Post CU Startup fails but Restart OK

Sorry about the images; still finding my way through the correct options etc.
Rt Click Start button brings up


PowerShell(Admin) plus extension brings options list;


Both images are .jpg files. Hope it's second time lucky

Now disabled enhanced uploading, so try again.
Two images both .png
Rt Click start button produces list;


Select PowerShell(Admin) after adding powercfg /? to prompt produces list of prompt extentions,


Hope this attempt works

Sorry for delay replying - had to be away from PC

Did as you recommended.
Was somewhat allarmed after adding powercfg -h off after prompt and then hitting Enter to find it just launched the prompt and the next line.
Repeated twice more with same result.
In the hope that the hibernate had been deleted I close down all activities and Shut Down the PC.
Then switched on using power button on PC and hey presto it was full start (i.e. the problem didn't occur and I was able launch my browser.
I will repeat Shut Down and Start several more times and report back (probably tomorrow).

Many thanks for your help and patience.

Yes; in a number of ways.

I accessed the Ten Forums site Open Command Prompt in Windows 10

and tried a number of the options. In all I could get a command prompt C:\WINDOWS\system32>
The guide is very clear and informative.

I also addressed the question of Win+X menu. Here again a very guide from Ten Forums
Show Command Prompt or Windows PowerShell on Win+X menu in Windows 10

Just above the Contents is a note which answers one of my questions;
Starting with Windows 10 build 14971, Windows PowerShell will show in the Win+X by default now instead of Command Prompt.
I have now changed Settings to show Command Prompt instead of PowerShell. Win+X now appears as follows;

I may never need to use command prompt again but at least I'm now better able to navigate W10.

Startup continues to complete satisfactorally.

Thank you once again for excellent support.

I tried this procedure but shutdown settings had only two option 'Sleep' and 'Lock'.
