Windows 7: sysprep copyprofile copies all the junk files too

when i use unattend.xml answer file, and add the copyprofile string, sysprep copies a bunch of stuff to the default profile folder.

stuff like usrclass.dat, etc.

original untouched Default directory is under 3MB.

after sysprep copies my customizations, it's 10MB, with a lot of files.

As my customization, all i did was go to folder options and unhide all files, and pin a couple apps to the start menu.




is it normal for sysprep copyprofile to copy over so many files? Are these files unique to the Administrator account?
Is it ok for these files to be placed in the Default directory, to be copied to every subsequent user account that is created?
