Unable to display feeds in Internet Explorer 7/8

Problem Description:
After clicking on a subscribed feed in Internet Explorer you get a message that the feed could not be downloaded.
If you run Internet Explorer as an administrator (right-click "Run as Admin") feeds are displayed as expected.
Solution:
Equipped with administrative privileges change the integrity level of your feeds folder (located under %LOCALAPPDATA%\Microsoft\Feeds) to low by typing:

icacls feeds /setintegritylevel (OI)(CI)low
