Fix for [Failed to start filtering: failed to open device (code:3,31,1058, 1072, 1073). make sure you run clumsy as administrator]

Hey guys!

Here are the exact steps I followed to resolve this.

---

1. Open Command Prompt as Administrator** and delete the service (skip if it doesn't exist):
   sc delete WinDivert

2. Open Registry Editor (Win+R → regedit → Enter), navigate to:
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WinDivert
   If it exists, delete the whole WinDivert key!

3. Restart your computer – this is mandatory.

4. Download GoodbyeDPI, extract it, copy WinDivert64.sys from the x86_64 folder to your Clumsy directory, overwriting the old file.
   (I don't know if this step is necessary, but I did replace the file anyway.)

5. Restart again, and during boot hold down the Shift key to enter the recovery menu:
   Troubleshoot → Advanced options → Startup Settings → Restart
   Then press 7 or F7 to select "Disable driver signature enforcement".

6. After the system boots, open Command Prompt as Administrator again and run these two commands:
   sc.exe create WinDivert binPath= "your\Clumsy\path\WinDivert64.sys" type= kernel start= auto
   sc start WinDivert
   Example:
   sc.exe create WinDivert binPath= "D:\clumsy\WinDivert64.sys" type= kernel start= auto
   sc start WinDivert

7. If you see output like this, the driver has started successfully:
   SERVICE_NAME: WinDivert
   TYPE : 1 KERNEL_DRIVER
   STATE : 4 RUNNING
   (STOPPABLE, NOT_PAUSABLE, IGNORES_SHUTDOWN)
   WIN32_EXIT_CODE : 0 (0x0)
   SERVICE_EXIT_CODE : 0 (0x0)
   CHECKPOINT : 0x0
   WAIT_HINT : 0x0
   PID : 0
   FLAGS :

Now u can open Clumsy as administrator, or restart your computer and then open it as administrator.
Hope this helps! :)
