Are you screwed by the problem that when you Double click on some drive it opens in a new window? Then do not worry you can fix this problem manually in seconds.
First of all check if by mistake you haven’t ticked the option under General tab in Folder Options. If not it means that the problem is due to some virus activity.
Steps to fix the problem:
Solution 1
• Open start menu and click Run.
• Type regsvr32 /i shell32.dll
• Click Ok and if this message shows “DllRegisterServer and DllInstall in shell32.dll succeeded” that means the problem is solved.
Another method:
Solution 2
• In Run type regedit.exe to open the registry editor.
• Traverse to HKEY_CLASSES_ROOT/Directory/Shell

• Double click on the default value on right and set it as “none”.
• Repeat the procedure for the key HKEY_CLASSES_ROOT/Drive/Shell.
