I fix a lot of computers and I always use the Piriform utilities to perform basic maintenance. It would be nice to have these installed on my Portable Apps flash drive, so I don't have to download and install the software for each computer I work on.
Apps: CCleaner, Defraggler, Recuva, and Speccy.
Licence: Freeware

Piriform provides portable builds of each app (example here: http://www.piriform.com/ccleaner/builds ).

John has sent emails to Piriform about the inclusion of their apps on PA.c, however I do not know the status. This has been requested many times though, so we're trying.
In addidtion, there are Development Tests here in the Beta forums: CCleaner, Defraggler, Recuva and Speccy. Even the old ones of Nathan9222 work well but some (Defraggler/Recuva) need copying the base app to the App folder.
They once provided a download function that is now broken, maybe because the location switched. CCleaner Portable still downloads the latest version and checks for updates on every start.
And Speccy Portable is maintaind well...
Why not just use Piriform's portable ones?
I do this. But then you have to update manually. Having PA versions would mean that you could get your updates via the software update app.
No, actually I use the launcher from the beta forum. I used to use the official portable at home, until I discovered Ninite. Still, I have to update that manually as well.
