Well, Windows has its own problems with installers and permissions, 
but they are a different kind of issue than would need to be 
"repaired" by an OS utility. 

The problem is quite similar in that much of it is caused by 3rd-
party applications that aren't appropriately designed to run properly 
with LUA permissions (i.e., the most limited permissions of a user 
rather than an administrative level of access), the installers in 
almost all cases (because of the insistence on protectin the default 
programs folder), and many applications at run-time (QuickBooks is 
one of the worst offenders, requiring at minimum the Power User 
permissions to be run at all).

I don't quite understand the fear of changing permissions. In my 
experience with OS's with file systems that allow the control of file 
access, it's something that *ought* to be something the user has full 
control over. Being able to set permissions is a *feature*, a 
benefit, not something to be feared!
