Can I still Install and Activate Windows 7 April 8, 2020, Its now several months past the “End of Support” for Windows 7 but you can still install and activate Windows 7.
Be sure to install the latest Device Driver updates for your PC’s make and model number after installing Windows 7 or you may not be able to connect to the Internet.
I used a Windows 7 Professional with SP1 installation DVD to install Windows.
If at all possible create and image backup to an external USB drive, this will give you a second chance if something should go wrong when installing the updates, just restore the backup using the “Recovery Media” which you should create after installing the backup software.
You should have a 30 day grace period before you need to use your product key to activate Windows. So hold off until you have finished installing the Windows Updates.
I ran Windows Update and found that there are about 200 updates to install. I suggest installing in small group putting preference on the “Service Stack” updates.
