This is the biggest win. By removing the Desktop Window Manager (DWM) tweaks, telemetry services, and UWP app hosting, the Ultralight version leaves nearly 1.2GB of extra RAM for your browser or lightweight games.
One of the biggest selling points for privacy advocates. These builds typically disable all Microsoft data collection, activity history, and targeted advertising services. No phoning home.
Most Ultralight ISOs disable Windows Update permanently. Build 19045.5198 might be the base, but you will likely never get Build 19045.5200. This means:

Assuming you accept the risks, here is the safest methodology to test if it is "better" for you. This is the biggest win
Step 1: Verify the Hash (Crucial) Download from a trusted group (e.g., Ghost Spectre, Tiny10 by NTDEV, or ReviOS). Load the ISO into VirusTotal or check the SHA-256 hash against the community forum. Malware-infested "Ultralight" ISOs are common.
Step 2: Create Bootable USB Use Rufus (not Windows Media Creator). Select MBR (for legacy BIOS) or GPT (for UEFI). Write the ISO.
Step 3: Disable Secure Boot (Temporarily) Custom ISOs often use self-signed bootloaders. Enter BIOS → Secure Boot → Disabled. Enable "CSM" or "Legacy Boot." Build 19045
Step 4: Clean Install Only Never "Upgrade" an existing Windows install with an Ultralight ISO. Boot from USB → Custom Install → Delete all partitions on the target drive → Click Next. This avoids driver conflict ghosts.
Step 5: Post-Install Actions
