Solved Answer


It’s not a secret for anyone using Windows that Windows 8 and 10 OS are very prone to system errors. Microsoft is continuously working on improving the system and fixing errors on Windows running PCs/laptops/tables. Unfortunately, but as soon as one error is fixed and the update released, new errors change them, and the story goes on again.
Although Windows 8 users have to deal with errors frequently, it doesn’t beat Windows 10. This OS is particularly prone to errors like 0xc000021a more often. Although Windows 10 has been released a year ago, two big updates have already been released, but, unfortunately, the problem with errors doesn’t seem to be decreasing. Well, we are here not to judge or evaluate Windows. In this short post, we would like to help you to fix one of the Windows 8/10 errors, which is 0Xc000021A.

0Xc000021A Error Code appears in a Blue Screen of Death (BSOD) unexpectedly. It may show up when trying to launch software, do some system changes, download some software, or immediately after updating the system. 0Xc000021A Error says:

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. As soon as Windows reloads, you will see 0Xc000021A error again. In most of the cases, this error shows up when the system is booted. The reason why this error occurs is related to winlogon.exe and csrss.exe files. The first one is responsible for system’s login/logout, while the other belongs to 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.

Prevent websites, ISP, and other parties from tracking you

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.

A VPN is also crucial when it comes to user privacy. Online trackers such as cookies can not only be used by social media platforms and other websites but also your Internet Service Provider and the government. Even if you apply the most secure settings via your web browser, you can still be tracked via apps that you are connected to the internet. Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speed.

Therefore, to stay completely anonymous and prevent the ISP and the government from spying on you, you should employ Private Internet Access VPN. It will allow you to connect to the internet while being completely anonymous, prevent trackers, ads, as well as malicious content. Most importantly, you will prevent the illegal surveillance activities that NSA and other governmental institutions are performing behind your back.


Recover your lost files quickly

Unforeseen circumstances can happen at any time while using the computer: it can turn off due to a power cut, a Blue Screen of Death (BSoD) can occur, or random Windows updates can decide to reboot the machine when you went away for a few minutes. As a result, your schoolwork, important documents, and other data might be lost.

Additionally, you might also be attacked by malware that can corrupt your Windows or encrypt files with a robust encryption algorithm, and ask for a ransom in Bitcoin for the decryption tool. Cybercriminals might not deliver what they promised, however, so it is better to attempt alternative file recovery methods that could help you to retrieve at least some portion of the lost data.

Data recovery software is one of the options that could help you recover your files. Once you delete a file, it does not vanish into thin air – it remains on your system as long as no new data is written on top of it. Data Recovery Pro is recovery software that searchers for working copies of deleted files within your hard drive. By using the tool, you can prevent loss of valuable documents, school work, personal pictures, and other crucial files.
