Once again I have setup here an 64bit Win7 pro system.
Many of the files from the D: partition were taken from the previous Win7 system resp. copied from another Win7 (WinXP) computer.
When I look at some of the security tabs of some of the files and folders then various user entries exist...
64-bit
access control
active users
admin rights
cleanup
file management
file security
maintenance
migration
old files
orphanusers
permissions
recycle bin
