Improving XenDesktop/XenApp 7.x logon times for Windows Server 2012/2012R2

Hello Folks,

with a small trick you can strongly improve the login times for Windows Server 2012/2012 R2 in a XenApp/XenDesktop 7.x environment or if you run into a black screen during the login.

Just delete the registry entry HKCU\Software\Microsoft\Windows\CurrentVersion\UFH\SHC for example thru an login script, see also KB 3161390. We reduced the login time for a User from more than 40 seconds to less then 20 seconds without any negative impact, so it’s worth to try it out.
