What's this error about?
You're watching a video, playing a game, or using a media app — then boom. Error code 0XC026250A pops up. It means a program tried to set up copy protection on your display, but it passed a bad pointer (a memory address) to Windows. This is almost always a driver-level issue, not your hardware dying.
I've seen this most on Windows 10 and 11 with external monitors or TVs connected over HDMI. It's common when you use apps like Netflix, Hulu, or some games that use HDCP (High-bandwidth Digital Content Protection).
Fix 1: Reboot and update your graphics driver (60 seconds)
Start here. Nine times out of ten, a fresh driver or a simple reboot clears this up.
- Restart your PC completely — not sleep, not hibernate. Click Start, then Power, then Restart.
- After it restarts, right-click the Start button and pick Device Manager.
- Expand Display adapters. You'll see something like NVIDIA GeForce RTX 3060 or Intel UHD Graphics 630.
- Right-click your graphics card and choose Update driver.
- Pick Search automatically for drivers. Windows will check online. If it finds a newer driver, it'll install it.
- After it's done, restart again. Now test if the error went away.
What you should see: Device Manager should show your driver version change after the update. If it says "The best drivers for your device are already installed" — don't stop there. Go to Fix 2.
Fix 2: Roll back a recent driver update (5 minutes)
Sometimes a new driver introduces a bug. I've had this happen with NVIDIA's Game Ready drivers on version 551.86 and later. The fix is to roll back to the previous one.
- Open Device Manager again (right-click Start > Device Manager).
- Expand Display adapters, right-click your GPU, and choose Properties.
- Go to the Driver tab. Look for the Roll Back Driver button. If it's grayed out, skip to Fix 3 — there's no older driver on your system.
- Click Roll Back Driver. Windows will ask why. Pick whatever, like "Apps were crashing." Then click Yes.
- Restart your PC when prompted.
- Test again. Does the 0XC026250A error still show? If it does, move on to Fix 3.
What you should see: After the rollback, Device Manager will show the previous driver version in Properties. That's your sign it worked.
Fix 3: Clean install your graphics driver with DDU (15+ minutes)
This is your nuclear option. If the first two fixes didn't work, something is stuck deep in the driver stack. You need to wipe it clean and start fresh.
Don't skip this step just because it sounds scary. It's safe if you follow exactly. You'll need an internet connection and about 15-20 minutes.
- Download DDU (Display Driver Uninstaller) from the official Guru3D site. Get the latest version — version 18.0.8.5 or newer.
- Also download the latest driver for your GPU from the manufacturer's site (NVIDIA, AMD, Intel). Save it to your Desktop.
- Important: Disconnect your internet temporarily. Unplug the ethernet cable or turn off Wi-Fi. This stops Windows from auto-installing a bad driver.
- Restart your PC into Safe Mode. You can do this: hold Shift while clicking Restart from the Start menu. Then go to Troubleshoot > Advanced options > Startup Settings > Restart. When your PC restarts, press 4 for Safe Mode.
- Once in Safe Mode, run DDU (the downloaded .exe file). If it asks, let it extract itself.
- In DDU, make sure the device type is set to GPU. Pick your brand (NVIDIA, AMD, or Intel). Then click Clean and restart (not Clean and do not restart).
- DDU will remove every trace of your graphics driver. Your screen might flicker. That's normal. It'll restart automatically.
- After reboot, Windows will try to find a driver. Stop it. If you see a notification asking to install a driver, click "No" or close it.
- Now run the driver installer you downloaded earlier (the .exe on your Desktop). Run it as administrator (right-click > Run as administrator).
- Choose Custom (Advanced) during installation. Check the box that says Perform a clean installation. This ensures no leftover settings.
- Let the installer finish. It may reboot once or twice. Reconnect your internet after it's done.
- Now test if the error is gone. Open the app that was crashing.
What you should see: DDU will display a log showing what it removed. The driver installer will show a progress bar. After all that, your screen resolution might change — that's normal, it'll adjust.
Still getting the error?
If you've done all three fixes and the error persists, it's not the driver. You might have a hardware issue with your GPU or the cable. Try a different HDMI or DisplayPort cable. If that doesn't help, test your PC with a different monitor. I've seen a cheap cable cause this error more than once.
One last thing: Check if the app itself is broken. Update the video app (like VLC or browser) to its latest version. Sometimes the bug is in the software, not Windows.
