Use batch file to change PC name-CodePudding

So I'm trying to change my PC name using a batch file but when i run this code as administrator:

set /P PCNAME=Please enter Laptop Name:
set PCOLD=hostname
WMIC computersystem Where Name="%PCOLD%" Call rename "%PCNAME%"

It gives this error message: "No Instances available"

and if i replace "%PCOLD%" with hostname it gives this error message:

WMIC computersystem Where Name=hostname Call rename "%PCNAME%"

"ERROR: Description = Invalid query"

CodePudding user response：

Wmic ComputerSystem where Caption='%ComputerName%' rename example
