Hi Ray,
Before uninstalling OneDrive, please do the following:
Step 1: Restore the files from the OneDrive cloud.
Please click on the OneDrive icon in the notification area. In the OneDrive flyout window, click the gear icon and select Settings.
In the Sync and Backup tab, expand "Advanced settings". Under "Files On-Demand", click "Download all files". Selecting this option downloads all files from the cloud to your device.
Step 2: Stop folder backups in OneDrive
Once done, you can stop folder backups. See the section "Stop folder backup in OneDrive" at this link → Back up your folders with OneDrive | Microsoft Support.
After completing the above two methods, you may uninstall OneDrive if you don't plan to use it.
