It may be that [...] counterfeit software.

Hello, or good evening to everyone! So a while ago I posted this message:

START OF POST "So here's the thing, I’ve had a problem for some time and this problem is starting to annoy me because I can’t seem to get rid of it.

One day I tried to install the Windows 7 update to Windows 10, but I didn’t really like Windows 10 for one reason or another and so I switched back to Windows 7... and since I returned to Windows 7 I no longer have a wallpaper (even if I add one it disappears 10 minutes after adding it) with the permanent message at the bottom right "Computer number XXX. This copy of Windows is not genuine" there’s my wallpaper.

Then there is this message that appears and reappears very often and tells me:

"/!\ You may be dealing with counterfeit software.

To access all Windows features, such as all Windows Update updates, get the latest updates and technical support, your Microsoft Windows copy must be validated

Log me in and validate now"

Here's that famous message that appears every time I turn on my computer since I returned to Windows 7...

I’ve consulted many sites and forums but the questions dated from 2010... So if you could help that would be really great!! Thanks a lot!" END OF POST

This problem was subsequently solved. Only today my computer returned to "counterfeit" mode during a simple reboot...

The icing on the cake is that I can’t find the comment from the one who managed to get my computer unblocked...!

Thank you very much!
