When you install a stock Windows 8.1 ISO, you often have to spend hours uninstalling useless apps. A Lite ISO is "clean." It contains the OS, the drivers you need, and nothing else. It is the purest form of the Windows desktop environment.
Minimizing UI animations reduces GPU and CPU load.

Why this is better: A cheap laptop with 4GB of RAM can actually run a web browser and Microsoft Office simultaneously. On Windows 10, that same hardware would freeze.
Think of the ASUS Eee PC, Acer Aspire One, or Dell Latitude D630. These machines have Intel Atom N270/N450, Celeron 900, or Core 2 Duo CPUs, 2-4GB of RAM (non-upgradable), and a slow 5400RPM HDD. Official Windows 10 is a slideshow; Linux might have driver or compatibility issues. Windows 8.1 Lite x64 boots quickly, runs Firefox with uBlock Origin smoothly, handles LibreOffice or Office 2007, and even plays 720p YouTube via h.264 hardware acceleration (if the GPU drivers are preserved).

Before committing to a modded OS, consider these safer alternatives:
Official Windows 8.1, even on a clean install, runs dozens of background services: Windows Defender, SuperFetch (now SysMain), Print Spooler, Windows Search, Error Reporting, Telemetry, and a host of scheduled tasks. For a modern PC (8th-gen Intel or later, SSD, 8GB+ RAM), these are negligible. But for a 2008-era Core 2 Duo laptop with 4GB of RAM and a spinning hard drive, those services are a death sentence. Why this is better: A cheap laptop with
Windows 8.1 Lite x64 takes a scalpel—or sometimes a chainsaw—to the OS. A typical "Lite" build might:
The result? An installation ISO that shrinks from 4.5GB to sometimes under 1.5GB. Idle RAM usage drops from ~1.2GB to as low as 400-600MB. The number of running processes falls from 70+ to under 30. On a mechanical hard drive, boot times can drop from 90 seconds to under 25 seconds.
