Creating a better update table statement

Question

Hello,
I have the following update table statement that I would like to make more effecient. This thing is taking forever. A little background. The source table/views are not indexed and the larger of the two only has 150k records. Any ideas on making more effecient would be appreciate.
Thanks.
