BUG ALERT: Microsoft Issues Warning To Millions Of Windows 10 Users

Microsoft has issued a warning to Windows 10 users following the discovery of a bug in version 1903. The bug, which impacts the OS’ Remote Access Connection Manager, has the potential to affect tens of millions of users. Here’s what you need to know (and how to fix it.)

Microsoft recently acknowledged the existence of a major bug in Windows 10 May 2019 Update’s latest build (KB4501375). As reported by Windows Latest, the bug breaks down the Remote Access Connection Manager service (aka RASMAN) which can seriously hamper VPN services.

According to Microsoft, the issue only affects version 1903 of Windows 10 which has well over 50 million active users worldwide. Here’s the info from Microsoft’s support page:

The Remote Access Connection Manager (RASMAN) service may stop working and you may receive the error “0xc0000005” on devices where the diagnostic data level is manually configured to the non-default setting of 0. You may also receive an error in the Application section of Windows Logs in Event Viewer with Event ID 1000 referencing “svchost.exe_RasMan” and “rasman.dll”.

This issue only occurs when a VPN profile is configured as an Always On VPN (AOVPN) connection with or without device tunnel. This does not affect manual only VPN profiles or connections.

The TLDR version: if you installed the very latest version of Windows 10, your VPN connection may have stopped working. Depending on what you use your VPN for (*cough* piracy *cough*) this could be a pretty big deal.

Microsoft is working on a resolution which should be available in late July. In the meantime, you can simply roll back Windows 10 to the previous update. To do this, simply click the Start button, then select Settings, Update & Security, Windows Update, View update history and Uninstall updates. Select the update you want to remove, then select Uninstall.
