OneDrive is built into most Windows 10 installations. Search for OneDrive and open it; if it is missing, install the current sync app from Microsoft. Windows 10 support ended October 14, 2025, so upgrading to Windows 11 should be part of your security plan.
How to do it
Step 1: Look for the existing app
Open Start, type OneDrive, and select Microsoft OneDrive if it appears.
Step 2: Download OneDrive if missing
Visit Microsoft’s official OneDrive download page and download the Windows installer. Avoid third-party download sites.
Step 3: Install the sync app
Run OneDriveSetup and wait for it to finish. Then open OneDrive from Start.
Step 4: Connect your account
Enter the Microsoft personal, work, or school account you want to use and follow the sign-in prompts.
Step 5: Review sync and backup choices
Confirm the OneDrive folder location, select folders, and review backup for Desktop, Documents, and Pictures. Verify the cloud icon shows a completed sync.
What happens next
A OneDrive folder appears in File Explorer and begins syncing the selected content. Confirm files are fully uploaded before relying on them as a cloud copy.
Tips and troubleshooting
- Installing OneDrive does not extend Windows 10 security support.
- Keep another backup of irreplaceable data; sync is not a complete backup strategy.
- Online-only files require internet access before first use.
- Check account storage if syncing stops.
