One of the new features in Internet Explorer 8 is InPrivate Browsing, which helps prevent Internet Explorer from recording any kind of data about your browsing session or habits.
Basically, when in an InPrivate Browsing session, no cookies are created, no temporary Internet files, no history, no form data, and anything else that a browser would normally record.
Note: The InPrivate Browsing feature of IE 8 is different than InPrivate Filtering. InPrivate Filtering prevents other sites from tracking your browsing habits, instead of the browser not tracking your session (InPrivate Browsing).
If you’re an IT manager, this new feature may hinder your tracking of Internet usage for employees, students, etc. There may be times when you need to simply disable InPrivate Browsing for all users on a PC.
You can do this by going into Group Policy and changing the setting there:
Step 1: Go to Start, then Run and type in gpedit.msc.
Step 2: Now navigate to the following section:
Computer Configuration / Administrative Templates / Windows Components / Internet Explorer / InPrivate
Step 3: Now on the right-hand side, go ahead and double-click Turn off InPrivate Browsing and choose Enabled.
You can turn it off for only the currently logged on user by simply going under User Configuration first.
If you keep looking, you will also see the options for turning off InPrivate Filtering, not collecting InPrivate Filtering data, and setting the InPrivate Filtering Threshold. Enjoy!
