How To FIX "Windows Cannot Connect to the Printer Due to Windows Update"

 

”Windows Cannot Connect to the Printer” Due to Windows Update

Windows 10 shows the error ”Windows Cannot Connect to the Printer” after installing security updates KB5005568, KB5005566, and KB5005565. 

This update helps to protect against Windows Print Spooler impersonation. These updates break the TPC authentication level for network printers and cause the error “Can’t Connect to Printer”. Uninstalling updates usually fix the problem. 

If you can’t uninstall the Windows update because it was installed more than two weeks ago, the only way to fix the error is to use Registry Editor.

• Press Win + R Key at the same time.
• Type regedit  in opened Run Box.
• Hit OK.

Now, the Registry editor page will open after running this command in the run box then expand the Following Path or copy and paste it into the path bar 

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Print

After navigating the above location. Create a new DWORD (32-bit) Value that name should be (RpcAuthnLevelPrivacyEnabled) and press enter key to save the change. 

You can see the below image.

• Now, double-click on the newly created RpcAuthnLevelPrivacyEnabled value.
• In the Edit menu, you have to only change the set Value data To 0. Zero is the default number of Value data But we should check it once.
• clicking Ok to save the changes.

After the Registry modification does not forget to restart printer spooler services. a system restart is not required after modification.
