Upgrading Windows 10 version from Home to Pro with Win7 OEM License, Do I need to backup?

[Aleshark06]

Hello everyone,

i have a HP Pavilion Gaming Desktop 690-0039nl and I want to upgrade my Windows 10 HOME license with a windows 10 PRO license.

I don't have a Windows 10 PRO license but only a valid Windows 7 PROFESSIONAL OEM key that certainly works if I have already installed the Windows 10 pro version.

In case it doesn't work, how can I go back to Windows 10 HOME? If I am obliged to reinstall windows, how can I reinstall all HP apps that were included in my HP Pavilion Gaming Desktop 690-0039nl ?? 

Thanks for your kind reply,

Have a good day.

Hello
if you can, your best bet would be to try it with another hard drive.
Otherwise, you will need to create the recovery kit, you can also check if hp cloud recovery is compatible with your model
Some computers do not allow you to download windows recovery

Hi, @Aleshark06 

See this article...Maybe this procedure still works.

If it doesn't, then no changes will be made to your W10 Home installation.

Indeed @Paul_Tikkanen 
we must be able to switch to another version without too much problem
but better to prevent than to cure, and to have something to reinstall in the event of a problem
I suggested using another safer HDD
but we can also try to use a pre-upgrade clone system as well
in any case, if you need one day, you have to create the recovery kit if the computer allows it

Hi, @Prométhée 

I was referring to the first method mentioned in the article...simply enter the W7 product key by following the instructions.

If the key is not accepted, the upgrade will fail and no changes will be made to the PC.

I 100% agree with you that if a clean install has to be performed, then it should be done on another drive if possible, and a recovery drive be created in any case with the HP cloud recovery tool.

Absolutely @Paul_Tikkanen 
but I do respond if ever the key works which is possible but it goes wrong, for some reason it does not work well during the upgrade
It should be possible to go back, but not always easy, in which case it is better to have the recovery kit
After I have never tested, if we give the key that it is correct, when must we validate, or if then, it is direct
not the courage to read everything and researched
But we could be less fixed, the key works or not indeed
good Sunday
