Thanks, don’t know how I missed the portable version. Guess the regular version has been on the old HDD so long that I never checked to see what else is available. I'll give the portable version a try & put it on a USB thumb drive.
On a separate note -
With my old HDD installed I frequently notice that the “Tweaking.com” icon is in the system tray. I click on the icon & Exit the program, but it shows up again, probably after restarting the PC. It’s never really bothered me, but I’m puzzled why the icon keep showing up. How do I stop this from happening?
