PortableApps really needs Driver Manager, Driver Genius or similar driver utility. Although I've never found it necessary to have drivers monitored and regularly scanned/updated which would need a resident installation, it's a great time-saver on new builds and OS upgrades so perfectly suited to the PortableApps armoury. There are dozens on the market, but only the paid ones are really worthwhile.
I used Driver Genius up until Windows 8, but Driver Manager looks a better bet now and has some sort of endorsement/connection with Symantec. I read a group test recently that put Driver Reviver top of the pile (despite the tacky name) although neither of the above were included in the test.
