STATUS_GRAPHICS_PRESENT_OCCLUDED 0XC01E0006 Fix

1. Disable Fullscreen Optimizations (most common fix)

This error happens most often in Windows 10 and 11 when a game or app uses fullscreen optimizations. The system tries to overlay the game with the desktop compositor, and if something else (like a notification or another window) covers the game window, the driver reports occlusion and stops rendering. The result is the error 0XC01E0006.

Here's the fix that works 9 out of 10 times:

1. Right-click the shortcut or executable for the game or app that crashes.
2. Select Properties from the context menu.
3. Go to the Compatibility tab.
4. Under the Settings section, check the box that says Disable fullscreen optimizations.
5. Click Apply, then OK.
6. Launch the game again. You should see the game run in exclusive fullscreen mode, and the error should be gone.

Why this works: With fullscreen optimizations disabled, Windows stops trying to treat the game as a composited window. The graphics driver gets exclusive access to the screen buffer, so nothing else can occlude it. No occlusion, no error.

2. Update Your Graphics Driver

If disabling fullscreen optimizations didn't fix it, the next suspect is an outdated or buggy graphics driver. I've seen this error with older Intel HD Graphics drivers especially, but it can happen with NVIDIA and AMD too. Driver bugs can cause the Desktop Window Manager to incorrectly report occlusion even when nothing is covering the window.

Do this:

1. Press Win + X and select Device Manager.
2. Expand Display adapters.
3. Right-click your graphics card (it might say Intel, NVIDIA, or AMD) and choose Update driver.
4. Select Search automatically for drivers.
5. Let Windows search. If it finds a new driver, install it and restart your computer. If it says you're up to date, go to step 6.
6. Go to the manufacturer's website (Intel.com, NVIDIA.com, or AMD.com) and download the latest driver for your exact model.
7. Run the installer. Choose Clean Installation if offered (this removes old driver files that might be corrupt).
8. Restart your PC.

After updating, test the game again. In my experience, Intel users have the most trouble with this error, especially on Windows 11. If you're using a laptop with Intel integrated graphics, make sure you also check for a BIOS update from your laptop manufacturer — sometimes the fix is on the system board side.

3. Run the App in Windowed Mode

If the first two fixes don't work, the problem might be a specific application that just doesn't like fullscreen mode at all. This is common with older games or niche productivity software. Forcing windowed mode bypasses the occlusion check entirely because windowed apps don't trigger the fullscreen optimization code path.

Here's how to force windowed mode:

1. Right-click the shortcut or executable of the problematic app.
2. Select Properties.
3. Go to the Shortcut tab.
4. In the Target field, add -windowed or -w at the end, outside the quotes. So if the target is "C:\Games\game.exe", change it to "C:\Games\game.exe" -windowed.
5. Click Apply and OK.
6. Launch the app.

If the game supports a borderless window option in its video settings, use that instead. It gives you the look of fullscreen without the occlusion problem. Some games have a specific launch option in their launcher (like Steam) set the launch option to -windowed -noborder.

One more thing: if you're using multiple monitors, check that the app isn't spanning across both monitors. That can cause the Desktop Window Manager to get confused and report occlusion. Set the app to only use one display. You can do this by pressing Win + Shift + Arrow key to move the window to a single monitor.

Quick-Reference Summary

That's it. Try these three things in order, and you'll almost certainly kill that 0XC01E0006 error. If none of them work, you might have a deeper system corruption — then run an SFC scan (sfc /scannow in an admin command prompt) and check your event log for more clues. But honestly, for occlusion errors, the fullscreen optimization toggle is the real hero.
