SharePoint Foundation 2010 is not a part of Windows anymore.
SharePoint Foundation 2010 is not labeled a Service anymore.
Both the "W" and the "S" in WSS are gone. So, using WSS will no longer work.
Windows SharePoint Services is now called SharePoint Foundation 2010.
It coincides with the other foundation products in the .NET framework.
Hence the new abbreviation SPF 2010.
Can't you see the synergy; the power of predictability?
SP 2010 = SharePoint 2010
SPS 2010 = SharePoint Server 2010
SPF 2010 = SharePoint Foundation 2010
SPD 2010 = SharePoint Designer 2010
SPW 2010 = SharePoint Workspace 2010
SPC 2009 = SharePoint Conference 2009 was about SPS2010
etc.
There are no outliers with this pattern. No races to offend, no overlapping products to get confused with, etc.
The only complaint of any consequence is that SharePoint Portal Server 2001 and SharePoint Portal Server 2003 were also commonly abbreviated SPS. Since SharePoint Server 2010 is the successor of those older versions, I actually think that using SPS 2010 is even more compelling. MOSS will be the only outlier in that sequence. But SharePoint Server 2010 is not part of Office anymore.
So, the server product that was sold on top of the platform had the following history of abbreviations:
SPS 2001 > SPS 2003 > MOSS 2007 > SPS 2010
The platform had a more sorted set of names: Office Web Components morphed into SharePoint Team Services (first actual install called SharePoint). Windows SharePoint Services (no version was typically associated with this release but it was generally accepted as 2.0) was released in 2003 followed by Windows SharePoint Services version 3.0 (to differentiate between the 2003 and 2007 releases) and now SharePoint Foundation 2010.
So, the platform itself had the following history of abbreviations:
OWC > STS > WSS > WSS v3 > SPF 2010
While I agree that this last sequence is bad and I get why some want to use WSS v4 (or some other odd derivation: SS, WSF, MSF, etc.), see the top of this message. Both the "W" and the "S" are gone so WSS won't work anymore!
HTH,
