Quick Report

Microsoft released KB5121003 for Windows 11, adding long-requested features including dynamic file sizing in File Explorer and expanding the Low Latency Profile to more applications. File Explorer now displays files in KB, MB, or GB depending on size, replacing the old method of showing all files in kilobytes.

The Low Latency Profile boosts CPU to maximum frequency for 1–3 seconds at app launch, resulting in about 40% faster launches for Microsoft applications like Edge and Outlook, and up to 70% faster launches for system elements like the Start Menu and context menus. Windows Search also received improvements for typo tolerance and better understanding of incomplete searches, with improved focus on relevant local results rather than web search.
