Recommendation

Follow the steps to resolve the issue, but discuss it with your IT department first if needed. Be cautious when editing the registry, as incorrect changes can cause system issues.

Procedure

The message indicates that the working directory is a UNC (Universal Naming Convention) path, but the Windows command shell is not configured to support UNC paths.

To resolve this, you need to enable command shell support for UNC paths by modifying the Windows registry. Specifically, you should set the DisableUNCCheck registry key. Here’s how you can do it:

1. Open the Registry Editor:

Press Win + R, type regedit, and press Enter.

.

2. Navigate to the Key:

Go to HKEY_CURRENT_USER\Software\Microsoft\Command Processor.

.

3. Create or Modify the DisableUNCCheck Key:

If it doesn't exist, right-click in the right pane, select New > DWORD (32-bit) Value, and name it DisableUNCCheck. Set its value to 1 to enable UNC path support.

.

4. Close the Registry Editor and restart your computer for the changes to take effect.

Final comments

Some users have asked about Step 3.

"I cannot find the following file location: HKEY_CURRENT_USER\Software\Microsoft\Command Processor."

As mentioned before, you have to create that folder in case it does not exist. This can be easily done, so do not worry.
