This is just my personal experience, so it might be confirmation bias. Since I switched most of my software from installed to portable versions (about 2 years ago), my PC feels smoother and more stable.
I think it’s because portable software is kept in a folder on my separate D drive, while installed software ends up cluttering my OS drive (C drive) with lots of folders, files, and registry entries.
It’s a tricky question because it depends on the software, what’s installed, and your system setup. But here’s the gist:
Applications that are more isolated generally don’t mess with system performance as much, and portable software tends to be more isolated. Running them in a sandbox can help even more.
Portable apps also don’t clutter up the Windows registry, which can slow things down over time. This is less of a problem with SSDs, but if you’re using magnetic storage, the setup you mentioned could make a noticeable difference.
Portability doesn’t really affect system stability for me. It just makes managing things easier—like installing, updating, and backing up configurations.
I use Scoop to “install” a lot of my apps now, and it’s quickly become my go-to method for adding new software. It’s great for apps that don’t have their own update system, as Scoop handles that for me.
Scoop is great for updating command-line programs, ensuring you get the latest version from the original site.
For updating everything on your computer, try UniGetUI. It manages updates and installations for Scoop, winget, Chocolatey, PowerShell, npm, pip, and dotnet.
If you want a portable app installer, check out portableapps. It offers a bunch of apps through a single installer/launcher and has a tool to create portable versions of regular apps.
From my experience, Scoop updates GUI apps just fine too. I’ve got a bunch of GUI apps installed through Scoop, and I haven’t had any problems with updates. But yeah, having automatic updates for CLI programs is really handy. It’s one of the main reasons I started using Scoop…
A true portable app (one that doesn’t need installation and doesn’t mess with the Registry or any files outside its own folder) will definitely keep your system stable since it doesn’t interfere with your PC’s setup at all. So, yeah, for these kinds of portable apps, it works.
It also depends on the type of software. For example, something like CCleaner that interacts with the system can still make your OS unstable, even if you’re using the portable version.
but i agree with you. A good portable app should keep everything within its own folder and not mess with the system registry or the OS in general.
