Script to change user name and machine name on Windows 10

Do you know of a script to periodically change the Windows 10 username &

Some badly behaved programs phone home with the username and machinename so
I just want to change them periodically since they're meaningless to me in
all ways (they're just xxx and yyy currently, for example).
What would be best is a script that changes both randomly upon reboot or
manually upon invocation.

The actual names don't matter, probably it would be just aaa, bbb, ccc,
ddd, eee, fff, ggg, hhh, iii, etc or perhaps a random lookup from a
dictionary file but it doesn't matter where the machine name and user names
come from since they serve no purpose in my single-user desktop anyway.

They're just a privacy hole waiting to be exploited.

Do you know of a script to periodically change the Windows 10 username &
machine name on demand?

Minimally tested PowerShell to set your current username to a random
name of 15 characters and to give the computer a random 15 character
name. The call to Rename-Computer will restart the computer afterwards.
Un-comment the last two lines if you want this script to actually do
anything. Must be run as an Administrative user (which is also the
account to be renamed). I ran the script on a VM and ended up with a
computer name of ict9gjhqianswd and a hostname of ahzpkl99tpk69.

If you save the script as something.ps1, to actually run it you'll need
to modify the execution policy to allow running unsigned scripts.

Use at your own risk.

function Get-RandomName {
$alpha = ("abcdefghijklmnopqrstuvwxyz0123456789" -split '' |
Where-Object {$_ -ne $null })
$newName = ""
for ($i = 0; $i -lt 15; $i++) {
$newName += Get-Random -InputObject $alpha
}
$newName
}

$NewComputerName = Get-RandomName

$userAccount = Get-CurrentUserAccount
$NewUserName = Get-RandomName

#$userAccount.Rename($NewUserName)
#Rename-Computer -NewName $NewComputerName -Restart
