Windows Sidebar

The Windows Sidebar originated in Longhorn build 3683. It was kept until development reset. However, the sidebar was made available for build 5219 as a separate download,it was also included in build 5212,but not enabled by default, and was not included in 5231.With build 5308 it was included again. In Windows 7, the Sidebar was replaced with desktop gadgets starting with build 6519. Desktop gadgets were removed from Windows 8.


 * In pre reset Longhorn builds, Sidebar ran in explorer.exe, which caused massive memory leaks, thus in post reset it ran in it's own process, sidebar.exe.
