Though frequently there are "side effects" that you'll have to deal with. One of which is the forced regeneration of user profiles and subsequent relocation of the user folders. You can't simply re-set the user folder to the original one as it often contains munged registry info, and binary info in the Application Data folder is likely no longer valid. At best you'll have to simply copy/move user documents over to new user folders.
If the affected program files (EXE, DLL, etc) aren't part of the OS but are part of the application -- the repair install of Windows won't solve your problem. Windows will likely operate fine afterwards (though perhaps with a few "quirks"), but affected applications will likely not. At that point you have to re-instal the applications.

Another way to quickly "repair" a system is with harddisk images -- that way you can revert to an earlier image if something happens. This of course requires that you take act preemptively and occasionally create the partition images (on separate media of course). It tends to work best if you keep your OS and programs separate from user documents (i.e. you leave your boot partition to be used only for OS and program files -- the documents you keep in a separate data partition. That way when you 'roll back" using an earlier image, only the program information is rolled-back and your documents remain unaffected).
