Windows 10 update error 0x800F0922 - Cumulative Update for Windows 10 Version 1703 for x64-based Systems (KB4516059)

I have a problem with installing this particular update.

I've read that it might need more space in the "System Reserved" partition that windows creates upon installation but for me there was none(!). I don't recall why or how this was done but that's the situation at the moment. To fix that i created a 600mb partition without letter and just marked it 'Active'.

I don't really think that my Windows installation understands that as the proper partition though... and I think that this should be the actual problem. I also tried running various commands that i found here and there (mostly from this resource) about this specific problem with no avail.

This is the event viewer log

So Windows will go on and try to install the updates, and then after reaching something like 96% will undo the installation and restart again.

My issue is now resolved, i think that what was missing from the puzzle was a simple chkdsk /f after creating the 600mb partition.
