How to Find Your Microsoft Office 2010 Product Key

How to Find Your Microsoft Office 2010 Key Code?

You can avoid the process below by checking for the product key on the disc sleeve, manual, or email receipt that came with your purchase of Office 2010.

In addition, assuming that Microsoft Office is still or has been recently installed, a valid product key that requires reinstallation of Office will be stored in the Windows registry. Unfortunately, digging it from there will not be much help because it is encrypted.

Fortunately, some free programs called important search tools can not only find and decrypt this super-important 2010 product key.

Follow these steps to find and display a valid Microsoft Office 2010 product key using the free License Crawler program:

The following procedure also applies to finding product keys for any Microsoft Office 2010 or 2007 suite, such as Office Professional 2010, Office Professional Plus 2010, and Office Ultimate 2007. You can use these steps even if you have only one member. Kit installation. For example, the 2010 or 2007 version of Word, Excel, Outlook, etc.

  1. Download LicenseCrawler. This is a free, and portable  program, as well as one that I’ve tested for valid product key extraction for Office 2010.
    • Note: You’re welcome to try a different free key finder program but I like LicenseCrawler for Office 2010/ product keys the best, plus I love that it’s portable and leaves nothing behind on your computer. It’s not like you’re going to use this program twice… hopefully not, anyway.
  2. After downloading, extract the ZIP file you now have to some folder and run LicenseCrawler.exe.
  3. Once LicenseCrawler opens, click or tap Search.
    • Tip: There might be an advertisement or some other screen that you have to wait for until it closes, or that you have to click to close. Just follow any on-screen instructions to open LicenseCrawler.
  4. Wait for LicenseCrawler to scan your entire registry, looking for registry keys that contain product key information. Since you probably have many more programs than Microsoft Office 2010 installed, you’ll probably see lots of entries.
  5. Once LicenseCrawler is done scanning the registry, scroll down through the list and look for the entry that starts like one of these:
    • HKEY_LOCAL_MACHINE\Software\Microsoft\Office\14.0\…
    • HKEY_LOCAL_MACHINE\Software\Microsoft\Office\12.0\…
    • The 14.0 entry corresponds to Office 2010, while 12.0 corresponds to Office 2007. You’ll only see one unless you happen to have both versions of Microsoft Office installed, but that’s not common.
  6. Under that entry, note the two rows, one labeled Product ID, another labeled Serial Number.
  7. The Office 2010 product key is the alphanumeric series listed after Serial Number. The Office product key will be formatted like xxxxx-xxxxx-xxxxx-xxxxx-xxxxx. It’ll be 25 characters long – five sets of five letters and numbers.
    • Note: The term serial number probably isn’t the best way to describe what this number is, but you’ll often see the terms serial number and product key used interchangeably.
  8. Write this product key code down exactly as LicenseCrawler shows it – you can either do this manually or copy it right out of the program. If you’re off by even one character, it won’t work.
  9. You can now reinstall Microsoft Office 2010, using the product key that LicenseCrawler showed you.
    • Important: Unless your edition of Microsoft Office allows for simultaneous installations on more than one computer, please know that most of the time this is not allowed. Just one computer at a time.
