Hi, I don't know whether this was mentioned earlier. Recently there was a fix from MS for MediaPlayer. I believe it was KB 817787. I myself have a bit older version of it; anyhow I installed the fix. A scan with PestPatrol showed me the following two reg-keys: HKEY_CURRENT_USER\software\microsoft\mediaplayer\player\settings|client id HKEY_USERS\.default\software\microsoft\mediaplayer\player\settings|client id Now I know that PestPatrol has sometimes a false positive, but I have the feeling that that is here not the case. It looks to me that that fix installed again those reg-keys. Can anyone confirm this?
