Some items are starting up on a Windows 7 desktop PC that I don't want, namely Skype, Teamviewer, Quicktime, Dropbox, and a few more.
I use msconfig to untick them from the Startup tab. I click Apply, OK, reboot, and then the items startup again, and they are ticked in msconfig Startup tab.
I am logged in as the only administrator of the PC.
Why is this happening?
