How to disable Windows Defender in Windows 11?
It is well known that antivirus programs are essential to protect computers, but users often have all sorts of problems choosing and installing them. In view of this, the developers of the Windows 11 operating system provide a built-in Defender antivirus, which mistakenly blocks the installer winrar crack.

As practice has shown, Microsoft Defender is not at all ideal – it consumes a lot of computer resources and is capable of causing other problems to the user.
