Windows 11 24H2/25H2 System Freeze After January 2026 Updates – Lenovo ThinkPad G2

We have the same issue with multiple Lenovo ThinkPad E14 Gen 2 across the organization (more than 10 cases reported). All of them are on Windows 11 25H2 with the latest updates and drivers. What I noticed is that it happened more frequently on the battery and when the laptop is left unattended, even for 2 minutes. I assume the freeze occurs when the laptop is trying to enter sleep state or turn the screen off on timeout due to inactivity. I tried to uninstall the January 2026 update (KB5074109), install out-of-band update KB5077744, and finally, when the February 2026 update KB5077181 was released, I installed it over KB5074109 - none of this worked. What worked well: a system restore to a point before the KB5074109, but unfortunately, most laptops don't have such a restore point.

Additionally, I installed the February 2026 update on the laptop, which does not have the January 2026 update - no freezes within 1 day, but I keep watching.

The issue started appearing just after the January 2026 update, happening randomly, and only on ThinkPad E14 laptops. We have other laptop models - they are working fine.

I am ready to collect/provide any logs, try workarounds, and support in any way to find the solution.

Asking Microsoft to pay attention to this issue.
