Disk or partition space is insufficient

[admin]

Thank you Admin for the info.
It allowed me to kill two birds with one stone.

A) The system partition had 0 free space (of 100MB).
I was surprised that you needed to write in it. So I wondered how many other apps do the same. It looked like a bad idea to delete anything without knowing the details.
So I opted for a different approach. I resized the partition.

- First cloned the disk with Acronis True Image 2016
- Using the cloned disk I resized the partitions using EaseUs Partition Master, shrinking the boot partition so as to have some free space to enlarge the system partition.
After doing this I could clone without errors

B) During March I was unable to install the cumulative march update for windows 10 pro.
The update proceeded until 94% then rolled back stating that it could not finish with a vague error code.
This was repeated every two or three days.
As soon as I have enlarged the system partition I guessed that it could also be the reason of the failed update. So I retried the update immediately and this time it finished.
At the end the system partition was 35KB bigger than the original 100MB.
The error message was totally misleading and I found the solution as a collateral benefit of your hint.

Thanks again and regards
