To achieve such extreme performance gains, custom build developers aggressively strip components from the stock installation. What is Kept?

If the risks outweigh the benefits, consider these legitimate alternatives:

: The side-by-side component store and update infrastructure are entirely expunged. This prevents the system from automatically patching vulnerabilities or updating to newer Microsoft builds.

Deep-stripping targets large components that standard users rarely interact with. This includes removing native printer drivers (outside basic IPP printing classes), language packs, accessibility tools, and recovery environment frameworks ( WinRE ). Deleting these components shrinks the install.wim or install.esd file, leading to the rapid installation speeds characteristic of lean ISO images. The Meaning of a "Verified" Custom ISO Build 19045.5198 out to RP & Release - Microsoft Q&A

Should I include a section regarding Windows Updates?

The search keyword refers to a highly optimized, custom-built third-party operating system deployment based on the official Microsoft Windows 10 22H2 build 19045.5198 . Often distributed as a debloated alternative to stock installations, an "Ultralight" ISO targets legacy computers, low-spec hardware, and specialized gaming setups by removing unnecessary background services, telemetry, and pre-installed system apps to compress the operating system footprint down to roughly 1GB of RAM consumption and 4GB of disk space .

The system creator has successfully pre-applied underlying system fixes—such as the motherboard activation bugs and cloud copy patches introduced natively in the original Microsoft Build 19045.5198 update.

Typically, the Windows Store is removed. If you rely on it for apps or games (e.g., Game Pass), this ISO may not be suitable.
