That doesn't work. There was a thread about it.
It only updates all of what ever tab is open.
The joke was it should be called "Update Some Stuff"
But relevant to the OT and CCC.
All you need to do is download once to one computer. The CCC download folder can easily be copied and moved to the new machine. When you run the CCC from the new machine it will not have to download those files again unless something was out of date. It will use those files to install everything.
And as said above most smart people keep all software download files on a back up drive.
Sure it takes a bit of time to get everything up and running but it's not like your chained to the chair. I will always be doing something else,, even reading a book or cooking dinner while the slower programs install.
I also recommend re booting after a few installs have completed. Many ask for this but even the ones that don't it cannot hurt.
You can put that laptop up on Ebay, you'd be surprised what someone might pay for it. Like I have 2 laptops right now that parts would be nice to have. One the keyboard is shot, another was dropped and the case is cracked.
What exactly was the laptop?
