June Windows 10 updates cause new system problems
Microsoft recognized a new known issue that led to the critical process of the LSASS system (Local Security Authority Subsystem Service) and forced reboots on some Windows 10 devices.
LSASS is responsible for enforcing security policies on Windows systems and is used by the system to add entries to the security log, in addition to handling user logins, password changes and creating access tokens.
When LSASS fails, the user immediately loses access to all accounts available on the machine, an error is displayed and the machine is forced to restart.
Devices running Windows 10 1809 or later are affected
Microsoft explains that the Local Security Authority Subsystem Service (LSASS) file (lsass.exe) may fail on some devices with the error message:
The known issue was added today by Microsoft in the entries for KB4557957 and KB4560960 cumulative updates published as part of this month’s “Patch Tuesday” on June 9, 2020, as well as about entries for KB4567512 and KB4567523 optional updates fixing the previous edition causing printing problems.
While these updates can only be applied to Windows 10 versions 1903 or later, users have also reported having the same issue with devices running fully updated installations of Windows 10, version 1809.
Another user said he was having random reboots after his notebook running Windows 10 1809 Enterprise was updated.
Microsoft has not yet formally acknowledged the issues (no new support documents have been published or new known issues have been added to the Windows 10 health panel to date) and an official fix for this issue is not yet available.
However, as the company explains, the developers are working on an update to be provided to affected customers as part of an upcoming update.
Although an official fix is not available, users who are unable to use their devices due to the continued failure of LSASS can get rid of the problem by uninstalling the June 2020 cumulative updates.
Before uninstalling the two cumulative updates, you must first know that you are also removing the update that resolves security issues that affect your Windows 10 device.
Microsoft says in the details of the two updates (1, 2) that they can be removed “by selecting View installed updates in the Programs and Features Control Panel”.
If you want to remove such updates, do the following:
- Click the Start button or use Search on the Windows desktop, enter update history and select View your update history.
- In the Settings / View update history dialog window, select Uninstall updates.
- In the Installed updates dialog window, locate and select KB4560960 or KB4557957 and select the Uninstall button.
- Restart your device.
Ready your computer with Windows 10 should stop with random reboots. Now we can only hope that Microsoft brings an update that corrects the problem and, most importantly, does not cause others.
