The main element you need will be in one of 3 places:
Kept in software on your PC: When you (or your PC manufacturer) installs Windows, Windows stores its product key in the registry. You may draw out this product key, and-often-enter it when reinstalling Home windows on your PC. Crucially, you’ll need to get it from your operating-system before you start reinstalling Windows or it could be deleted if you format your hard drive.
Printed on the sticker: Buy Windows Key Online Several PCs use a technology called “System Locked Pre-installation, ” or SLP. If perhaps your PC uses this, the product key on your PC-the one trapped in the registry, and normally the one key-viewer applications display-will vary from the actual key your PC needs.

It’ll all happen automatically.
Be sure to use the same version and edition of Glass windows the computer was included with. In other words, if it came with Windows-7 home premium, you can’t mount Windows 7 Professional.
