Microsoft's Patch Tuesday is the gift that keeps on giving all month long.
If you're one of those 50 or so Windows RT users (I kid, I kid) who were affected by Microsoft latest round of botched Patch Tuesday updates, you should know that Microsoft has now pushed out a fixed update. In this case, though, the fixed update also comes with a brand new KB article number.
I guess Microsoft was so embarrassed, or maybe infuriated, at the complete lack of QC on this one, they just decided to scrap it all and start fresh.
Anyway, the fixed update has been reported to work and you should install it if your version of PowerPoint running on Windows RT is still not working.
