PC Tweaker Uninstaller 0.8.0 — Microsoft Store apps

Microsoft Store apps are now listed and removable

Until this release the app read the three registry Uninstall views and nothing else — the same ones Add/Remove Programs has read for twenty years. Modern Windows keeps a second, parallel inventory: MSIX packages, listed in Settings > Installed apps, mentioned in no registry key at all. On a normal Windows 11 machine that is over a hundred programs an uninstaller was quietly claiming did not exist.

• Store/MSIX packages appear in the same list, searchable and sortable alongside everything else, with their own badge and install date.
• The Removal Confidence Score bands them from evidence Windows itself reports: frameworks and shell components are Keep, packages signed as part of Windows are Review, ordinary Store installs are Safe.
• Frameworks, resource packages and components Windows gives no display name to sit behind the existing Show hidden toggle rather than cluttering the list — the same treatment registry system components already get.
• Removal goes through the Windows package manager API, the same one Settings uses. Deliberately not Remove-AppxPackage: this app refuses to run interpreters for registry uninstalls, and shelling out to PowerShell here would have made that rule cosmetic.
• No residue step for these — MSIX removal is contained by the packaging format, and the app says so rather than running a scan that would find nothing.

One limit, stated plainly

Without administrator rights Windows gives no way to tell an app that shipped with the system from one you installed: Notepad and Spotify report identical evidence. Rather than hardcode a list of Microsoft package names and present a guess as evidence, inbox apps can land in Safe — and Safe for an MSIX package says what it means: removal leaves nothing behind, and the app can be reinstalled from the Store.

23 new tests, including live ones that exercise the real package manager on the machine running them.
