Most of the time, your Windows product key is on a piece of paper stuck in a hard-to-reach spot on your machine. But you can use it to find your Windows 11 product key if you know a few words and how to use the operating system. Finding a purchase key for Windows 7 is almost the same as it was for Windows 10, but there are a few small differences.
This how-to guide will show you how to find your Windows 11 product key without a sticker on your computer by using the operating system.
3 Simple Ways to Find Your Windows 11 Product Key
Be aware that these methods work best on computers that have had Windows 11 since they were bought or on Windows 10 computers that have been updated to Windows 11 through a patch. Product keys for business PCs are given out in a different way and can’t be found this way.
1. Use The Command Prompt In Windows 11
The easiest way to find your Windows 11 product key is from the command line. In Windows 11, open the search box and type “command.” Find the command prompt (Figure A) in the search results and click the Run As Administrator link to go to the command prompt screen.
The command will show your Windows 11 product key right there on the screen of the command line.

Use the left window of the editor to find this key:
Figure C shows that the BackupProductKeyDefault key will show a real Windows 11 product key. (Note that the task window or PowerShell might tell you something different about this key.)
