I have windows xp with adminstrative right. Yesterday i go to “my computer” icon on my desktop and saw that “my computer” view icon has changed. Before that it was shown in three catagories such as
“Files stored on this computer”
“Hard Disk Drive”
“Devices with removable storage”
Now all the hard drive icon and other icon on “mycomputer” is changed and alligned in a row. I have checked that the view of “my computer” is still set on icon but view has changed. Now i wanted to restore the original view icon of “my computer”. Please help me how to do it.
