6 solutions to fix Widnows activation error 0xc004f200

One of the most strange errors users of Microsoft Windows receive is the xc004f200 Windows not genuine error.
I say strange because it pops up even when one is using a valid Windows activation key. More interesting is the fact that Windows could have been showing it’s activated all along and working seamlessly only to abruptly claim it lacks a genuine activation.
What follows are endless issues including the operating system disabling some features. And again, the xc004f200 complications are not limited to Windows and will sometimes surface when transferring Microsoft Office to new PCs.
Well, don’t fret if you have been confronted by this problem for it has plenty of easy-to-implement solutions.
But before we discuss them, let’s see what triggers the 0xC004F200 (not genuine) warning.
What causes error 0xc004f200?
Most users have been encountering this issue after an update. For others, it’s when installing Office software on new PCs or after a hardware upgrade.
Now, the issue is not due to a software misconfiguration but rather because of the nature of Microsoft’s licensing arrangements.
For instance, your MSDN key or TechNet Product Keys may become blocked if used in other machines since they are meant to be used by a single person.
But you may be able lucky and manage to use it for a while before the system senses. Your luck runs out with a system change, for example, after reinstalling Windows.
Again, despite users being aware of the strict Microsoft licensing terms, some users still give away product keys illegally or resell them on auction sites. Microsoft usually detects once such a key has been installed in a second machine and blacklist it preventing further use.
So in short, the error emanates from Microsoft thinking that your software is pirated and happens to even users who have installed genuine programs.

Here are our recommended ways to get rid of this challenge.

How to Reset the PC To A Normal Boot
Remember to return your PC to be starting normally after you’re done troubleshooting in clean boot.
