Record the product key. You should see the 25-character product key to the right of the hard drive’s name; this is the product key of the suspended computer.
- You can take a screenshot or write down the key to make sure you have access later.
Advice
- The Windows product key may be on the installation CD, the code printed on the computer packaging, the sticker in the battery tray, or under the computer base.
- Some computers will display a virus warning when downloading and running ProduKey. This is because ProduKey has the ability to access your product key, not because the program is malicious. As long as you download ProduKey from the official website, you don’t need to worry about the virus warning.
Warning
- Using someone else’s product key to activate your Windows software is a violation of Microsoft’s terms of use.
- When removing the hard drive from a suspended computer, you must be very careful. If possible, it’s best to ask a professional to do it for you.
