'Atomic Os', and 'Arrange Startup'

Atomic Os

Atomic OS is a responsive Web 2.0 operating environment and development platform. Based on AJAX techniques, it emulates/provides standard operating system features including a command-line shell, interpreter, filesystem, database access and GUI services. But even this is an inadequate description. It's multi-platform for one -- all it needs is Firefox -- and it's rather portable for another. No server is required so you can carry it on a USB key, send your applications to friends, employees, and workteams via email.

Arrange Startup

A lot of programs are loaded into the memory of your PC at startup, which noticeably lowers overall PC performance. Some of the programs are necessary for normal functioning, and the rest of them can be easily removed from the startup list. Arrange Startup classifies all of your programs that are executed at startup as system programs, suspicious applications that can be viruses and the programs that are not necessary for startup. It happens very often that the applications that can be executed when needed, form part of the startup list wasting hardware resources after each startup.
