Error: 0x800F0922 when installing KB 2919355

I've been getting error 800F0922 when trying to install KB2934018 (part of 2919355) ever since I did an in-place upgrade using the MSDN ISO just to get the regular 291935 update installed.

Now, I'm getting this same error message (800F0922) when trying to install KB2955164 (released yesterday) and also when trying to upgrade to Windows 8.1 Pro using a license key and the anytime upgrade program.

This is the error that keeps appearing for all three of these in my CBS logs which seems to be causing the rollback and the "undoing changes" message:

2014-05-14 16:35:08, Error      [0x01803e] CSI    0000000e (F) Failed execution of queue item Installer: CSI HTTP Advanced Installer ({86fee01a-954a-11df-bc0c-cea7dfd72085}) with HRESULT HRESULT_FROM_WIN32(1009).  Failure will not be ignored: A rollback will be initiated after all the operations in the installer queue are completed; installer is reliable (2)[gle=0x80004005]

What is this CSI HTTP Advanced Installer and why is it failing? Also, here is a screenshot of my partitions:

I can see that the system reserved partition has no space left, but I can't seem to extend that any more than it already is. There just isn't an option to resize it, unlike the other partitions.

And I already have a case open with Support, but they're not helping at all. I was literally told just to ignore the update and hide it in Windows Update, even thought this same problem is causing my Windows 8.1 Pro upgrade to fail, which I'd really like to get installed.

Thanks in advance to anyone who has some insight on this whole dilemma.

The last two times I have attempted the manual install of KB2919355, it appears to succeed until the very end when I get the "we couldn't complete updates, undoing changes" message. On both of these occasions I have gotten error code 800F0922. In between I have attempted an to install via Windows Update and got a different error code (80246007). I have been trying to install this update for over two weeks now, have tried everything suggested in the forums and what little is available through the MS Support site all to no avail. Words cannot describe the frustration level generated by this POS update.

I'm getting this error on my laptop however my desktop which was a clone of the laptops build installed fine.

I have no VPN clients installed and I just increased the System Reserved Partition by another 200MB. The update still fails with this error code:

Installation Failure: Windows failed to install the following update with error 0x800F0922: Windows 8.1 Update for x64-based Systems (KB2919355).

Windows update gets to 99% before rolling back.

What next Microsoft?

PS - Your above link to Microsoft support does not work

Still getting error 0x800F0922 on my desktop while attempting to install KB2919355, KB2961851 and KB2962123.

I don't use any VPN Client and tried all the solutions from the previous thread, including the System Reserved Partition increase to over 1GB. Like mentioned above, the update goes to 99% before rolling back.

Weirdly the 8.1RT version installed just fine on my Surface.

I have tried installing the update so many time, every time same error. I have no VPN clients installed  in my system and i think i have plenty of GB spaces in C drive, I'm just a frustrated windows 8.1 user. Making just cases won't help us get serious about the problem cuz even after complete reinstall of windows and then installed all the required KB updates & the results was same error  0x8000F0922.
