Should I buy Windows 8.1 Pro even though I have Windows 8 Pro?

post #1 of 8
Thread Starter 
I just want to do a clean install and it seems you can't do a clean install without actually buying Windows 8.1. I can get Windows 8.1 Pro for $50 though my university. I did a clean install from Windows 7 Ultimate to Windows 8 Pro in March, so its been awhile since I did a reformat.

No. Windows 8.1 Pro is a free upgrade so why would you buy 8.1? Why not do a clean install from your Windows 8 upgrade discs?

By clean install do you mean do a clean install of Windows 8 and before changing anything or installing anything I should upgrade to Windows 8.1?

Just do a clean install with Windows 8, activate and go to the store to upgrade to 8.1 for free (microsoft account login required). Then run Disk Cleanup and that will allow you to remove the windows.old folder (windows 8) and its just like you did a fresh install with 8.1

If you only have an upgrade key for windows 8 use these steps to activate it...

1. Run the registry editor (regedit)
2. Find the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\OOBE
3. Change the value for 'MediaBootInstall' from 1 to 0
4. Open an elevated command prompt (run as admin)
5. Run the following command: slmgr -rearm
6. Reboot
7. Re-try activation if not already activated.

When you open Disk Cleanup, click on "Clean up system files" and then make sure "Previous Windows Installation(s)" is checked then click OK.

Thanks.

However, I asked this same question on another forum and it seems you can to a clean install of Windows 8.1 without having to buy it as long as you currently have Windows 8.
