I downloaded partition wizard which is a free use and download program.
With this I was easily able to double my hard disk partition size from just over 500Mb to 1Gb as from what I can see KB 5034441 fails to install as most hard disk partitions as installed with Windows 10 that I use, are too small for this update and this is why this update installation fails.
I have plenty of additional storage on my system, so it was a no brainer.
It takes about 35 minutes on my system for the partition size to be increased which is a little worrying however be patient.
Once the partition size was changed and after the necessary reboots my system works perfectly, and KB 5034441 installed no problem first try.
It's still amazing to me that Microsoft can issue a mandatory update that simply does not work using their own basic systems and we have to go through this hair-raising experience to fix what is simply something they created and did not adequately test.
I hope this helps those that have had the same experience as me.
