Object Desktop unfortunately every now and then at the start of Winsows stops me to restart the computer

Try uninstalling Windowblinds, run CCleaner and reboot. Re-install Windowblinds and instead of rebooting from there close out of it then do a reboot, if you can. Might help unless someone comes along with a better idea.

Object Desktop is a suite of programs, containing apps for several OSes. In and of itself, it doesn't "start or stop"

What program in particular is asking for a reboot and what settings are lost. Screenshots of the prompts and the settings window will help.
