I tried to execute Skype but I had to reboot my comp since it crashed, as Windows started I noticed that its look had changed!!!
The application bar with the "start" button don't appear in "Windows XP" style but in the old "Windows" one.
Then, when I click the start button, also the menu that appears looks like the old Windows 98, it's all grey and the picture that usually comes with my profile's name desappeared and only my name is still there.
Then, the upper bar of every window (the one with the cross on the right) is smaller.
What is that?!
PLEASE SOLVE MY PROBLEM!!!!!!!! I'm into panic now!
