When I open C drive by double click it'll pop up Open With windows and ask me to choose the program to open C drive.?

Do one of the following or both:

FIRST SETTING

 

You need to set permissions on those volumes. Also, you need higher level account (administrator level is the highest).

To check whether your account is administrator one, open the control panel (classic view) and open "User Accounts". In the lower left corner should be your account name and account type (should read "computer administrator")

To set permissions follow these steps:
Open control panel (classic view)/folder options. Scroll down advanced settings window and uncheck the "use simple file sharing".
Apply and rightclick on the volumes in question, select properties and click on "security" tab. There you'll see detailed sharing permissions/restrictions for all relevant accounts on that particular drive/file/folder. (Taking that you have administrative permissions) click on "Administrators ([computer name]\Administrators)" (first one from the top) and check allow on "full control" and click "apply".
If you see your account name on the list, either remove it or allow full control. If you are only user on that PC I suggest removing it from the list, for you are administrator and comply with "administrators" permissions.
After setting the permission, click on the "advanced" button. In the first tab select "Administrators ([computer name]\Administrators)" (same as before) and check the "Replace permissions entries on all child objects with entries shown here that apply to child objects" and apply.

 

SECOND SETTING

 

try this
-------
open my comp>goto tools>folder options
select "show hidden files"
uncheck "show system files"

goto each drive by rightclick>explore only. DONOT double click drives.

delete the file with the name "autorun.inf"

restart comp OR endtask n run explorer.exe thru taskmanager

this will solve the problem....
