title: Does .NET Framework 3.5 SP1 require restart?
body: <p>We have a production machine and are trying to slowly introduce some 3.0 and up features on our web application. 3.5 is installed but I would like to upgrade to SP1, I would just like to know if it requires a restart of the machine in the end so I can schedule some down time.</p>
  
  <p>Thanks!</p>
  
  <p>EDIT: so it did require the restart, thanks guys for the answer...but the hosting company didn't give us the rights to do so...LOL</p>
