Issue: How to fix Windows activation error 0xc0020036?

Hello. I was trying to upgrade to Windows 10 from Windows 8.1 today. Once complete, I have received a strange error  0xc0020036, which claims that I am not running Windows non-core edition. I bought Windows from the official store back when Windows 8.1 was released, so my license is genuine. Any help with this is appreciated.

Solved Answer

Some users said that they receive an 0xc0020036 error when trying to upgrade a Windows machine – the issue is most commonly present after installing Windows 10, which results in failure to activate the copy of the OS correctly. While activation errors are commonly present for those who use an illegal copy of Windows, this issue turned out not to be the case, as most users who complained about this, in fact, have a genuine license key.

In some cases, users reported that the 0xc0020036 error only occurred after they have applied the most recent Windows updates and that it occurred in conjunction with the 0xC004F012, 0xC004F074 or 0xC004C003 error. These instances were plenty after the release of the 1803 update,[1] where thousands rushed to Microsoft forums to report this issue.

Here is the message that users received:

Windows Script Host

Error: 0xc0020036 On a computer running Microsoft Windows non-core edition, run 'slui.exe 0x2a 0xc0020036' to display the error text.

There could be several reasons why this error code is shown to users – it may differ from machine to machine. As already mentioned, sometimes the problem lies within Windows updates, while others might receive it due to corrupted system files or the key itself.

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.
