Win7 -- Will Global Policies survive domain disjoin?

A Win7 Pro workstation was joined to a domain and the admins installed some Global Policies that block local administration.
It can no longer connect to the PDC and we want to disjoin the workstation from the domain.
Will the Global Policies from the PDC survive or not?
There are policies that prevent Windows Updates, etc, etc, and we need this workstation to revert to a local-only status.
Will those policies be removed if the PC is disjoined from the nominal domain?
Thanks...
