Strange one this! One day fine, shut down system, started up system the next day and Solidworks, was really slow to start up. It works ok, but I wanted to find out why Solidworks was slow to start up. So I stopped each service in turn and found that if I stop the print spooler, (spoolsv.exe), Solidworks starts quickly again. Starting the print spooler service, results in Solidworks starting up slowly again. I have repeated this many times, to prove it, has anyone any ideas why, this service should affect Solidworks start-up? There are no physical printers attached to my pc, the printers that I use, are attached to another workstation. Both are using XP Pro Sp2. Could it be the security settings on the PC used as the print server? Both of the printers are shared and I can print from both printers. HP450c and HP1220c. Thanks.
