Issue: How to fix Windows activation error 0xC004D302?

Hello. Today I received an activation error 0xC004D302 on my Windows computer. Some functions stopped working. What should I do?

Solved Answer

Windows requires an activation key to work properly. If for some reason the license files become corrupted, users can encounter activation errors. We previously wrote about 0x8007232B, 0x87e107f9, 0XC004F009, and many other activation errors.

When Windows is not activated, users cannot change the wallpaper, customize the lock screen, change icons, etc. The most worrying thing is that such a device is not eligible to receive the latest security patches and feature updates which can make the system vulnerable.[1]

Usually, they can be fixed by using the Windows activation troubleshooter, installing Windows updates, or using the phone activation option. Recently, some people encountered a 0xC004D302 Windows activation error. This error appears on computers running Microsoft Windows non-core edition. The full message reads as follows:

Software licensing service version: 10.0.16299.15

Error: 0xC004D302 On a computer running Microsoft Windows non-core edition, run 'slui.exe 0x2a 0xC004D302' to display the error text.

Most of the time, the error is triggered by issues in the Machinekeys folder, reactivation of trusted data memory, or attempts at executing different commands after executing slmgr. Vbs /rearm without restarting the computer. In this guide, you will find 4 steps that should help you fix Windows activation error 0xC004D302.

Access geo-restricted video content with a VPN

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.
