Agreed, however, in some of my dabbling with python (again just me trying to get my feet wet) as well as in batch files, isn't that like fundamentals 101, #commenting things like this so you can see what its doing Either way, its an unexpected "summer bonus" for me :)

As the project progressed with things being added and changed the memory of using that shortcut got lost. Since it always worked it never landed on the radar.

After installing ALL the printers on the box, print previews take about 1 second to load, and no MSIexec. This will be one costly lesson to the client :) as I spent quite sometime on this.

What happens is that whenever a remote user (either citrix or RDP) prints (or logs on, I forget), the local printers FOR ALL LOGGED IN USERS get GUIDs assigned that are unique for that user’s session. The stupid HP print drivers (maybe other too) create keys under HKU\.Default\Software\Hewlett-Packard corresponding to ALL THESE GUIDS. This rapidly results in thousands of keys. For some reason, msiexec.exe likes to fully traverse that key OVER and OVER and OVER resulting in msiexec using 100% of one CPU AND msiexec taking forever to get anything done.

Can I just disable the server from even attempting to enumerate, the option of upgrading to a new OS is not really viable at the moment.
