Batch Delete Issued Citrix User/Device Licenses with Udadmin

Udamin.exe is a handy tool for managing Citrix user/device licenses.

To get a list of currently issued licenses run it like this:

C:\Program Files\Citrix\Licensing\LS>udadmin.exe -list

computername2 XDT_PLT_UD 2013.0815

You can delete individual license assignments like this:

udadmin -f FEATURE [-device | -user] NAME -delete

Unfortunately there is no built-in command that deletes all issued licenses. A one-liner batch script adds that missing functionality for device…

for /f "tokens=1,2" %i in ('udadmin -list ^| find /i "_ud"') do @udadmin -f %j -device %i -delete

…and user licenses:

for /f "tokens=1,2" %i in ('udadmin -list ^| find /i "_ud"') do @udadmin -f %j -user %i -delete

If you have both types of licenses, just run both commands one after the other.
