Windows SharePoint Services V3 and Microsoft Office SharePoint Server 2007 are now be able to get updated to the latest available bits with February CU.

Side Notes:
The sizes of the packages are smaller than in the past (June 2010 CU and earlier). This is because you need to have SP2 installed so that not all fixes between SP1 and SP2 are necessary to ship with each CU.

KB articles are having sometimes a bit delay but the link should work when these are available.

WSS:

Download and installation information:

• Install SP2 for WSS and MOSS SP2 and Language Packs if not yet happened.
• Do you need more information about the SP2 update? Please check out the blog of my colleague Steve Chen http://blogs.technet.com/steve_chen/archive/2010/04/22/all-about-updating-wssv3-and-moss2007.aspx

After applying the preceding updates, run the SharePoint Products and Technologies Configuration Wizard or “psconfig –cmd upgrade –inplace b2b -wait” in command line. This needs to be done on every server in the farm with SharePoint installed.
