If you delete Windows.old folder after upgrade and choose to keep nothing from the previous installation, is it considered as a clean install?
You could very well consider it a clean install, but is there a particular definition of the term that you need to fulfill for some reason?
dang, so I added an extra 8GB of memory to my computer and win 10 became invalidated. I thought only motherboard changes or main windows partition/HDD would revoke the key.![]()
Just call Microsoft and they'll validate the Win10 install.
So I am back on windows 8.1 with classic shell installed, its not so bad. Just wonder if windows 8.1 will get some of the directx 12 updates?
No.
Does anyone know if I have Win8 and I install win 10, and then after the period for free win 10 expires, I format the computer, will I still have the option to upgrade on clean win 8 install?
Once you upgrade to 10 (free within the one year period), you'll have a Windows 10 product key (associated with your hardware). You can then re-install Windows 10 at your leisure.
I'm not sure whether the 10 upgrade notification/download will automatically come up in the future, but you could still upgrade via manual download of the installer/ISO.
