I've found this to be invaluable:
save to a .reg file, in plain text format:

[HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon]
"ExcludeProfileDirs"="Cookies;History;Temporary Internet Files;Temp;Recent"

Everything in the %windir% and subdirs is ignored during logoff.
Everything else is synced normally.
