How to Disable SMB1

WannaCry and Co. suggest that it’s time to remove some old protocol, and SMB1 it’s one of that.

Here you find a script that is usefull for that; run it as admin rights:

How to Delete WSD printer Port

I had a Windows 2012 R2 printserver where a WSD port was still there after printer deletion. Delete only the port was not possible (operation not permit).

The spooler will delete the port only if it is assigned to a printer and you are deleting the printer. As workaround you can create a fake printer using this port and a preinstalled driver, then delete the printer.

But using powershell is possible to work less…

List all the WSD Printer Port:

Get-PrinterPort -Name wsd*

Delete the WSD Printer Port (PortName):

Remove-PrinterPort -Name PortName

or if you have only one WSD port:

Remove-PrinterPort -Name (Get-PrinterPort -Name wsd*).name
