Hello Julie,
Thanks for sharing all the details — I know how stressful this must be, especially when your work depends on reliable access to cloud services. You’re right to be cautious about a full system wipe. Based on what you’ve described, the issue likely stems from the recent Windows 11 update (KB5070773), which has caused similar web access problems for others, even on Microsoft platforms like SharePoint and 365 Admin.
Let’s try a few targeted fixes that have helped others:
- Disable HTTP/3: In Registry Editor, add a DWORD called EnableHttp3 and set it to 0, then restart.
- Turn off Secure DNS: In Edge, Chrome, and Firefox, go to privacy settings and disable “Use secure DNS.”
- Reset your network stack: Run these commands in Command Prompt (Admin): netsh winsock reset, netsh int ip reset, ipconfig /release, ipconfig /renew, ipconfig /flushdns
- Check proxy/VPN settings: Make sure proxy is off and no VPN remnants are active.
- Force IPv4: Disable IPv6 in your network adapter settings.
If that doesn’t help, try manually reinstalling the update from the Microsoft Update Catalog — search for KB5070773 and install the correct version.
