I think it's the Solidworks Explorer plugin for Windows Explorer.
I believe it's the "Solidworks Fast Start".
From the Solidworks Help:
SolidWorks Fast Start
To launch more quickly, SolidWorks begins loading components in the background when you start your computer.
Solidworks Fast Start might slow down your Windows login time slightly.
To turn off SolidWorks Fast Start:
You can restore SolidWorks Fast Start by repairing your SolidWorks installation.
- From Windows, click Start > All Programs > Startup.
- Right-click SolidWorks Fast Start and click Delete.
- When the dialog box appears, click Yes.
You nailed it. It's been years since I had ever had a reason to look in the Startup folder, I had forgotten it was even there! I'm totally OK with SolidWorks taking a little while to load. If anyone was really that concerned with loads times they should just spring for a SSD.
Andys response seems reasonble to me, but is there any way to test this to see how it affects both SW and the rest of my computer experience? You repair your install, and no matter what you do (SWreg backup, etc) you lose some settings and you all know where that's a pain...
And no, my co-workers won't let me do it on their machines unless I do it on mine first...
It's just a shortcut. I'm not sure why they would suggest doing a repair to restore the Fast Start thing. Instead of deleting the shortcut, just move it out of Startup. You should be able to just move it back in there if you want to restore.
