Question

System Specifications:

Device: HP Pavilion Aero 13

Processor: AMD Ryzen 5800U

GPU: AMD Radeon Integrated

OS: Windows 11 Home (Build 26100.7623 / 24H2 Branch)

The Issue: Since the automatic installation of recent Windows 11 security updates (specifically targeting the KB5074109 and KB5077869 sequence), I am experiencing severe, reproducible frame-time stuttering. This is most prevalent during rapid mouse camera rotation in 3D environments. The issue manifests as a "micro-hitch" or "skip" despite maintaining a high average FPS.

Troubleshooting Already Performed (To avoid redundant suggestions):

System Integrity: Ran sfc /scannow and DISM /RestoreHealth in Safe Mode; no permanent corruption found.

Driver Clean-up: Performed clean installation of AMD Adrenalin drivers.

Update Rollback Attempts: Attempted to uninstall KB5074109 and associated servicing stack updates via DISM and WUSA. Encountered "Update is required and cannot be uninstalled" errors, suggesting a permanent shift in the OS servicing branch.

Power Management: Enabled "Ultimate Performance" power plan and set Minimum Processor State to 100% to rule out AMD Core Parking issues.

MPO Toggle: Disabled Multi-Plane Overlay (MPO) via Registry to rule out Desktop Window Manager (DWM) interference.

BIOS/TPM: Investigated fTPM stuttering (common on AMD Ryzen platforms).

Same problem here with a RX580 mouse is lagging.

Answer 2

Hi Jason,

Thanks for reaching out to Microsoft Q&A Forum. I understand you are experiencing stuttering during gameplay on Windows 11 25H2 after installing update KB5077181, specifically when moving the mouse, even after completing an in‑place repair and updating the system.

Please make sure you already tried the Q&A Assist steps. In addition, please try the following.

To help narrow this down a bit:

1. Does this behavior occur with all mice or only a specific mouse model?
2. Are you using any third‑party mouse software or overlays running in the background?

In the meantime, you can try these steps:

1, Check mouse polling rate and enhancements

• Open Settings, go to Bluetooth & devices, then Mouse
• Turn off Enhance pointer precision
• If your mouse has software, temporarily set polling rate to 500 Hz and test again

2, Disable full screen optimizations for the affected game

• Right‑click the game executable
• Select Properties, then Compatibility
• Enable Disable full screen optimizations and apply changes

3, Turn off variable refresh and related graphics features

• Open Settings, go to System, then Display
• Select Graphics, then Default graphics settings
• Turn off Variable refresh rate and Hardware‑accelerated GPU scheduling
• Restart the device

4, Perform a clean boot to rule out background conflicts

• Press Win + R, type msconfig, and press Enter
• On the Services tab, hide all Microsoft services, then select Disable all
• Restart the device and test the game

5, Update or reinstall the display driver manually

• Open Device Manager
• Expand Display adapters
• Right‑click the GPU, uninstall the device, and restart
• Allow Windows Update to reinstall the driver automatically

Answer 3

This issue happened after update KB5077181 when the system is in 25H2. Did in-place repair and got system up to date. Issue still exists. After one day, attempted to rollback but failed. Issue does not happen when video is playing. Only happens when in game with mouse movement.

Answer 4

The provided context only documents one relevant, closely related issue for Windows 11 24H2 performance/stuttering after a security update, and its resolution path.

For Windows 11, version 24H2, there is a known issue where a specific cumulative update caused severe streaming and real‑time performance problems (stuttering, lag, and choppy audio/video) in apps such as OBS and NDI Tools. This issue was later fixed by a subsequent cumulative update.

The documented pattern is:

• A 24H2 cumulative update (OS Build 26100.4946, KB5063878) introduced severe performance problems in real‑time media/graphics workloads.
• The issue was resolved by installing a newer cumulative update (KB5065426), which superseded the problematic one.

Applied to a system already on Windows 11 24H2 (build 26100.x) that cannot roll back specific security updates, the supported remediation pattern from the context is:

1. Ensure the device is fully up to date on Windows Update so that any later cumulative update that supersedes the problematic one is installed.
2. If Windows Update reports “You’re up to date” but the device is stuck on a problematic build, perform an in‑place repair/reinstall of the current Windows 11 version, then reapply updates.

Concretely, based on the documented guidance:

1. Use Windows Update to move to the latest available 24H2 cumulative update
   • Open Settings → Windows Update.
   • Select “Check for updates” repeatedly until no further quality updates are offered.
   • The goal is to install a newer cumulative update that supersedes the one that introduced the stuttering, similar to how KB5065426 fixed the NDI performance regression that KB5063878 caused.
2. If the system is already on the latest offered build but the issue persists, perform a repair install of the current Windows 11 build
   • Go to Settings → System → Recovery.
   • Use the Reinstall/Repair option that keeps apps and data (in‑place repair install of the same Windows 11 edition and version).
   • After reinstall completes, return to Settings → Windows Update and install all pending updates again.
   • This is the same remediation pattern used in the context for Windows 11 25H2 update failures and activation/branch issues: an in‑place reinstall of the same edition and version to reset the servicing baseline, then re‑update.
3. If the device is on an Insider/preview branch (24H2 Release Preview or similar)
   • The context shows that preview channels sometimes pause updates for a period (“Always says You are up to date”), then resume with a newer build.
   • If on a preview channel, remain enrolled and periodically check for a newer build; the stuttering may be addressed in a subsequent preview build, as with the NDI streaming issue.

If the stuttering was introduced by a specific 24H2 cumulative update and that update is marked as non‑removable (servicing baseline), the supported and documented paths in the context are:

• Move forward to a newer cumulative update that contains the fix.
• If blocked or corrupted, perform an in‑place repair/reinstall of the same Windows 11 version, then update again.
