That sinking feeling when you realize you saved over a version of a file you need or unwittingly lost some vital information in a recent document revision is all too familiar to many.

Restore Files from Microsoft OneDrive, Office, or Windows

Before we run through your options here, you should know that to recover previous versions of files from Microsoft’s Windows or Office suite, you need a backup to draw them from. If you haven’t set up a backup in Windows or with OneDrive, then you are likely out of luck.

If you use Microsoft’s OneDrive cloud storage service to save your files online, then it’s easy to recover previous versions. Here’s how:

1. Open OneDrive in your browser.
2. Find the file you want and right-click on it.
3. Choose Version history from the drop-down list.
4. Click the ellipses (…) or arrow next to the version you want and choose Restore.
