I had a problem with open folders and right-click in Windows 10, and solved it today.
First look at the System Logs in Event Viewer:
Unable to start a DCOM Server: {9F156763-7844-4DC4-B2B1-901F640F5155} as Unavailable/Unavailable. The error:
"2147943631"
Happened while starting this command:
"C:\WINDOWS\system32\DllHost.exe" /Processid:{9F156763-7844-4DC4-B2B1-901F640F5155}
if you have a similar log, you can disable it from the registry with steps below,
Open the Registry Editor app.
Go to the following Registry key. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Blocked.
On the right, modify or create a new string (REG_SZ) value {9F156763-7844-4DC4-B2B1-901F640F5155}.
4. Leave its value data empty.
5. To make the changes take effect, sign out and sign in to your user account. Alternatively, you can restart the Explorer shell or restart Windows.
