Stopping Outlook Blocking Attachments

I know this is covered all over the web but I'm forever forgetting it so if Outlook has started blocking email attachments i.e. ASP files you can easily adjust this by adding a String Key called "Level1Remove" to the registry, navigate to: Current User --> Software --> Microsoft --> Office (x) --> Outlook --> Security (where (x) is the version of office you are running: 9 = Outlook 2000, 10 = Outlook 2002 11 = Outlook 2003

Then right click and choose "New" and "String Key", then add in a list of the attachments you would like to allow seperated by semi-colons i.e.:
.exe;.mdb;.url;.asp;.aspx;.zip
