It actually does work, but it needs a small work-around
Please copy/paste following code in an admin command prompt, note that there is a enter/space at the end of the code. I added this so you would not have to enter the last command separately from the rest, if however this enter/space doesn't come with the rest then just press enter when the other commands are finished
systeminfo > "%USERPROFILE%\Desktop\Systeminfo\systeminfo.tmp"
findstr /v "Owner." "%USERPROFILE%\Desktop\Systeminfo\systeminfo.tmp" > "%USERPROFILE%\Desktop\Systeminfo\systeminfo.txt"
move %userprofile%\Desktop\Systeminfo\systeminfo.txt %userprofile%\Desktop
