3 CIS in Windows startup

Occasionally uninstalling CIS, it still leaves the installer as a startup entry.

You can check here in Regedit and remove the redundant ones and restart your machine.

In registry there is only one
There is some in Task Scheduler

That is correct; same Task Scheduler entries are here as well. Can @C.O.M.O.D.O_RT comment on the individual functions and if all tasks are intended to run as per their current defaults?

Hi infosec,

Thank you for reporting.
We will check and report this to the team.
