delete installed hotfix files ??

[Guest]

is it good maintenance practice to delete (from software
and programs group in control panel) previously installed
hotfix updates still listed (may be 10 to 12 updates
listed) and keep only the most recent?

Absolutely not.
If you remove them, you also remove the fix.
However you can safely delete the uninstall files:
