To downgrade Windows, you’ll need a Windows 7 Professional installation disc and a valid license key for it. Neither Microsoft nor your computer manufacturer will provide this disc or key for you – you’re on your own when finding it, although Microsoft insists you should find a legitimate copy instead of downloading one from an illicit website. Because of the free Windows 10 upgrade coming for Starter, Home Basic, Home Premium, Professional and Ultimate Windows 7 and Windows 8.1 editions, I did a downgrade from Windows 8.1 Enterprise to Professional, keeping all my files, applications and settings. If an important program or hardware device you use doesn’t work on Windows 10, you’ll want to downgrade. If Windows 10 just seems unstable, you’ll want to go back to your previous version of Windows and wait a while longer before attempting an upgrade. Or, if you’d just rather hang onto Windows 7 for a while longer, you can downgrade.
If this is not an option available to you, you will have to purchase the Windows 7 Professional license.

When I checked a few minutes ago, Amazon was offering OEM Windows 7 Professional packages from multiple sellersat prices ranging from $101 to $150. When I checked just now, a package specifically intended for refurbished PCs cost only $50 for a 64-bit copy.

There are no technical limitations to prevent you from using OEM software on your own PC, although this software will work only for a clean installation and not for an upgrade. In the past, Microsoft has been remarkably inconsistent in its advice to customers about whether this practice is allowed. (See 'Is it OK to use OEM Windows on your own PC? Don't ask Microsoft.')
Always smart to do while things are printing right? That did not do anything. I remembered there is a 'theme' setting in the general PM options. Fiddled with Windows display settings.
