The company posted on its tech support forum that OneDrive support on older Windows versions would end on March 1, 2022. The post says, “In order to focus resources on new technologies and operating systems, and to provide users with the most up-to-date and secure experience, beginning January 1, 2022, updates will no longer be provided for the OneDrive desktop application on your personal Windows 7, 8, and 8.1 devices. Personal OneDrive desktop applications running on these operating systems will stop syncing to the cloud on March 1, 2022.”
This isn’t a case of Microsoft no longer offering updates for OneDrive on older operating systems, as the support post says that “After March 1, 2022, your personal files will no longer sync and should be uploaded/accessed directly on OneDrive for web.”
While you can use OneDrive on the web, as mentioned by Microsoft, your files won’t sync automatically, so you’ll need to upload them manually, which will become tedious rather quickly if you’re making a lot of changes to your files and folders.
The best course of action is probably to update to Windows 10 or Windows 11. However, you also have the option of switching to another cloud storage solution if you’re really determined to keep using the older version of Windows.
