Reinstalling OneDrive on Windows 10 can help fix sync issues and other glitches with the app. First, you’ll need to uninstall OneDrive, then reinstall it from the Microsoft website. This brief guide will walk you through the process step by step.
Check your files before reinstalling
Open OneDrive on the web with the correct account and verify that important recent files are there. Copy unsynced local files to a separate safe location. Online-only placeholders are not complete local backups. Do not delete the OneDrive folder as an uninstall step.
Read the actual sync error first: storage quotas, permissions, account problems and file-name conflicts will not necessarily be fixed by reinstalling.
How to Reinstall OneDrive on Windows 10
Reinstalling OneDrive on Windows 10 involves uninstalling the current version of OneDrive and then downloading a fresh copy from Microsoft’s official site. Follow these steps for a seamless reinstall.
Step 1: Open Settings
First, click on the Start menu and select "Settings."
In the Settings menu, you’ll find various system settings. This is where you’ll need to go to start the uninstallation process.
Step 2: Navigate to Apps
Next, click on "Apps" to open the Apps & features settings.
This section lists all the applications installed on your computer. You’ll use it to find and uninstall OneDrive.
Step 3: Find OneDrive
Scroll down the list until you find "Microsoft OneDrive." Click on it.
You’ll see OneDrive along with other apps you’ve installed. Clicking on it will give you the option to uninstall the app.
Step 4: Uninstall OneDrive
Click the "Uninstall" button and follow the on-screen prompts.
The system will ask for confirmation before proceeding. Confirm to remove OneDrive from your system.
Step 5: Download OneDrive
Go to the Microsoft OneDrive download page and click on "Download OneDrive."
This will download the latest version of OneDrive to your computer. Ensure you get it from Microsoft’s official site to avoid any malware issues.
Step 6: Install OneDrive
Open the downloaded file and follow the installation prompts.
The installation process is straightforward, guiding you through each step to reinstall OneDrive on your computer.
Start the installed sync app, sign in to the same account, and review the proposed folder location and folder-backup choices. Let it reconcile files, then check the cloud icon for errors and compare a recent file with its web copy. Reinstallation may repair the app but does not guarantee every sync issue is resolved.
Tips for Reinstalling OneDrive on Windows 10

- Close Other Applications: To avoid conflicts, close other applications while reinstalling OneDrive.

Frequently Asked Questions
How do I know if OneDrive is successfully uninstalled?
You can check if OneDrive is uninstalled by navigating back to the Apps & features list in Settings. If OneDrive is no longer listed, it’s been successfully uninstalled.
Will I lose my files if I reinstall OneDrive?
Uninstalling the sync app does not itself delete files already stored in OneDrive online. However, unsynced edits may exist only on this PC, so protect them first. Deleting files inside an actively synced folder is different and can delete their cloud copies.
Can I reinstall OneDrive without an internet connection?
You need connectivity to obtain the current installer if you do not already have it, and to sign in and sync. Having an installer saved locally does not make cloud files available offline.
What if I encounter issues during the installation process?
If you face issues, try restarting your computer and repeating the installation process. Ensure no other applications interfere with the installation.
Is it safe to download OneDrive from third-party websites?
No, always download OneDrive from the official Microsoft website to avoid malware and ensure you get the latest version.

Conclusion
Reinstalling OneDrive on Windows 10 is a straightforward process that can solve many common issues. By following the steps outlined above, you can ensure a clean reinstall of the app. Backing up files and ensuring your system is updated are crucial steps to avoid any complications.
Use the desktop sync application, not a Store viewer app that does not perform file synchronization. Microsoft’s OneDrive reinstall instructions identify the correct application and download path. If errors continue, troubleshoot the specific message rather than repeatedly reinstalling.
