Maybe it’s already there, but since I haven’t notice any speedup in boot process, I don’t think it’s already implemented.

When eBoostr service/driver loads, it should cache boot files at first to maximize boot process. eBoostr could have some own statistics how files are loaded during boot, or it could you use information in C:\Windows\Prefetch\Layout.ini.

When boot process is complete and user is logged in completely, eBoostr could remove those boot files from cache to free cache space for normal applications.
