I just reinstalled my Windows 7 Ultimate Edition that I upgrade to Windows 10, but it wont let me.

[Windows Central Question]

I need to know how to reupgrade to Windows 10. I had to reinstall windows and only had my Windows 7 Ultimate Disk and now it wont let me upgrade it to Windows 10 again.

Download the corresponding Windows 10 image from Microsoft (which, I believe, would be Windows 10 Pro). You can use your product key from Windows 7 to install Windows 10, since you have upgraded once already.

You do need to use the same Microsoft Account as you originally registered your digital rights to 10 under.
