expired root certificates

[Clint Wilson]

Noticed in my certificate store that there are some
certificates issued by Microsoft that have expired in
1999, or 2002. Question: Since these are 'system'
certificates should they be 'updated' or should the
expired certificates be deleted? When trying to delete
them I get a warning that deleting the system certs may
cause some windows components to not run properly.

Delete or not delete?
Thanks
Clint

They are benign. You can just leave them there.
