MSFeedSync.exe is an executable file used by the Windows Internet Explorer 7 web browser to periodically update in-browser RSS feeds. It only appears in the Windows Task Manager if IE7 is running. In addition it only appears from time to time and isn’t in "always on" state.

If you use the IE7 feature to read feeds in-browser, you need this enabled in order for it to work. However if you use another feed reader (such as Google Reader, Bloglines, RSS Bandit, FeedDemon, Thunderbird, etc.) you can safely disable this.

To disable:

1. Go to Control Panel.

2. Double-click Internet Options.

3. Click Content tab.

4. Click the Settings button under Feeds. See image below for example.

5. Uncheck Automatically check feeds for updates. See below for example.

That’s it. Click OK a few times to exit.
