Reboot after Update necessary?

When new updated versions of WSA are downloaded either by force or automatically is a reboot necessary for the update to take effect?

Best answer by Kit

Officially, "No", but...
 
Reboot clears and reloads the kernel driver and user mode library, which normally cannot be hot-swapped.  In some cases, this can correct issues when the bug fix is in one of those two components.
 
Unless you are experiencing technical difficulties, a reboot is not necessary after an update.

Mine updated without a reboot, but I do shut mine down everynight.

Sometimes it is necessary but sometimes you can do this later on.

Yeah, I second Kit ... it's better to reboot. In my case, having Vista Business, I noticed that some old WSA drivers have been persisting in windows/system32/drivers folder until reboot.
