Question details
The user is unable to log into OneDrive because clicking the sign-in button does nothing and the credential window does not appear.
- Product
- Microsoft OneDrive
- Device & OS
- Windows
- Scenario
- Attempting to sign in to the desktop version of OneDrive after a password change, reset, or fresh installation.
- Observed behavior
- The sign-in button is unresponsive, and no login prompt or folder-selection window opens, leaving the user unable to authenticate or sync files.
Before modifying system registries, verify that your internet connection is stable and temporarily disable any third-party antivirus or VPN software to rule out basic network interference.
Clear OneDrive Registry Configuration and Reinstall
Deleting corrupted registry keys and performing a clean installation often resolves unresponsive sign-in windows.
Corrupted local configurations can prevent the OneDrive login interface from loading. Clearing these configurations via the Registry Editor forces the app to rebuild its settings.
Press Windows + R to open the Run dialog box, type 'regedit', and press Enter to launch the Registry Editor.
Navigate to the following path: HKEY_CURRENT_USER\Software\Microsoft\.
Find the 'OneDrive' folder within the Microsoft directory, right-click it, and select 'Delete'.
Open the Control Panel, uninstall your current version of OneDrive, and then download and install the latest version from Microsoft's official website.
Unblock Required Microsoft Domains in DNS or Firewall
Network filters or organizational policies might block required Microsoft domains, preventing the login window from authenticating.

Frequently Asked Questions
Why does the OneDrive sign-in window disappear immediately?
This typically happens due to a corrupted local cache, blocked network domains, or restrictive firewall settings that prevent the application from securely reaching Microsoft's authentication servers.
Will deleting the OneDrive registry key delete my files?
No, deleting the OneDrive folder in the Windows Registry Editor only resets the application's configuration and login state. Your actual files stored on your computer's hard drive or in the cloud will remain completely unaffected.
What network domains need to be whitelisted for OneDrive to work?
OneDrive requires unrestricted access to several key Microsoft domains to authenticate and sync correctly, primarily '1drv.com', 'onedrive.live.com', and 'login.microsoftonline.com'. Make sure these are allowed through your firewall and DNS filters.
