If you allow users to accumulate personal music and images in their documents folder, then roaming profiles don’t work well.
I simply tell people they have to keep personal stuff out of My Documents. No one accumulates gigabytes of Word Documents. Not in my experience.
It isn’t Word documents- I’m dealing with programmers/developers. Of all of the data I have to move around, MS Office files are the least of it.
We used to be allowed by policy to ignore their personal data when reimaging a unit. That unfortunately, has changed.
