Different installation media types and registry conflicts
Hi, I've been using an installation of PortableApps, which is located on an External USB3 Hard Drive. This installation is a 'working installation', which I use to download and evaluate individual apps, with the intention of eventually placing a select subset of apps on a USB Flash Drive.
I also use this External USB3 Drive installation to run apps which I may use only occasionally, and thus prevent unnecessarily clogging up my Windows registry with local application installations.
