UniGetUI 2026.3.4 Adds Installer Hash Checks, Update Controls and WinGet Fixes

It's a point release, but people who use UniGetUI as their main Windows update tool will notice the changes.

What 2026.3.4 adds​

Devolutions summarizes the build as one that adds a docked package details panel, a Manager Health page, and two new extensions: Agent Skills, and Xcode on macOS. It also adds new options for updates, notifications and shutting down, and fixes many update, display and performance bugs. Devolutions' own release-notes page lists 11 features, 9 improvements and 10 fixes.

The GitHub release notes describe these user-facing additions:

• Docked package details panel. It can stay open next to the package list on the Installed, Discover and Updates pages and follows whichever package you select. You can open it from the footer, from the right-click menu, or with Ctrl+Shift+D (Cmd+Shift+I on macOS).
• Manager Health page. It shows when each package manager last worked or failed and offers repair actions. If a manager's tool isn't found, its status card links to a setup guide.
• Agent Skills extension. It lets UniGetUI find, install, and update skills and plugins for Claude Code, Codex, GitHub Copilot, and Cursor. It's off by default and lives under Settings > Extensions.
• Xcode extension (macOS only). UniGetUI added an Xcode extension on macOS 13 and later. It downloads, installs, updates and switches between several Xcode versions, and manages Simulator runtimes, after you sign in with your Apple ID. Windows users can skip this one.
• Git Repositories extension. It now shows the size of each clone and worktree and reports refresh failures more clearly.
• Horizontal scrolling. Package lists can now scroll horizontally instead of squeezing columns. Turn off Fit columns to the window in the column menu

The previous release, 2026.3.3 (October 29), introduced the Extensions area with Git Repositories as its first entry and kept extensions off by default. This release adds two more and keeps the same opt-in approach. If you never open Settings > Extensions, neither the AI tooling nor the Xcode manager will appear.

In short: most of the new features are opt-in. The details panel and Manager Health page are the two that every Windows user will see.

UniGetUI's own updates now wait for you​

The biggest change is how UniGetUI updates itself. When a UniGetUI update is ready, you can now read its release notes before installing it, then update now, update when you quit, or skip that version. You reach that screen from the update notification or from More > Check for UniGetUI updates.

Closing the app also no longer installs a waiting update by surprise: Quitting UniGetUI no longer installs a waiting update unless you choose to.

If you'd rather have automatic updates, Devolutions added an option to install UniGetUI updates automatically while it runs in the background with nothing else in progress (Windows, off by default).

Other new update and notification options:

• Quit when there's nothing to do. The app added an option to quit UniGetUI when automatic updates find nothing to install. This builds on 2026.3.3's option to quit once automatic updates had finished.
• Notifications that stay up. On Windows, update notifications can now stay on screen until you dismiss them.
• Shut down when finished. On Windows, this new item in the operations panel menu shuts the PC down after the current operations finish. A 60-second countdown appears first, and you can cancel it.

The shutdown option is meant for queuing a large batch of updates before leaving for the night. Because of the 60-second countdown, it won't shut down immediately, and it doesn't run unless you select it.

In short: UniGetUI no longer updates itself when you quit unless you tell it to. Automatic self-updates are available on Windows but are off by default.

Package update options and fixes​

Two new per-package installation options cover common update problems:

1. Skip major updates. You keep getting minor and patch releases but don't move to the next major version. This helps when a major release changes licensing, a UI or plugin compatibility.
2. Uninstall, then reinstall when updated. For packages that only update cleanly from a fresh install.

The second option goes with a WinGet change. According to the GitHub notes, UniGetUI now lists WinGet updates that can only be applied by reinstalling, such as when a new version switches installer type. Those updates were previously easy to miss. The project also lists general improvements to WinGet searches without giving details.

The WinGet bug fixes:

• Fixed Steam and other launcher games being listed as WinGet packages with a permanent update.
• WinGet no longer offers an update when another installed copy of the app is already newer.
• WinGet portable apps no longer lose their command links when updated without administrator rights.
• An empty Discover search no longer returns nothing on some private WinGet repositories. Devolutions' notes list this fix alongside a restart staying pending forever after rebooting and scheduled update checks installing updates at startup.

Other package-manager changes:

• .NET Tool now uses the feeds in your NuGet configuration, including private feeds, and detects updates on Artifactory feeds. Development teams with internal tool feeds should see more accurate results.
• Pip no longer uses or updates Python environments that belong to other apps. This follows 2026.3.2, which fixed Pip updates that could corrupt the Python environment.
• Startup update checks now wait for each package manager's installed-package list. The project says this reduces load on machines with many packages.

In short: if WinGet kept showing the same update that never cleared, especially for launcher games, try this build first.

Hash checks and signer display​

The project says downloaded installers are now checked against their published hash, and the installer's signer is shown. NT Compatible described the release as hardening security by checking downloaded installers against published hashes and displaying their signer.

This is an improvement, but it has limits. A hash check confirms that you received the file the package manifest describes. It doesn't prove that the file is safe. Seeing the signer helps you spot a mismatch, but you still have to decide whether to trust that publisher. The changelog doesn't say which hash algorithms are used or what happens when a manifest has no hash.

NT Compatible also noted why this matters for a tool like UniGetUI: UniGetUI installs and updates other software, so it carries a lot of system trust by design.

You can also check UniGetUI's own downloads. The GitHub release includes a checksums.txt asset with SHA-256 hashes. NT Compatible pointed out that you can use it to cross-check everything yourself. To check a Windows installer:

1. Download the installer and checksums.txt from the official release.
2. Run Get-FileHash .\UniGetUI.Installer.exe -Algorithm SHA256 in PowerShell, using the filename you downloaded.
3. Compare the output with the matching line in checksums.txt. If they don't match, don't run the installer.

In short: hash checks and signer display make tampered or swapped installers easier to catch, but you still need to judge whether to trust the publisher.

Performance, display and accessibility​

Two fixes address common complaints:

• Memory use. The operation history file could grow to hundreds of megabytes and use gigabytes of memory. That's fixed. If UniGetUI's RAM use kept growing on your machine over months, this was a likely cause.
• GPU use. Indeterminate progress bars use much less GPU on Windows

Display and accessibility changes:

• The window frame, shadow and corners now look right when Windows 11's rounded corners are turned off, and the Close button is centered.
• The grid and icon cards on Software Updates now show the new version number.
• Screen readers now announce tab names in installation options and operation history. This continues accessibility work from 2026.3.1 and 2026.3.2.
• On Linux, UniGetUI no longer keeps offering a self-update it can't install for .deb and .rpm installs.

In short: if UniGetUI has been sitting in your tray using more memory than expected, this release targets that problem.

Getting the update​

This release came from Devolutions. NT Compatible reports that the company, a Montreal security firm, acquired it in March 2026 and kept it open source under the MIT license. The same outlet says the build includes 66 commits from 13 contributors across 588 changed files. It also lists two install methods: winget install --id Devolutions.UniGetUI or the Microsoft Store.

Things to know before installing:

• Chocolatey users: the old package name is retired. Chocolatey's listing says UniGetUI is now published as the unigetui package. If you installed through wingetui, switch to unigetui so you keep getting updates.
• ARM64 and portable builds: the GitHub release has ARM64 builds, including a 34.8 MB ARM64 installer and a 52.4 MB ARM64 zip. Neowin lists the x64 package at about 50 MB.
• The portable build still needs Visual C++ runtime libraries. MajorGeeks notes that the portable version still requires Visual C++ dependencies, so it's not really portable. If you try to run it on a computer without them, you will get a myriad of missing Visual C++ libraries.

Who should update?​

• WinGet users with stuck updates: update now. The launcher-game, newer-copy and reinstall-only fixes address the most common sources of updates that never clear.
• Admins and teams with private feeds: the NuGet and Artifactory changes for .NET Tool, plus the private WinGet repository fix, are worth testing.
• People who don't like surprise updates: UniGetUI now asks before updating itself.
• Developers using AI coding assistants: Agent Skills is optional. Keep in mind that skills and plugins for coding agents can be as risky as any other software you install.

The changelog makes claims, not measurements. Devolutions doesn't publish benchmarks for the startup load reduction or the GPU savings, and whether this release behaves well on your machines is for your own testing to show. Still, this is a solid update for anyone who manages Windows software through UniGetUI.
