the one I have is v1.2.573.0, 68.0 KB (69,632 bytes) and probably came with the OEM Roxio Creator suite. I don't like fact that it is always running in background as a service, since I rarely ever need or use CD labeling
It is created by Sure Thing CD Labeling software.
Control checksum + more info to implant in Windows services administrator program

I think it's service related to some Sure Thing software.

stllssvr.exe is a stllssvr belonging to SureThing CD Labeler from MicroVision Development, Inc.
May leave you with a blank desktop and no login

It is listed in Msconfig as manufactured by MacroVision Development Inc who provides CD/DVD labelers. In my case I have Express Labeler from Roxio and it is undoubtedly connected to that. It came pre-installed on my HP Pavilion before any other connections were made so it is undoubtedly safe.

I had a problem with my computer not shutting down so I did a clean boot and determined that stllssvr.exe along with RoxMediaDB9 were causing my computer to not be able to shut down. I had to diable both for my computer to shutdown and now it works fine. I don't know what is up with the file but since it's not neccessary I have it disabled.
came with roxio, open services and disable it, also delete it in activex
Is located in "C:\Program Files (x86)\Common Files\SureThing Shared\stllssvr.exe" so no doubt is part of the SureThing app.
This is a service often required for Roxio Express labeler that ships with many computers, it is safe to disable as it's not a Microsoft essential service. You may need to enable for proper function of Roxio's labeling software.
just disable services you don't need or use frequently in msconfig, disable stuff you don't need and about stllssvr, it's harmless and comes with Roxio
While troubleshooting windows 7 stuck at welcome screen, I found this service to be harmless, disabling it did not help towards the fix.
It is adware
It cause problems with startup and shutdown procedures. I turned it of in msconfig and the problem stopped.
