Edit re Windows 11: I'm changing over to a computer with Windows 11, so I need to answer the same question again for that. I haven't repeated all the in-depth research, but here's what I've found for Windows 11:
DOS command net user and Windows Computer Management > System Tools > Local Users and Groups > Users still show the guest account. In the latter, it still has the property "Account is disabled".
Control Panel > User Accounts no longer has Manage Accounts, so I don't see where to see anything about a guest account in Control Panel.
The MS documentation Guidance for accounts on shared PCs has been updated to say it applies to Windows 11.
BUT the page no longer says “We recommend no local admin accounts on the [shared] PC to improve the reliability and security of the PC.”
Because of the last point above, I don't know what to think. The doc has been updated to apply to Windows 11, but the most crucial piece of official advice not to use a guest account has been removed. Argh! So although it would be helpful to have a guest account on this new computer, I'm going to continue to not have one.
If anyone knows any better about what's going on with this in Windows 11, please post a comment or answer about it.
The short answer:
There is a guest account in Windows 10, but it's not suitable for use on a standalone computer.
In other words:
If your computer is not part of a network, then no, you cannot have a guest account.
The long answer:
As of Windows 10 v 1607, the guest account became part of the configuration of “shared PC mode” [Microsoft, TechTarget, [Windows Club](https://www.thewindowsclub.co
