Launcherleaksnet Portable
The development cycle of LauncherLeaksNet is erratic. Because it lives in a legal gray area (the "leaks" aspect implies redistribution of tools without original author consent), it is unlikely to ever appear on Steam or the Microsoft Store. The future lies in community forks.
You want to test a suspicious piece of software without committing it to your main OS. You run LauncherLeaksNet Portable inside a Windows Sandbox or a VM. Because the launcher itself is portable, you can map the VM's drive to the host, saving your settings between sessions. launcherleaksnet portable
