I was already referred to this Microsoft support page in a previous thread: http://support.microsoft.com/default.aspx?scid=kb;en-us;330135&FR=1&PA=1&SD=HSCH But I seem to have hit a snag. When opening regedit and checking my HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer\NoDriveTypeAutoRun file, as step 7 suggests, the file is available only in binary, not hexadecimal. (It's labeled as REG_BINARY.) So, I can't edit in a hexadecimal value of 91, as the Microsoft page suggests. The display, when I right-click to modify it, is 0000 FF 00 00 00 y... I'm not sure where to go from here. Can I somehow this existing NoDriveTypeAutoRun file, or copy a "good" one with a hex value of 91 from my Windows install CD? Any help would be greatly appreciated. I'm pretty sure this screwed-up reg file is the problem.
