Installation of the optimized client is very easy.

Simply copy all files in this directory to X:Program Files\BOINC\projects\setiathome.berkeley.edu folder.
There is a file called "app_info.xml" included that will make BOINC use this client automatically.

To use it, exit and re-open the BOINC Manager if you're running it in single-user mode, or re-start the service if you're using service mode.

That's it, you're done! You can open your task manager to see that it's really the new optimized client crunching your WUs.

BOINC will tell you that it found app_info.xml and is using an "anonymous platform". 

You can find updates, instructions and source code here:

Happy crunching!
