Today my new PC had something wrong with IE.
It made me so disappointment. However I used Ghost, software, to revert to original state.
I didn't want to complain about the trouble I met.
Altough I had made it reverted twice this winter vacation, it took me half one hour to install series of the useful softwares.
I think I can engage in a computer engineer~after make the computers reverted hundreds of times.
~Aha~
