sridhar.k24, Download the free tool called Remove Restrictions Tool (RRT) at the link below.
Make sure you boot in to Safe Mode to use Remove Restrictions Tool (RRT).
When i goto the FOLDER OPTIONS and goto the VIEW tab, in the hidden files and folders i find only "Do not show hidden files and folders" and no option for showing hidden folders! I'm not able to open hidden folders because of this.
Can anybody tell me whats the problem. I'm using Windows Vista Home Premium.
