Re: Are printer-related registry keys are safe to remove?

2011-03-31 Thread James Rankin 
Indeed this appears to be the case. I created an AppSense logoff action to
delete the keys, and then create them again blank. This has stopped the
drastic over-population of these with printer entries, and has increased the
logon time for this subset of users.

Thanks!

RE: Are printer-related registry keys are safe to remove?

2011-03-30 Thread Ken Cornetet 
Yes, they are safe to remove.

I created a batch file with these two lines and call it from a group policy 
logoff script.

reg DELETE "HKCU\Software\Microsoft\Windows NT\CurrentVersion\Devices" /va /f
reg DELETE "HKCU\Software\Microsoft\Windows NT\CurrentVersion\printerports" /va 
/f

I will have to say, though, that this seems to make some user's Citrix session 
hang (they never logoff after closing their last app). I will probably move 
this to a logon script at some point.

Subject: Are printer-related registry keys are safe to remove?

There are two Registry keys - HKCU\Software\Microsoft\Windows 
NT\CurrentVersion\Devices\ and HKCU\Software\Microsoft\Windows 
NT\CurrentVersion\PrinterPorts - that, in a terminal services environment, seem 
to fill up with vast amounts of printers, apparently enumerated from any user 
that has ever logged on. Now some older pieces of software seem to look here 
for their printer settings, to the extent that when there are approximately 500 
entries in there, meaning that the printing from these apps is very, very slow. 
According to an MS article these keys are for user preferences for print 
devices in Windows NT 4.0, so, would I be right in assuming I could simply 
remove all entries from these keys at logoff without causing myself any 
problems?

TIA,



JR

Re: Are printer-related registry keys are safe to remove?

2011-03-30 Thread James Rankin 
Both those keys just appear to fill up with every printer that has ever
mapped on the Terminal Server, every time it populates. It is full of
printers "*from session x*" corresponding to other users on the Terminal
Server. The user can't see them in Devices and Printers, but they are all
dropped into these keys.

The sooner I bin these damned roaming profiles the better

  Shouldn't anything under HKCU (HKEY_CURRENT_USER) be a per-user
setting, and not from any user who has ever logged on to your Terminal
Server?  Or is everyone logging on under one user account?
