How to Fix the Spoolsv.exe Application Error

1. Click on the Start button and click on Control Panel. Click on Performance and Maintenance and then select Administrative tools.
2. Click on the Services option. Locate the Spooler services in the Services Management Console. Right click on it and then click on Stop.
3. Double click the C:\windows\System32\Spool\Printers folder to open it. (This step assumes that you have Windows installed in the C: Drive). Delete all of the SPL and .SHD files that are in this folder.
4. Open the TMP folder, and then delete all of the old, unused files you find in it. Restart your Spooler service from your Services Management console.
5. NOTE: You may be unable to delete these files while in Normal Mode. In this case, you will first need to reboot your PC in Safe Mode. To do this, tap the F8 key at system restart, then choose the Safe Mode option from the Windows Advanced Options Menu. Press Enter.
If this still does not work, you may need to perform a System Restore.
