Most privacy-invasive tracking and data collection services are removed.
Custom configurations like the Sasnet build or similar community projects typically target specific performance bottlenecks:
Drops system-level telemetry and unnecessary background daemons to lower CPU utilization. Key Technical Changes in Modified ISOs
If you're interested in Windows 11 Pro for business or professional use, consider the following:
: It typically strips out pre-installed apps like News, Weather, and various Microsoft Store "junk" that consumes RAM and CPU cycles in the background.
Gamers looking to squeeze every possible frame per second (FPS) out of their hardware benefit from fewer background interruptions, reduced micro-stutters, and optimized RAM allocation.
While the promise of a lightweight Windows 11 is tempting, using an unofficial ISO like the SasNet version carries severe risks.
According to the developer's page, the 25H2 ISO image is extremely barebones. It contains only the most essential system components: Store, Settings, Calculator, Notepad, Paint, CMD, Run, Regedit, Terminal, Explorer, Control Panel, Firewall, Component Services, Computer Management, Performance/Resource Monitor, Services, Task Manager, PowerShell, and Search. Many common Windows apps and features have been entirely removed, including Internet Explorer, Microsoft Teams, Widgets, and Windows Security applications.
Download the official Windows 11 ISO file directly from Microsoft's website.
The result is an installed system that reportedly uses just at idle, compared to Windows 11 Pro’s typical 2.5–3.5 GB.
The ISO file is usually significantly smaller than the official ~5GB+ Microsoft ISO.
Many applications expect certain Windows components to be present. Removing things like the Windows Store, Edge WebView2, or Defender’s security center can cause:

The Windows 11 Pro Lite-Sasnet ISO represents the eternal conflict in PC computing: performance versus security. For a dedicated gaming VM on an isolated machine with no personal data? Maybe. For your daily driver that holds your banking, emails, and family photos?
