After installing Windows 10 in a PC the shit went crazy so I decided to do a restore, but guess what Windows 10 messup the recovery drive so I had to restore back to 8.1, but the damn key was not on the laptop lol, So I use this cool tool to retrieve it 🙂 It’s call RWEverything click it to download it, or you can get it from here https://www.imfiles.com/allfiles/RwV1.6.8.1.zip
So basically open the program and it looks like this
Now click on the ACPI table than on the toolbar click on MSDM Than you will see the key where it says Data 🙂
