I need to restore my desktop. It's an emachine ET series.
Now, what do you mean restore the desktop ? Just the desktop, the whole machine ? If having problems accessing desktop and you have restore points to fall back on, choose a date when the computer was working correctly and do a Windows System Restore.
or, take your pick from some of these:http://www.bing.com/search?q=emachine+et+restore&form=MOZSBR&pc=MOZI
