Windows 10 upgrade ready - blocking system

[sargan]

PC running W7 64 bit

I had my PC set to download W10 upgrade files in background only.

Today in middle of some other work - it suddenly started to upgrade my PC !
I stopped that .....
W7 recovered OK

I followed advice to remove KB3035583 and this did remove the white W10 ready icon in task bar
However if I go to Windows Update ... it shows:
"Your upgrade to Windows 10 is ready ... you need to restart your PC"

I have used cleanmgr.exe to remove temporary installation files ..... but no change.
If I go to 'Check for updates' so I can hide KB3035583 from future updates .... I can't access this as I get the message "Windows update cannot currently check for updates, because you must first restart the computer so that a previous installation can be completed"

Reboots do not clear it.

Tried restore to earlier version ... restore fails, unable to extract file. (never had a restore to earlier point work)

All restore points failed to work.
Appeared that it was stuck in a part way through W10 install position.

Anyway I found a simple fix .... and for anybody else the solution is to use the GWX10 control panel.
A great free utility to resolve or prevent W10 upgrade.

"GWX Control Panel is a free program that you can use to do the following on Windows 7 and Windows 8:

• Remove the "Get Windows 10" icon that appears in your notification area.
• Prevent your Windows Update control panel from upgrading your computer to Windows 10.
• Prevent your computer from secretly downloading Windows 10 installation files.
• Detect and remove the hidden Windows 10 installation files if they're already on your PC.
• Optionally monitor your computer for unwanted Windows 10-related settings and files. (New in version 1.6.)

GWX Control Panel really works, is safe and easy to use, and gives you the option to re-enable the icon and upgrade notifications if you're ever ready to move forward with Windows 10. "
