Try to follow this.
I had a hard drive with XP-SP2 that was last powered-up and updated in
June 2006.
You say that there were no more updates available for SP-2 after July
13, 2010.
Which means any updates that were made for SP-2 should remain available
for download after that date?
A few days ago I power up the hard drive and see NO SP-2 updates being
made available to me.
Where are all the SP2 updates that were being offered between June 2006
and July 2010?
I presume there were some.
(moving from SP2 to SP3 is a separate issue and does nothing to answer
my questions here)
I believe this machine has just SP2 original and nothing else except
KB909095, which addresses hibernating with more than 1GB of RAM. And
according to Belarc Advisor, this machine lacks the following updates.
Maybe this list would help you.
