Final answer:
The cmdlet that can be used to temporarily prevent users from signing in using the account name Ignis without deleting it is Disable-LocalUser.
Step-by-step explanation:
The cmdlet that can be used to temporarily prevent users from signing in using the account name Ignis without deleting it is Disable-LocalUser. This cmdlet allows you to disable a local user account, which means the user will not be able to log in. Here's an example:
Disable-LocalUser -Name 'Ignis'
This will temporarily prevent the user 'Ignis' from signing in.
It's important to note that disabling a user account does not delete it. The account can be re-enabled using the Enable-LocalUser cmdlet.
