How to Fix Error - After Windows Updates, system is slow, doesn't shut down properly and seems to run better in safe mode?

After Windows Updates, system is slow, doesn't shut down properly and seems to run better in safe mode

The other night my laptop upgraded windows 7 home premium 64 bit then the next day it stopped working properly.
 I noticed that in the windows update the upgrade was still listed as being available, so I re-ugraded it and now it works a little better but
still very slow and clunky.
  It won't shut down properly in regular mode but it works a little better in safe mode.
 Also, when I try to run a memory check from bootup repair options it just freezes on a dark screen.
 Is there anything I can do to fix it
or do I have to re-install windows and if so is there a way to download windows so that I can re-install?
