exe files locked-how to unlock?

There is the notion of why, but the CIS 3.8 blocked exe files, I used version 3.8 and CIS learned that causes such problems as above, so I installed and uninstalled CIS stable version 3.5, clean registry etc and the problem still occurs after nawed … click on the properties and select the option unlock, I logged on to the administrator account in Win XP, plus the options Defense + "Predefined Security Policies’'chose a trusted and exe files, and only some files to play the rest is locked, off the option execution Image Control settings and this problem does not occur in Safe Mode.
