Helpful hint for people asking for Windows keys:
ShowKeyPlus - available on the MS store - can retrieve the product key from your current Windows installation, and you can use this key to reinstall Windows with clean installation media.
Also, you can back up your existing drivers and restore them after the clean installation. Here’s how:
Open Command Prompt as Administrator and run the following command:
dism /online /export-driver /destination:C:\DriverBackup
Replace C:\DriverBackup with a path to a folder where you want to store the drivers.
After Reinstalling Windows, for any missing drivers:
Right-click the device and select Update driver.
Choose Browse my computer for drivers.
Point to the backup folder on the USB drive.
