Windows 10: Can I activate Windows 10 with Windows 7 OEM?

I want to completely format my old PC and reinstall Windows. According to ShowKey Plus it has Windows 7 OEM key in firmware, does this mean that when I reinstall Windows 10 it will automatically activate using this key, if not is there any way to activate this without buying a new key. Thanks in advance.

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

 

Windows 10 Activation (Insider)

I bought Windows 7 Pro OEM key from G2Play.net for 12€ to upgrade to Windows 10 Pro - worked like a charm but be advised if you buy a OEM key you can not download the Win 7 iso from microsoft and have to get it elsewhere.

 

windows 7 8 or 10

We can kick Windows 8.1 to the curb right away. Windows 10, in tablet mode, is effectively identical...not that I would recommend using tablet mode.

The only advantage Windows 8.1 has over Windows 10 is Windows Media Center. Windows 10 doesn't have it and likely will never support it. Microsoft wants you to buy an Xbox One and use that, instead of your computer, for media, and then stream it to your Windows 10 machine from the Xbox One. Windows Media Center on 7 seems to not be getting updates anymore (worked off of Vista guide info which shut down). Windows Media Center on 8.1 costs $10 to upgrade on Pro or $100 to upgrade on Home.

The Windows 7 upgrade (should still work for about 10 months yet) requires:
1) Install Windows 7.
2) Activate Windows 7.
3) Upgrade to Windows 10.
4) Activate Windows 10.
At this point, you could either stay with Windows 10 or downgrade to Windows 7 by doing a clean install.

Personally, I would go with Windows 10. It has some bugs but it is pretty good overall.
