with having problems with windows live messenger on win xp 64 I looked to the internet for support, I cant remember the error but looking into it seemed to be a registry permissions error... little more searching and I found this:
http://winonline.blogspot.com/2005/11/reset-entire-registry-permissions-to.html
following the instructions and nothing happening I thort I would run the new file I might have even made it a batch file instead of a cmd file. what would happen if the file (be it a CDM or BAT) was run with this text:
subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=administrators=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=administrators=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=administrators=f
subinacl /subdirectories %SystemDrive% /grant=administrators=f
subinacl /subkeyreg HKEY_LOCAL_MACHINE /grant=system=f
subinacl /subkeyreg HKEY_CURRENT_USER /grant=system=f
subinacl /subkeyreg HKEY_CLASSES_ROOT /grant=system=f
subinacl /subdirectories %SystemDrive% /grant=system=f
now the system wont start any further than just after the large windows flag, cant log in or anything, safe mode or normal.
PLEASE HELP, sorry for the essay.
thanks.
