Windows 11 Pro Lite v24H2 Build 26100.6899 by Ghost Spectre

Ghost Spectre’s Windows 11 Pro Lite (24H2, Build 26100.6899) is an unofficial, third-party Windows 11 ISO that has been heavily trimmed and tuned to reduce bloat and improve perceived performance on lower-end machines or gaming rigs. It integrates some official Microsoft updates but removes many default apps and services; it also provides a toolbox to restore some components if desired.

1) What this software is

Ghost Spectre is an independent author/group that releases modified Windows ISOs (often called “Lite”, “Superlite”, “Compact”, or “SE” editions). These builds are not official Microsoft distributions — they are community-made images that strip out components, apply performance/privacy tweaks, and sometimes include a small management tool (Ghost Toolbox) to add or restore removed parts. Useers choose them for smaller ISO size and lighter runtime footprint.

2) The specific release: v24H2 Build 26100.6899 — what’s notable

Build 26100.6899 corresponds to a 24H2 servicing build of Windows 11 that community packagers (like Ghost Spectre) have integrated into their ISOs. In Ghost Spectre’s release notes and community posts for 24H2 builds, common items are: integration of recent cumulative updates, updated .NET Framework packages, tweaks to Start Menu behavior for some variants, and updates to the Windows Recovery Environment and servicing stack to ensure installability and updatability. In short: Ghost Spectre generally bundles Microsoft updates into its trimmed ISO rather than introducing Microsoft feature development itself.

3) What has been removed (typical “lite” removals)

The goal is to minimize footprint and background activity. Typical removals or disabled components in Ghost Spectre Lite/Superlite builds include:

Many UWP/Store apps (Microsoft Store, Cortana, Mail, Calendar, Photos, Xbox app, etc.). These can often be reinstalled via Ghost Toolbox.
Telemetry and diagnostic services are reduced or turned off to improve privacy and reduce background activity.
Windows Defender / SmartScreen: some variants remove or disable Defender (there are “with Defender” and “without Defender” builds). Removing built-in AV increases risk if no replacement is installed.
Less essential services (search indexer, remote services, some print/spool services, unused accessibility components) are often disabled or tuned.
Some builds reduce or alter backup/restore features (WinSxS pruning, fewer restore points) to shrink disk usage, which reduces recovery options.

4) Performance tweaks and optimizations

Ghost Spectre builds typically ship with a collection of registry and service tweaks intended to prioritize responsiveness and gaming performance:

Optimized pagefile and service startup profiles, disabled unnecessary scheduled tasks.
“Performance mode” and privacy optimizations that reduce background I/O and CPU usage.
Use of compression and compact integration techniques (to reduce ISO size and on-disk footprint).

5) Recoverable components and Ghost Toolbox

Ghost Spectre commonly bundles or offers a Ghost Toolbox that lets users restore some removed components (for example, reinstall Microsoft Store, OneDrive, or Defender where applicable) and toggle tweaks. This tool is important because many users want the light OS but also occasional access to UWP apps.
