[Help] Theme

hello people, i'm new to this forum :)
please have the time to read and help me
thanks for all the help

i booted my laptop but i pressed the power button twice
so it shut down again
when i boot it up
thinking that i had crashed or had a problem
it showed the warning "Windows was unable to start at the last time blah blah blah"
then there's two option (you all know this)
one to scan for problems (recommended)
the other to start windows normally
well i picked the Recommended one, cause i don't know, i haven't done it
so i canceled it to restore to its factory state, so then it scans once more for problems
i, knowing there isn't any problem, wanted to cancel it but it said i can't
it was taking too long. i held the power button to force shut down
then i restarted it, now it didn't show up
so after i log in, my theme is like the old window classic theme
i tried personalizing and picking different style, but it goes to the same classic theme
also my start orb is back to default even if i change my explorer.exe file
i have downloaded new themes, but it only goes to default

wth is wrong with my computer?
only the default aero and the other pre-sets theme works

so i did the restore
but the theme still goes to classic

i did that already and haven't change anything

but i just re-run the system restore but at a later time.
and it's back to normal. i just need to re-install the delete programs due to the restore
thanks for the help

ok, i'll asure this time
thanks
