From a stability standpoint, removing core system files can lead to unpredictable behavior. Future service packs, updates, or software that checks for genuine Windows (e.g., certain games or professional applications) may fail or crash. Microsoft also periodically released "WAT updates" designed to detect and reverse such patches, potentially causing an endless loop of re-patching and re-breaking.
