Fix 0xC01E0518: HDCP Hardware Already In Use

What Causes Error 0xC01E0518?

You'll see this error code 0xC01E0518 (STATUS_GRAPHICS_OPM_ALL_HDCP_HARDWARE_ALREADY_IN_USE) when your graphics card has handed out all its HDCP (High-bandwidth Digital Content Protection) licenses to other programs. HDCP is the copy protection used by Netflix, Blu-ray players, and streaming services. Your GPU can only issue a limited number of HDCP sessions at once—usually 1 or 2 on consumer cards like an NVIDIA GeForce RTX 3060 or AMD Radeon RX 6600. If you're running multiple apps that demand HDCP, like having a Chrome tab playing Netflix while also running a Blu-ray software player, the second app gets this error because no HDCP slots are free.

The error pops up most often when you try to play protected content through a secondary monitor, a capture card, or after closing a game that used full-screen exclusive mode. I've seen it happen on Windows 10 22H2 and Windows 11 23H2 systems with multiple displays connected.

Fix 1: Close Conflicting Apps That Hold HDCP Licenses

This is the most likely cause and the easiest fix. Something already grabbed the HDCP slot and won't let go. Here's what to do.

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Click the Processes tab.
3. Look for these common offenders: Google Chrome, Microsoft Edge, Netflix (UWP app), VLC, PowerDVD, any Blu-ray software.
4. Right-click each one and select End task. Don't worry—you're just closing the app, not uninstalling it.
5. What to expect: After closing all of them, the error should be gone when you retry your streaming app. If it's not, move to the next step.

Sometimes a background process like nvcontainer.exe (NVIDIA Container) or amdfendr.exe (AMD Framework) can hold the HDCP session even after you close the main app. If you see those in Task Manager, end them too. They'll restart automatically next time you reboot.

Fix 2: Restart the Graphics Driver (Without Rebooting)

If closing apps didn't work, the HDCP license might be stuck in a zombie state on the driver side. Restarting the graphics driver releases everything, including HDCP sessions.

1. Press Win + Ctrl + Shift + B all at once. Your screen will flash black for 1-2 seconds. That's normal—it's the driver restarting.
2. What to expect: You'll hear a beep (Windows 10/11) and your screen will come back. Try opening your streaming app again.

I've used this trick hundreds of times. It clears HDCP locks without needing a full reboot. If the black flash doesn't happen, you pressed the keys wrong—try again with all four fingers.

Fix 3: Disable and Re-Enable Your Graphics Card in Device Manager

When a driver restart isn't enough, a full device reset usually works. This forces the GPU to reinitialize its HDCP module from scratch.

1. Right-click the Start button and select Device Manager.
2. Expand Display adapters. You'll see your graphics card listed (e.g., NVIDIA GeForce RTX 4070 or AMD Radeon RX 7900 XT).
3. Right-click your graphics card and select Disable device. A warning will pop up saying it might make your display go dark. Click Yes.
4. Your screen will likely go black or low resolution for a moment. Wait 10 seconds.
5. Right-click the same entry again and select Enable device. Your screen will flash back to normal.
6. What to expect: After the card re-enables, the HDCP hardware is free. Test your streaming app now.

This is a nuclear option compared to the keyboard shortcut, but it almost always works. I recommend this over rebooting because it's faster and doesn't disturb other running programs.

Fix 4: Check for Multiple Displays or Capture Cards

Some setups like dual-monitor configurations or external capture cards (Elgato HD60, AverMedia) can each demand separate HDCP licenses. Most GPUs only support 1-2 HDCP sessions total. If you have two monitors playing protected content simultaneously, or a capture card trying to record HDCP-encrypted video, you'll hit this error.

1. Disconnect all extra monitors except your primary display. Unplug any capture card devices.
2. Restart your computer or use the driver restart trick from Fix 2.
3. Try playing the protected content again on just one screen.

If this fixes it, you've got a hardware limitation. You'll need to choose which display or capture card gets the HDCP session at any given time. There's no way around it on consumer GPUs.

Fix 5: Update or Roll Back Your Graphics Driver

Outdated drivers can have bugs with HDCP session management. But also, brand-new drivers sometimes introduce regressions. I've seen both.

1. Press Win + X and select Device Manager.
2. Expand Display adapters, right-click your GPU, and choose Update driver.
3. Select Search automatically for drivers. Windows will check and install any newer version.
4. What to expect: After installation, restart your PC. The error should be gone.

If you're already on the latest driver and the error started after an update, roll back: go to the GPU's Properties > Driver tab > Roll Back Driver. This reverts to the previous version.

Real-world example: I saw this error on a Dell XPS 15 (2022 model) with an NVIDIA RTX 3050 Ti. The user had Chrome playing YouTube TV (which uses HDCP) and then opened the Netflix app. That's two HDCP users on one GPU. Closing Chrome fixed it instantly.
