: The version number 221290 likely refers to a specific release date (December 2022) or a customized build number based on a Windows 10 or 11 base. Security Warning

: By stripping out non-essential components, the installation file (ISO) is significantly smaller than a standard Microsoft release, making it faster to download and install.

: Most pre-installed "bloatware," including telemetry, certain Windows apps (like Maps or Weather), and unnecessary background services, are removed to free up RAM and CPU cycles.

: Custom ISOs are not provided by Microsoft. Only download from trusted community repositories to avoid malware or hidden backdoors.
