I believe it is SP1 to start with and then I added the SP3 update. No problems with that.
As to any other updates I think I installed one other one. A security update from 9/3/03. Then again I'm not sure as my Win 7 install on this desktop is from December 2010 and on my newest Dell notebook from Dec 2011. Along with all my programs installed at the same time. To long ago to remember. And as everything is working fine there is no need for me to check by doing a reinstall to find out. -- Shooter Ready--Stand By BEEP ********
