Came across this issue recently in our xenapp 6.5 environment when users’ complained of poor performance post logon. Noticed that spoolsv was consuming large amounts of CPU for the 1st minute or so of logon and then things would be ok.
Other thing I noticed was a huge number of mapped printers within HDX Monitor and when printing in office the drop down list would show hundreds of them.
Turns out the vast majority of the printers are XPS document printers – an office 2013 by-product.
Quick google and I found
