Regardless of which type of Windows installation you choose, it’s always a great idea to back up your data before beginning the process. Given that Windows 7 is no longer being supported, this key is the only way to get a legitimate copy of Windows 7 from Microsoft.

Make sure to have this on hand – If your PC’s restore or Windows 7 disk came in a paper or plastic sleeve, the key would likely be on that. Avoiding constant pop-ups from Windows asking you to validate the install with the key is also a nice bonus. This key allows Microsoft to check whether you have a legitimate, legal copy of Windows 7, although updates are no longer available. Once you’re done installing Windows 7, the OS will ask you to put in its CD/Serial key.

We highly recommend that you upgrade to Windows 10 immediately. If you decide to disregard this advice, please note that we cannot be held responsible for any errors or issues that may occur. As such, Digital Trends does not recommend that our readers use Windows 7 on their devices. Unfortunately, Microsoft no longer offers official support for Windows 7 since January 14th, 2020, which leaves users with few options if their PCs go belly-up.
