win 10 version 1607 to 1703 upgrade failure code 0xc1900200

On one of my computers the windows update displayed an option for an early windows update.

This update failed with error code 0xc1900200.

The size of the partition is 100 MB.

One computer that has already been upgraded has a post upgrade partition size of 100 MB. It was a windows 10 iso clean install of 1607 followed by a Microsoft upgrade assistant upgrade.

Apparently 100 MB does not equal 100 MB if the drive manufacturers are different????

These are the links that I have come across so far in looking for a solution so far.

1) Has anyone encountered this update error 0xc1900200 from 1607 to 1703?

2) Short of clean install what method have you used to update?

3) What other options are there to upgrade if your files are not yet backed up?

These are some others that I just found looking for a solution without clean install and without risking files:

Again i don't know whether these are applicable or not applicable to this upgrade error 0xc1900800 as that is an all inclusive type error.

In this link I did not find any information on safety or risk to files:

It has been confirmed that the recovery partition is of insufficient size for the windows 1607 to 1703 upgrade.

2017-04-06 05:03:00, Info CONX CFreeSystemPartitionDiskSpaceChecker: checked InsufficientSystemPartitionDiskSpace, found HardBlock.Not enough space on partition [\\?\GLOBALROOT\Device\HarddiskVolume2\] Required: 15 MB. Available: 6 MB.

Diskpart can be used to expand this partition.........harddisk volume 2.

The files are not backed up.

Can diskpart be used without placing the files at risk?

If not what other software can be used that keeps the existing files safe on the same drive?
