Windows 11 22H2 Patch causes freezing issues on AMD Ryzen PCs
The Patch Tuesday for December (KB5021255) is apparently causing headaches for users with AMD Ryzen PCs. This update is a follow-up to the November Patch Tuesday update (KB50119980) that fixed the security vulnerability related to the Spectre Variant 2 on most AMD processors.
Reddit user Thomsen48 exclaimed that this issue was already present in November’s Patch Tuesday (KB5019980). The user wrote that the freezing issues appeared on their Ryzen 5 4600GE systems with the November update which they had to remove. Systems with the same Windows 11 22H2 operating systems powered by Intel processors are not affected.
Another Reddit user named BabyMayCry used the same thread to post a similar problem on its Ryzen 5900X systems where the system would randomly freeze, then unfreeze after 10-20 seconds. When investigating processes in Task Manager this user discovered the System Interrupts process locked at 100% along with Autopilot.dll WIL errors reported in the Event Viewer.
Microsoft still hasn’t confirmed issues with the December Patch Tuesday update.
