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. Ken Cornetet 812.482.8499 To err is human - to moo, bovine. From: James Rankin [mailto:kz2...@googlemail.com] Sent: Wednesday, March 30, 2011 4:01 AM To: NT System Admin Issues 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 -- "On two occasions...I have been asked, 'Pray, Mr Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question."
