Deactivate an Office 365 install

Your browser does not support video. Install Microsoft Silverlight, Adobe Flash Player, or Internet Explorer 9.

If you want to install Office on another computer but you've run out of installs, you'll need to deactivate one.

  1. Go to, and sign in with your Microsoft account. This is the email address and password you associated with your copy of Office.

  2. Choose Install.

  3. On the Install page, choose Deactivate Install next to the name of the computer or tablet that has the install you want to remove.

  4. Choose Deactivate to confirm that you want to deactivate this install.

Note: After you deactivate an install, Office runs in read-only mode on that computer or tablet. That means you can view and print documents, but you can't edit or create new ones.

With an Office 365 Home subscription, you can install Office on up to 5 PCs or Macs, 5 tablets, and 5 smartphones.

If you’ve used up all your installs and want to add another, you’ll need to deactivate one of the existing installs.

Here you can see all of my PC and Mac installs are being used.

My son wants to install Office on his new laptop, so I’ll need to deactivate one of these installs first.

My wife has volunteered to give up one of her installs, so on the Install page, I find the computer, and choose Deactivate Install.

A reminder appears to let me know that deactivating Office doesn’t uninstall it--it just puts it into read-only mode.

All the documents are still there, and my wife can view or print them. She just can’t edit them or create new ones on that computer.

She can still use the full functionality of Office programs on her other computer.

Back on My Account page, I choose Share Office 365, and now when I invite my son to share my subscription, he’ll have an Office install available to use.
