Two characters are missing on a torn Windows 7 Professional ACER sticker.

While I can build a list of matching product keys with combination generator like this one, how could I check its validity?

I found http://janek2012.eu/ultimate-pid-checker/ but I'm not sure it can perform a check against OEM keys.

UPDATE

// PID Checking ends here

Summary:

       Valid:       0 keys
       Invalid:     576 keys
       Malformed:   0 keys
       Other:       0 keys
 incl. Blacklisted: 0 keys

 Total time:  3 975,826 seconds

UPDATE 2

Sorry, there was a mistake in my list! One char was wrong.

It finally worked:

  • Do you have an installation with the key? If you do this is easy to solve, if you don't, contact Acer for assistance.

  • "but I'm not sure it can perform a check " - So you didn't even try?

  • Also taking a good picture of the sticker, then use image software to adjust the image to read the product key the eye cannot see.

Enter your product key on this page: https://www.microsoft.com/en-us/software-download/windows7

If it tells you it's an OEM key, you're good!

FYI... never enter your key on a random website. That is a terrible idea.

  • You are right. While I couldn't use Microsoft page as I had many keys to check, I disconnected network during key checking (PID checker could send key to a remote server).
