You can probably tell I’ve recently spent some time tidying up the user’s notification area for a XenApp deployment 🙂 As well as getting rid of some removable devices and various other bits of unneeded junk icons, I also wanted to remove the icon that shows the Citrix Provisioning Services vDisk connection. Now, you could just turn the option off in your base profile (if you have one), but sometimes you may get involved in a project after the base profile is already in place. So, to get rid of the vDisk icon for your users, set the following Registry value through the method of your choice (AppSense EM, Group Policy Preference, login script, etc.)
HKCU\Software\Citrix\ProvisioningServices\StatusTray
Value – ShowIcon
Type – REG_DWORD
Data – 0
Bingo – another part of the UI you don’t have to worry about those poor end-users getting themselves into.
