Change Windows Password and SQL Instance Windows Authentication Credentials

I ran across this issue today when I changed my network password and then all of the sudden I couldn't get my SQL Instance running nor could I log in to SQL Manager with my windows authentication because it was using cached credentials from my previous password. Fortunately it was a simple fix.

Open Services and find the instance service (Right click Computer and goto manage) then right click and find properties. I simply supplied my new password and viola. Hopefully this helps someone else.
