Windows 11 24H2 blocked on PCs with code-obfuscation driver BSODs

Microsoft has introduced a new Windows 11 24H2 safeguard hold for systems running security or enterprise software using SenseShield Technology’s sprotect.sys driver.

This upgrade block will prevent users from upgrading to the latest Windows 11 version because the driver can crash and trigger blue or black screen of death (BSOD) errors, and it impacts systems with any sprotect.sys driver version.

“Microsoft is working with SenseShield Technology Co on a compatibility issue between Windows 11, version 24H2 and the sprotect.sys driver,” the company said in a new update to the Windows release health dashboard.

“The sprotect.sys driver provides encryption protection and is used by specialized security software and enterprise solutions. This driver can be automatically introduced into a system as part of the installation process of many different applications.”

To prevent these incompatibility issues on affected Windows 11 24H2 PCs, Microsoft added an upgrade hold to block the Windows 11 2024 Update from being offered via Windows Update.

“SenseShield is currently investigating this issue. Microsoft is collaborating with SenseShield, and we will provide more information when it is available,” Microsoft said.
