If your PC suddenly feels like it aged five years overnight, stop checking your GPU temperatures. The culprit isn’t your hardware; it’s likely the recent Windows 11 update. The January and February 2026 rollout, specifically Windows 11 KB5074109, has triggered a wave of complaints regarding Nvidia performance issues.
Users running high-end rigs with RTX 4090s and the new RTX 5080s are reporting massive framerate drops, stuttering, and system instability. While Microsoft hasn't fully detailed the cause, the community has already identified the solution.
Here is exactly how to fix the slowdowns caused by Windows 11 KB5074109 and get your system back to normal.
Immediate Fix: Uninstalling KB5074109
The most effective way to restore your Windows 11 KB5074109 Nvidia performance is to remove the update entirely. This is the solution confirmed by the majority of affected users on Reddit and TechSpot forums.
Since this update often installs automatically, many users don’t realize it’s running until games become unplayable.
Step-by-Step Uninstall Guide
Open your Settings menu.
Navigate to Windows Update and click on Update history.
Scroll down to the bottom and select Uninstall updates.
Locate Security Update for Microsoft Windows (KB5074109) in the list.
Click Uninstall and confirm the action.
Restart your PC immediately.
Once the system reboots, your framerates should return to baseline levels.
Important: After uninstalling, go back to Windows Update and click Pause updates. If you don’t, Windows will likely try to reinstall the patch overnight, bringing the stuttering right back. Keep updates paused until Microsoft releases a superseded patch in the next cycle.
Symptoms: How KB5074109 Impacts Nvidia Performance

This isn't a minor degradation. The Windows 11 KB5074109 Nvidia performance hit is drastic enough to make flagship hardware struggle with titles that ran perfectly a week ago.
The data extracted from user reports paints a grim picture. In Warhammer 3, users saw framerates tank from a stable 120 FPS down to a stuttery 90 FPS. Fortnite players on RTX 4050 laptops reported drops from 160 FPS to an unplayable 5 FPS.
Specific Hardware Issues
It affects the entire spectrum of modern hardware:
GPUs: RTX 3090, 4090, 5070 Ti, and 5080.
CPUs: Ryzen 7 7800X3D, Ryzen 9 9950X3D, and Ryzen 680M iGPUs.
The symptoms go beyond low numbers. Users describe severe "stuttering," where the game freezes for micro-seconds, and random visual glitches. Some report a "red flicker" or flash before windows render, while others are seeing random single-frame black screens.
Troubleshooting this has been frustrating because standard stress tests like 3DMark and Furmark show normal power draw and temperatures. The hardware is physically fine; the software layer between the OS and the GPU is broken.
Advanced Workarounds for KB5074109
If you work in a corporate environment where you cannot uninstall security updates, or if the update reappears, there are user-tested workarounds. These don't solve the root cause like an uninstall does, but they mitigate the Windows 11 KB5074109 Nvidia performance degradation.
Disable Shader Cache
One Reddit user, Pesanur, found that the update interferes with how shaders are cached and read.
Open the Nvidia Control Panel.
Navigate to Manage 3D Settings.
Locate Shader Cache Size and set it to Disabled.
Restart your computer.
This may increase load times in some games, but it often stops the micro-stuttering caused by corrupted cache interactions introduced by the update.
Reset Virtual Memory (Page File)
Another conflict appears to stem from memory management. User CSOptimusP discovered that the update breaks Nvidia App and GeForce NOW if the page file is manually set.
Type "Advanced System Settings" in the Windows search bar.
Go to the Advanced tab and click Settings under Performance.
Go to the Advanced tab again and click Change under Virtual Memory.
Check the box for "Automatically manage paging file size for all drives."
Restart.
This has resolved launch failures for several users who previously manually tuned their RAM settings.
Why is Windows 11 KB5074109 Breaking Games?

The finger-pointing has already started. Nvidia has officially acknowledged the complaints but explicitly stated that this is an operating system issue, not a driver failure. This aligns with user experiences where using DDU (Display Driver Uninstaller) to wipe and reinstall Nvidia drivers makes absolutely no difference.
This update was intended to include over 100 security fixes and patches for "AI PC" NPU integration. It seems that the changes made to accommodate new NPU architectures or security protocols have introduced latency or conflicts in the graphics pipeline.
Because KB5074109 is a mandatory security update, it has a high adoption rate, which explains why the reports exploded so quickly in January and February 2026.
Non-Gaming Issues: Azure and USB
While Windows 11 KB5074109 Nvidia performance in gaming grabs the headlines, this patch is causing functional damage elsewhere.
Azure Virtual Desktop (AVD) Failures
System administrators are seeing error code 0x8008005 when attempting to connect to Azure Virtual Desktops. This effectively locks remote workers out of their cloud workstations. The only current fix for this enterprise-level issue is the same as the consumer fix: rolling back the update.
Outlook and USB Bugs
The instability extends to basic peripherals and productivity apps:
USB Formatting: Users are unable to format flash drives to FAT32.
Outlook: The application freezes or fails to launch entirely.
Reboot Loops: A minority of machines enter a reboot loop immediately after the update installs, requiring a System Restore point to recover.
Determining If You Are Affected

If you suspect your system is suffering from the Windows 11 KB5074109 Nvidia performance bug, look for these specific behaviors:
Vulkan API Crashes: Games running on Vulkan (like Rainbow Six Siege or Red Dead Redemption 2) may freeze the entire PC, requiring a hard reset.
Visual Artifacts: Look for strange shadow artifacts or texture pop-in that wasn't there before.
Visual Studio / Coding Lag: Even non-gaming GPU acceleration is hit. Developers using GPU-accelerated IDEs report typing lag and render delays.
Many users initially wasted money buying new DisplayPort cables or monitors, assuming their hardware had failed. Before spending money on hardware, check your Windows version number.
Conclusion
The state of Windows updates in 2026 remains volatile. While Microsoft aims to secure the platform with patches like KB5074109, the lack of quality control for high-performance hardware continues to drive a wedge between the OS and the enthusiast community. Some users in the discussion threads have even migrated to Linux distributions like Bazzite to escape these recurring performance penalties, despite the slower load times on NTFS partitions.
For now, if you value a stutter-free experience, keep KB5074109 off your machine. Pause your updates and wait for the next iteration to clear the pipeline.
Frequently Asked Questions
Is it safe to uninstall Windows update KB5074109?
Yes, for most home users, it is safe to uninstall to restore performance. However, because it is a security update, your system will temporarily lack the latest security definitions until a fixed patch is released.
Does KB5074109 affect AMD Radeon or Intel GPUs?
While the majority of reports focus on Windows 11 KB5074109 Nvidia performance, some users with AMD Ryzen 680M integrated graphics have also reported framerate drops. The issue appears to be how Windows handles graphics rendering, affecting multiple vendors.
Why does Windows keep reinstalling KB5074109 after I uninstall it?
Windows 11 prioritizes security updates and will attempt to reinstall them automatically. You must go to Windows Update settings and select "Pause for 1 week" (or longer) immediately after uninstalling to prevent the loop.
Will updating my Nvidia drivers fix the stuttering?
No. Nvidia has confirmed the issue lies within the Windows update, not the driver. Reinstalling drivers or using DDU will not solve the lag unless you also remove the Windows patch.
When will Microsoft fix the issues with KB5074109?
Microsoft usually addresses these bugs in the following month's "Patch Tuesday" or via an optional "Preview" update later in the month. Until then, no official hotfix exists other than removal.
