Microsoft has informed Windows 10 users that their devices are not eligible for an upgrade to Windows 11 due to system requirements and recommends transitioning to a new PC with Windows 11. A new compatibility issue has arisen with the sprotect.sys driver, causing system freezes and errors on Windows 11 version 24H2, leading Microsoft to impose a compatibility hold on affected devices. This hold prevents these devices from being prompted to install Windows 11, version 24H2. Users with impacted devices will see a notification on the Windows Update page indicating no immediate action is required. IT administrators can monitor the issue using safeguard ID 56318982. Microsoft advises against forcing the update if the system is incompatible and is working with SenseShield Technology Co. to resolve the issue.
