I have posted on other tech web sites some useful information some may not know about Windows 7 and wanted to post here. Feel free to copy to another forum here if you wish to share with other 3D software users. I have been told more than several times on other sites it was useful and they did not know, so hope it helps someone else too.

Windows 7 version details -

As most know, they have read about the main differences between Home, Professional and Ultimate. However, MANY tech articles have failed to mention two critical differences between these versions.

First, the Home version is limited to only 16GB of RAM. You must have Professional or Ultimate to take advantage of more, which goes all the way up to 192GB for a RAM limit.

Second, the Home version is limited to a single CPU and will not see multi-CPUs. Only Professional and Ultimate will see more than one. I have a Mac Pro with duel CPUs andhave verified this. NOTE: this is not to be confused with multi-cores as it will see a multi-core SINGLE CPU just fine.

Installing went well for me on both the "Upgrade" and "Full" versions. Microsoft still has a VERY annoying way of doing a "clean install" for those with the upgrade version. Check out the WinSuperSite for how to do a clean install with upgrade.
