What happens if I uninstall OneDrive?
If it’s uninstalled, your OneDrive folder will stop syncing, but any files or data you have in OneDrive will still be available when you sign in at OneDrive.com.
Should you uninstall OneDrive?
By disabling OneDrive, you’re gaining back control of your own files, rather than storing them on a Microsoft-based server. This will have more of a noticeable impact on low-resource PCs, so disabling OneDrive could be a good way to claw back some CPU and RAM usage.
