Microsoft has revealed this week that the bug causing Windows 10 version 20H2 to get an unexpected restart message when opening dialog windows listing users has become fixed.
In addition, the company says the upgrade block preventing devices potentially affected by the problem has also been lifted, so these computers are now able to upgrade to Windows 10 version 20H2 with the typical official channels.
“After updating to Windows 10, version 20H2, you may get the error in LSASS.exe with the text “Your PC will automatically restart in one minute” when interacting with any dialog window that lists users, for instance accessing the sign-in options settings app page or even the users folder from our user and groups MMC snap-in. This issue only affects devices in which any of the local built-in accounts have been renamed, such as Administrator or Guest. You could also receive an error within the Application Event log with Event ID 1015 that LSASS.EXE failed with status code C0000374. C0000374 is related to heap corruption,” Microsoft originally explained.
Windows Server version 20H2 affected too
The organization says the problem affected both Windows 10 version 20H2 and Windows Server 20H2, also it could take up to Twenty four hours until the safeguard hold is removed all devices and also the update is therefore allowed.
As for that which was causing the issue, the company says it all comes down to duplicated user accounts created during the update process to Windows 10 version 20H2.
“This concern is brought on by duplicate built-in user accounts being made up of the same security identifiers (SIDs) and relative identifiers (RIDs) throughout the update to Windows 10, version 20H2. SIDs and RIDs for built-in user accounts are well-known as documented here and should be unique on the given device,” the organization says.
If you’re using Windows Update for Business, the latest version packing the fix should be available.
