Windows 10 - Adding / Creating Local User Instead of Microsoft User

Back in the days (not apologizing for reminiscing) of Windows XP (or maybe even Windows 7) or earlier, adding a user is a simple process of adding a user.

With Windows 8 (I hope not 7) onwards, there seems to be a deliberate attempt to coerce (force) people to open up Microsoft accounts and create such cloud users, even when people are just trying to use their Windows computers locally (not in the cloud). Then in Windows 8, you must read the fine print and try to choose to create or add a "Local User". So a "Local User" is actually what a normal user is, in the previous Windows version - but now we have to remember to use "Local Users" if we just want a normal user on  a computer.

In Windows 10, this is much more difficult, frustrating and annoying. So previous Windows just need: Go to Control Panel -> click Users -> Add user.
But now the problem is so complicated, bordering on deceiving, I just cannot stand it and have to share this process here so that people can get help.

Step 1: Use the normal process of going to Control Panel, or searching for User, to land on this dialog below. Or Control Panel -> User Accounts -> User Accounts (not typo) -> Manage Accounts -> click on "Add a new user in PC Settings"

Then click "Family and Other Users".
Why why why they can't just say "users"?

Then click on "Add someone else to this PC"
(What if this is my family member, but they don't have Microsoft account - sic)

Don't put email address, don't click next.
Instead click "I don't have this person's sign-in information"
(Why why why - well I have this person's sign in - but I refuse to use their Microsoft account. I just want to create them as a "Local User" - phethhhh  :p  )


Finally - almost there. Still don't fall into the trap of giving your details and email.
Click "Add a user without a Microsoft Account"

Home Run !!! (Exactly the fourth / home base)
Now this is more like the usual creation of a normal Windows user.
Go ahead and give it a funny user name - as all computer users have done since the dawn of computing - instead of giving your email account.

Missing Windows 10 Start Key functionality

Beware - Windows 10 - Broken Windows Start Key functionality.
Normally, the Start button on the lower left corner of the Desktop, when pressed, will bring up a list of apps, and some tiles.

When this problem hits (out of nowhere), pressing (left clicking) the Windows Start button has no effect. Double click the Search bar next to it - still sort of works sometimes. Right-clicking the Start button reveals a text based list of thinks that you can do - including poweroff. So all is not lost, but it is very frustrating to see the normal functionality disappear. (see the image below to view the new text-based list of items when right click).



Solved - but don't know which of the following did the trick. Googling gave two solutions.
1 ) Open CMD prompt as Administrator and run:  SFC /scannow
2) Open Powershell as Administrator and run the command shown in the webpage in the image below
3) Restart the PC
All is back to normal. I did all three in sequence. Don't really know if the restart at the end actually solves the problem or all three together.
