I've got this machine for over an year now, and last friday, I shut it down normally, but on the other day I rebooted it, and it took a long time to load, as well as it changed to "Classic theme", having a message that Windows couldn't connect to one of it's services. I've done and attempted many fixes and I still don't understand why it doesn't work. I've tried these various solutions:
The services.msc, the changing back and forth(works, but when I reboot it, it returns to point zero), safe mode with a code line I found in a forum saying it would fix it, the regular "greyed out" solution.
These solutions included registy changes, stopping/starting services, and force starting the aero theme.
As none of those worked, I'm asking here for help, as this is very unpleasant to deal with everytime I turn the computer on.
EDIT: I've tried the Microsoft FIX IT tool as well, it identified the problem, but was not able to fix it, it suggested for me to use the troubleshooter of my computer, but it only froze and stayed like that.
