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
