As you probably know (because you've found yourself here), you must have a valid product key to reinstall Microsoft Office 2010 or Office 2007.

If you haven't already looked, 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 or 2007.

Beyond that, assuming Microsoft Office is still or was recently installed, the valid product key you need to reinstall Office is stored in the Windows Registry. Unfortunately, digging it up from there won't be much help because it's encrypted.

Office 2010 serial number I just bought a new desktop with windows 10 64 bit. I have a disk with office 2010 but the serial number is not compatible with the new systrms of nimbers how can I get Microsoft to accept my disk number so I can download it to my new computer. I will provide you Microsoft Office 2010 Product Key. You can find it below: I give you trial product but once you are satisfied and you have enough money, I highly recommend you to buy Microsoft Office 2010 Product Key to support the developers.

Fortunately, several free software programs called key finder tools are more than capable of finding, and decrypting, that super important Office 2007 or 2010 product key.

Follow the steps below to use the free LicenseCrawler program to find and then show you your valid Microsoft Office 2007 or Office 2010 product key:

How to Find Your Microsoft Office 2010 or 2007 Key Code

The following procedure works equally well to find the product key for any Microsoft Office 2010 or 2007 suite, like Office Professional 2010, Office Professional Plus 2010, Office Ultimate 2007, etc. These steps will also work even if you just have one member of the suite installed. For example, 2010 or 2007 versions of Word, Excel, Outlook, etc.

  1. Download LicenseCrawler. This is a free, and portable (no installation required) program, as well as one that I've tested for valid product key extraction for both Office 2010 and Office 2007.

    You're welcome to try a different free key finder program but we like LicenseCrawler for Office 2010/2007 product keys the best, plus we 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 to a folder the contents of the ZIP file, and run LicenseCrawler.exe.

  3. Read through the screen prompt you see now, and press the button that it tells you to press.

    There might also be an advertisement or some other initial setup screen (like a language selection or license agreement) that you have to wait for, close, or click through to continue. Just follow any on-screen instructions to open LicenseCrawler.

  4. You might see another window open that's unrelated to LicenseCrawler, but it should close down on its own and not interfere with the product key scanning procedure.

  5. 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 or 2007 installed, you'll probably see lots of entries.

  6. Once LicenseCrawler is done scanning the registry, scroll down through the list and look for the entry that starts like one of these:

    Here's what you need to know about these entries:

    • 14.0 refers to Office 2010
    • 12.0 refers to Office 2007

    You'll only see one unless you happen to have both versions of Microsoft Office installed, but that's not common.

  7. Under that entry, note the two rows, one labeled Product ID, another labeled Serial Number.

    The Office 2010 or 2007 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.

    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.

    Another way to save the product key is to go to File > Save to make a text file that contains all of the results. You'll have to sift through them again to find the MS Office product key, but at least you'll know it's forever saved.

  9. You can now reinstall Microsoft Office 2010 or 2007, using the product key that LicenseCrawler showed you.

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.

Tips & More Information

If the above 'trick' didn't work, and you're sure you don't have your email receipt or other documentation available from when you bought Office 2007 or 2010, you're left with having to purchase a new copy of Microsoft Office.

While you may have come across various free Office product key lists or may have seen suggestions to use keygen programs to create a product key that will work, neither option is legal.

What About Office 2019, 2016, or 2013?

Unfortunately, the above process does not work with Microsoft Office 2019 down through 2013. Microsoft made changes to the product key process beginning in version 2013 that made it possible to restrict the storing of the key on the local computer to nothing but the last five characters, making product key finder programs unhelpful.

When you install Office 2010, you'll be prompted to enter a 25-character product key that looks something like this:


How to find your product key

The way you can find your product key depends on how you got Office. Select how you got Office from the options below.

I downloaded Office from an online store

If you purchased and downloaded Office from an online store, the product key should be in your email receipt.

Try the following to find this confirmation email:

  • Check your spam, bulk, or junk mail folders for the email.

  • Try searching your email for the word “Microsoft” or the name of the company where you bought Office.

  • If you have multiple email accounts, check the email account that you provided when you purchased Office 2010 online.

If you can’t find the email receipt, you may be able to retrieve the information contained in the email by using the Order History link for the store you made the purchase from:

  • Here's how to view your product key if you purchased Office from Digital River:

    1. Go the Digital River download information page.

    2. Select Find my product key and enter the information requested to download software or get your product key.

  • Here's how to view your product key in the Microsoft Store:

    1. Go to www.microsoftstore.com. In the upper right-hand corner, select Sign in and enter the user ID and password you used to buy Office.

    2. After you sign in, select your name in the upper right-hand corner, and then select Order History.

    3. Locate the Office one-time purchase or individual Office app, and then select Install Office to view your product key (this doesn't actually install Office). Note that this product key won't match the product key shown in My Office Account. This is normal.

Office came in a box (with or without a DVD)

If Office came in a box, card, or disc, look for the product key on the card or on the packaging that came with Office.

If the product key isn't there, read the instructions on the package. You might be directed to go to Office.com/getkey to get your product key.

Office came on a product key card with a PIN

You can no longer redeem the 27-character alpha-numeric PIN shown on the product key card to retrieve your product key. However, if you already have your 25-character product key, and you'd like to download Office 2010, you can enter the product key at https://www.microsoft.com/software-download/office.

If you need help installing Office 2010, see Install Office 2010 and Activate Office 2010.

Office came pre-installed on my computer

If Office came with your PC, Mac, Laptop, or tablet, look for the product key on the Certificate of Authenticity that came with your computer.

Tip: You may have one certificate of authenticity for Windows and another for Office. Please make sure you’re using the correct certificate of authenticity to retrieve your Office 2010 product key.

A certificate of authenticity for Office 2010 will have the words 'Microsoft Office 2010' on it.

My Office 2010 product key doesn't work

There are several reasons why you might get an error after entering a product key. For example, the product key may have been mistyped or a product key for a different product might have been used.

Are you entering a product key for another Microsoft product?

Most Microsoft products use a 25-character product key. If you own multiple Microsoft products, it’s easy to confuse the keys and use the wrong one. Here are some common things that can happen:

  • Using the product key from a sticker on a PC

    These product keys are normally for Microsoft Windows. Check the sticker for a product name to make sure it’s for the Office product you’re trying to install.

  • Using the product key from an earlier version of Office

    Office product keys aren’t interchangeable between Office versions. For example, you can’t use a Microsoft Office Home and Student 2007 product key if you’re trying to install Microsoft Office Home and Student 2010.

  • Using the product key from an individual program to install a suite

    Office product keys aren’t interchangeable between Office suites and individual programs. For example, you can’t use a Microsoft Word product key to install Microsoft Office Home and Student.

  • Using the product key provided by a school or company

    Schools and companies usually buy a different type of Office license. The product keys they provide to students, teachers, and employees are known as volume license keys. These keys can’t be used for retail Office versions like Home and Student, Home and Business, or Professional.

Did you mistype the product key?

Reading the product key from a label can be difficult. Letters and numbers may look the same.

To avoid typing mistakes, here’s a list of commonly mistyped characters:

  • The letter B and the number 8.

  • The letter G and the number 6.

  • The letter O and the number 0.

  • The letter Q and the number 0.

  • The letters V and V back to back (VV) appear like the letter W.

If you're having trouble reading the characters in your product key, here's an example of what the letters and numbers look like:

Tip: If you bought Office from an online retailer and received a confirmation email, try copying and pasting the product key from this email instead of typing it.

Is your product key still not working?

If your Office product key doesn’t work, or has stopped working, you should contact the seller and request a refund. If you bought a product key separate from the software, it’s very possible the product key was stolen or otherwise fraudulently obtained, and subsequently blocked for use. Unfortunately, there are many dishonest sellers who offer stolen, abused, or otherwise unauthorized Microsoft product keys for sale. Sometimes these product keys are printed on counterfeit labels or cards with a download link to Microsoft software, and sometimes they’re distributed with software media that is unauthorized for resale, such as promotional media, original equipment manufacturer reinstallation media, or other Microsoft program-specific media.

I have my Office 2010 product key but lost the installation disk

If you had a DVD, but can’t find it or your PC doesn’t have a DVD drive, see Download earlier versions of Office at https://www.microsoft.com/software-download/office and use the product key to download and install Office. Use this link ONLY if Office came with a DVD.
