Number one; I never really thought that Tweaking Repairs or Performance Tweaks caused my problem. I asked because everything started about the same time.
Number two: I had tried the answers.microsoft procedures and others; none of which worked.
Number three: I wish I could remember where I found this but it worked for me;
Open Internet Explorer, Internet Options, Advanced, click "Reset" (Internet Explorer) Restart Computer
Open Internet Explorer, Internet Options, Content, Feed Settings, Remove check marks for all advanced options.
Open Windows Live Mail, click Views, click the Quick Views icon and remove check mark for "Unread Feeds"
I currently do not use RSS feeds. I clicked Feeds in the Quick View pane and deleted all feeds listed.
The RSS initialization error was gone and then I received a group of Windows Updates. Because of the updates, I ran Tweak Repairs again. The RSS initialization error message returned. I ran the above procedures and it is gone again.
