After completing the changes I did a Disk Clean.
The Windows 10 would not reboot fully after this - it stuck on the user login page just before adding the fields to log in.
It was restored using the Snapshot - good job it was recommended before using Diskpart.
Subsequently the system has restarted several times - the Snapshot was removed - the Control Center no longer shows the Snapshot icon.
After at least two complete shut downs of the computer - unplugged from the mains supply
- when restarting Windows: the Windows 10 Configuration - General - still shows a Total Size of around 87G - with 4.7G reclaimable.
I attach a relevant screenshot
However there is an issue with the hard disk - see below
There are two unwanted Image files (2MB? Each expandible) as well as the wanted on 184GB Image file.
The unwanted files could be causing a problem - how can they be removed?
There are other unresolved problems ...
For all of the past month I have been unable to load updates to Windows 10.
The Windows 10 update apparently downloads - and this - and/or the following installation update - sometimes seems to crash the iMac - I lose WiFi connection with a spinning coloured ball - this has happened at least 6 times...
I have yet to succeed with an update over the last month. To avoid repeated crashes of the system I inhibited Windows 10 updates.
It has been surmised that the crashes and problems might be due to the apparent lack of available capacity on the Virtual drive - hence the current investigation.
I do not dare to use my Windows applications - ProShow Producer and Pictures to Exe - these are both Audio Visual show creation programs which when compiling will create very large files - well beyond the limits I apparently have...
