roaming-profile

I'm using a (non-administrator) roaming profile, with a size limit of 4MB.

As you can imagine, it is extremely difficult to stay within that size limit.

I've noticed that NTUser.dat, which holds my HKEY_CURRENT_USER hive, is 2560KB, single-handedly using more than half of that limit.

Is there any way to shrink the hive without administrator privileges?
I don't mind losing any settings or preferences stored in it.
