Windows supports virtual desktops which is how I generally group different applications and documents that are open simultaneously. Use Windows+Tab to bring up the set of current desktops and create a new one. Windows+Control+left/right will let you move one at a time through them (though it doesn't cycle, leftmost and rightmost don't bring you back to the next).

Or you can use VMs like some projects do in my office. Closed and status saved, totally restored to the last working condition when reopened. It's convenient, though not my personal preference (also cleanly handles issues around projects requiring different versions of some system libraries and tooling).
