Microsoft has released build 2142 (the latest build internally) to external beta testers at it's Windows Beta Web site. This build is not Release Candidate 2 but Microsoft have released this interim update alongside 2138 to testers which will proove not only confusing but troublesome for testers wanting to provide feedback on Windows XP SP2.
With a release of an interim merely days before the expected RC2 release this only spells bad news for a possible delay of RC2...again.
As we posted before the build string is 2142 (xpsp.040528-0019).
More news soon.
