Rufino:
If you mean that you want to see folders on the hard drive rather than My
Computer and so forth:
Choose the Windows Explorer icon, right click and choose Properties. The
target field will have the Explorer executable, usually:
%SystemRoot%\explorer.exe
Change the suffix of explorer to SCF. In essence:
%SystemRoot%\explorer.scf
Click OK
This will cause Explorer to open rooted in the boot drive.
Good luck,
S
