Inprivate filtering in IE disables itself

Question

I recentl discovered the built-in ad blocker in IE8, called inprivate filtering. It however disables itself on every IE start. How to enable it permanently?

Answer 1

This TechNet article explains how.

However, you can tweak the registry to keep the InPrivate Filtering feature on at all times by default. Open Registry Editor, navigate to HKCU\Software\Microsoft\Internet Explorer\Safety\PrivacIE, add the DWORD value StartMode (if it doesn’t already exist), and set its value to 1. Internet Explorer will now retain and apply whatever decisions you made in the InPrivate Filtering Settings dialog box.
