V411 - 413, Large Number of ActiveX/Com/DCom/Ole/DDE Entries

Am running Vista Business. Starting with Build 411 and now on 413, the registry cleaner finds a large number of ActiveX/Com/DCom/Ole/DDE entries that it wants to remove. The scan says there are 1900 of these items; however, on removal there are only 424 items removed. They are all like the items below. Do these items really look like valid keys for removal? I let it remove them and the system has been running okay for 2 days, but....
