Windows 11 24H2/25H2 System Freeze After January 2026 Updates – Lenovo ThinkPad G2
Dear Microsoft Support Team,
We would like to raise a high-priority technical support case regarding a stability issue observed after installing the January 2026 cumulative updates on our Windows 11 devices.
Environment Details:
- Device Model: Lenovo ThinkPad G2 (multiple units)
- OS Versions: Windows 11 24H2 and 25H2
- Update Installed: January 2026 Patch Tuesday cumulative update (KB number can be provided)
- Deployment Method: WSUS / Intune / Windows Update (specify accordingly)
- BIOS Version: (Installed Latest available from Lenovo)
Issue Description: After installing the January 2026 cumulative updates, devices intermittently experience a complete system freeze. The system becomes fully unresponsive:
- Mouse and keyboard input stop responding
- No BSOD is displayed
- Task Manager cannot be opened
- System recovery is only possible via hard reboot (power button)
Frequency: The issue occurs randomly, both during active use and idle state. Multiple users across our environment are impacted.
Troubleshooting Performed:
- Reinstalled OEM-certified Lenovo display drivers
- Disabled Fast Startup
- Ran SFC and DISM health checks (no integrity violations)
- Updated BIOS to latest version
- Setting power idle mode, then work normally
Request:
- Please confirm whether this is a known global issue under investigation.
- Advise if any hotfix, Known Issue Rollback (KIR), or registry-based mitigation is available.
- Provide guidance on additional diagnostic logging required at kernel or driver level.
- Confirm whether crash dump analysis is recommended for this scenario.
We are prepared to provide additional diagnostic logs, memory dumps, or reproduction steps upon request.
Kindly treat this as a priority case due to multi-user impact in a production environment.
Thank you for your support.

The same issue is occurring in my case as well. I currently have 11 Lenovo ThinkPad E15 Gen 2 units that are experiencing this problem.
I have the same issue on a lot of different Lenovo models.
These models have been updated with the latest drivers, BIOS, and Windows Updates. All are on Windows 11 25H2:
T14s Gen 6
T14s Gen 5
ThinkPad X1 Carbon Gen 13
But still, the same random freeze occurs.
Is there any new information on this issue?
Is it solved in Februari 2026 cumulative update?
February 10 update KB5077181 doesn't help ... unfortunately.
Thanks for the update.
And I can confim that february updates does not resolve the problem.
Any other leads on this subject?
Does Lenovo have anything to say about this?
Microsoft released two emergency updates to address related January issues. While they primarily target cloud storage and boot failures, they contain cumulative kernel stability improvements:
KB5077744: Released January 17 (specifically for 24H2/25H2 stability).
KB5078127: Released January 24 (targets unresponsive apps and Task Manager bugs).
These often must be downloaded manually from the Microsoft Update Catalog if they don't appear in your standard Windows Update list.
Thanks
Hey, both are included in February 10 update KB5077181 and that didn't help. More and more I am thinking it can be a configuration issue, January update KB5074109 maybe misconfigured something and even uninstalling that update didn't help back in January.
Same here with Lenovo ThinkPad E15 gen 2 (Intel), everything is up-to-date. Sometimes it happens 2-3 times a day, sometimes there is a day or two without a problem.
I have experienced this issue on 11 Lenovo thinkpad E15 Gen 2's. Only work around has been to disable all power saving / sleep / hibernation options
Please confirm if this is a known global issue under investigation related to the January 2026 updates.
The same problem occurs on Lenovo ThinkPad T14 Gen 5 AMD devices, model 21MCCTO1WW.
I too have the same issue. I have more than 15 laptops. have tried updating the bios, usb c power drivers etc, but to no avail. Microsoft kindly resolve the same at the earliest.
