Hello everyone, I just signed up, I read your post a few times, and I congratulate you for the work they do.
I tell you I certainly had my pc Windows7, a PC purchased in a large hypermarket. I upgraded to Windows 10, but had problems with some older programs, which could not be opened, but used them, so I decided to return to Windows 7, but I've been surprised that tells me once again to 7, my copy of Windows 7 is not oriiginal! what can I do? if you buy well,, already installed. any solution? I tried to restore, but only gave me the restore point when I uninstalled 10. thank you very much and greetings

Hello welcome.

Copy of a previous post of mine the solution should run you:
It is a known effect that occurs after an upgrade (has happened with flash, for example) or after installing a program does not fully support.

The solution provided by Microsoft is this:

Start / Programs / Accessories / right mouse over sistems symbol >> Run as administrator.
There you give this command and hit Enter

slmgr / COLR

will parade a long litany of files on the screen. It is running the reinstatement of the license files.

Once finished go to Control Panel / System and see if Windows / appears on. If not, turn it on (Activate now).

Check now if your Windows is as legitimate

Only if that did not work need to reset the license: you return to run command prompt as administrator, give this command and hit Enter

slmgr / rearm

A window is displayed indicating that it has implemented and saying to restart.
Do that and when you have booted go to Control Panel / System and active again Windows 7.
With this your problem should be resolved.

Cheers

PS: All commands have indicated are valid only for Windows 7. They should run on a Vista even if the same problem
