Windows 7: C?\ Instead of C:\ in Registry

19 Oct 2016   #1

Windows 7 Ultimate
C?\ Instead of C:\ in Registry

Only in the following key:


I see many instances of file references like this:

"C?\\Program Files\\ATI Technologies\\ATI.ACE\\Fuel\\amd64\\aoddriver2.sys", or
"22:\\Software\\Adblock Plus for IE\\1.5\\InstallFolder", or
"21:\\Software\\Hewlett-Packard\\ESB\\HPTouchSmart\\SmartCenter\\", or
"02:\\SOFTWARE\\Microsoft\\Updates\\Microsoft .NET Framework 4.6.1\\KB3127233\\ThisVersionInstalled"

As far as I know this has never presented a problem but what are these strange drive references? Thanks.
