However, if someone else were to use it they would likely start computing before it opened. Would this be a problem for the backup.
Don't think so, "Registry Backup" will only take longer time to make a backup!
The worst that can happen is that the "Registry Backup" freezes, because there are too many programs that start at the same time.
I used Ccleaner and Revo to reduce the number of startup items I am sure are not needed. I was told not to use msconfig.
If you use Revo Uninstaller your are removing the program.
If you use msconfig you only disable the autostart of the program, the program then still exists on your computer.
My processor is i5, 2.53 GHz.
My desktop i5 3.30 Ghz loads much faster so maybe the problem is the processor?
Desktop computers are often faster than laptop, but not always!
I think it's only natural that your desktop computer is faster than your laptop.
It also depends on the motherboard and several other components in the computer, not only cpu (processor).
