Scripts to build a trimmed-down Windows 11 image.
This is a script to automate the build of a streamlined Windows 11 image, similar to tiny11. My main goal is to use only Microsoft utilities like DISM, and nothing external. The only executable included is oscdimg.exe, which is provided in the Windows ADK and it is used to create bootable ISO images. Also included is an unattended answer file, which is used to bypass the MS account on OOBE and to deploy the image with the /compact flag. It's open-source, so feel free to add or remove anything you want! Feedback is also much appreciated.

jemalloc is a general purpose malloc(3) implementation that emphasizes fragmentation avoidance and scalable concurrency support. jemalloc first came into use as the FreeBSD libc allocator in 2005, and since then it has found its way into numerous applications that rely on its predictable behavior. In 2010 jemalloc development efforts broadened to include developer support features such as heap profiling and extensive monitoring/tuning hooks. Modern jemalloc releases continue to be integrated back into FreeBSD, and therefore versatility remains critical. Ongoing development efforts trend toward making jemalloc among the best allocators for a broad range of demanding applications, and eliminating/mitigating weaknesses that have practical repercussions for real world applications.
