IMPORTANT: This article contains information about editing the registry. Before you edit the registry, make sure you understand how to restore it if a problem occurs. For information about how to do this, view the "Restoring the Registry" Help topic in Regedit.exe or the "Restoring a Registry Key" Help topic in Regedt32.exe.

SUMMARY

If you are troubleshooting Windows NT or applications that are running in Windows NT, you may need to verify that a print share or installed printer has been completely deleted. The following information shows the default locations in the registry database for references to installed printers or print shares in Windows NT versions 3.1, 3.5, 3.51 and 4.0.

MORE INFORMATION

It is rarely necessary to remove a printer by altering the registry. In most cases, you can remove a printer in Print Manager or the Printer folder using the Remove or Delete Printer option. This immediately removes the printer, but internally the spooler marks the printer for deletion and does not actually delete the printer until the next time that the Spooler Service starts. Therefore, you should stop and restart the Spooler Service before attempting to recreate a printer, or before attempting to remove a printer port that a recently-deleted printer was using. Also, you should close Print Manager or the Printers folder before restarting the Spooler.

In summary, if you use the Print Manager or Printers folder to remove a printer or printer port, then close Print Manager or the Printers folder, stop and restart the Spooler Service. If you reopen Print Manager or the Printers folder, and the printer or port is still present, then you should consider removing the printer or port by altering the registry.

NOTE: ALL references must be deleted to ensure complete removal of the print share or installed printer. You must also either Stop and Start the Spooler Service or shutdown and restart Windows NT for these changes to take effect.

Modifying the Registry

WARNING: Using Registry Editor incorrectly can cause serous problems that may require you to reinstall your operating system. Microsoft cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk.

For information about how to edit the registry, view the "Changing Keys And Values" Help topic in Registry Editor (Regedit.exe) or the "Add and Delete Information in the Registry" and "Edit Registry Data" Help topics in Regedt32.exe. Note that you should back up the registry before you edit it.

NOTE: Registry keys in the following procedure may appear on two or more lines, but are actually one path; they have been wrapped for readability.

1. Run Registry Editor (regedt32.exe).

2. Go to the appropriate registry location mentioned below for your version of Windows NT.

3. Delete the registry information for printer(s) and/or server(s) you want to remove.

   NOTE: It is recommended that you first save each registry key before deleting it.
