Recently, I did a spyware scan on my laptop, but found few annoying ActiveX Controls running under IE7. So I change the security setting in IE7 to stop most of the ActiveX Controls. However, I restart the IE7 browser and getting the annoying "Customize Your Settings" home page every time. Even I change the default home page to "about:blank", it still starts with the "RoundOnce" page from http://rononce.man.com/runonce2.aspx.
I have no idea what this page does, but I believe that Microsoft is trying to guide the IE7 user to setup their IE7 and download new add-on from an non-Microsoft web sites. That looks weird!
After digging into the registry for IE7 and found a place to turn off the Runonce.msn.com start-up page. Basically, it requires two registry key to do the magic.
Open Regedit and go to the following section.
Look for the following two keys.
if they do not exist. Add them by right click mouse -> New -> DWORD Value as shown in the image below.
Modify the value and set the value to 1 for both DWORD values as the images below.
Restart your IE7 browser. The annoying Runonce page is gone!
