I tried to install the just released update of windows 8.1, but after several reboot it said it couldn't install it with the error :

windows 8.1 couldn't be installed with error 0xc1900101 0x20006

I don't have truecrypt or bitlocker, just a dual boot with MacOSx86 (hackintosh) and chimera bootloader, I am not sure if it has anything to do with the error.

Here is the interesting part of WindowsUpdate.log : http://pastebin.com/hxchfKii And here is the full download and installation log : http://pastebin.com/A4NBLfuU
