Microsoft says that Windows 10 updates released in late September are causing Windows taskbar flicker issues and app instability.
"After installing updates released September 20, 2022 or later, taskbar elements might flicker and cause system instability," Microsoft said in a new issue added to the Windows health dashboard on Friday.
Microsoft has addressed the issue via Known Issue Rollback, a Windows capability that reverts faulty Windows non-security fixes pushed via Windows Update.
You can download this Rollback Group Policy from here for all impacted Windows 10 versions.
To deploy the Known Issue Rollback, you must go to the Local Computer Policy or the Domain policy on your domain controller using the Group Policy Editor to choose the Windows version you want to target.
Last month, Microsoft issued another emergency fix via Known Issue Rollback to address another issue triggering errors and causing the taskbar and desktop to disappear on Windows 10 systems.
