THE OFFICIAL BLOG OF THE SBS "DIVA"

Last week we updated KB948343 to reflect some changes we’ve made to the IDT/SigmaTel filters that block Windows Vista SP1 from being available to folks running some versions of IDT/SigmaTel drivers we’ve flagged as problematic:

IDT/SigmaTel

·         For x86-based computers: Sthda.cat - published 12/17/07 or earlier

·         For x64-based computers: Sthda64.cat - published 12/17/07 or earlier 

IDT/SigmaTel

·         For x86-based computers: Stwrt.cat - published 12/17/07 or earlier

·         For x64-based computers: Stwrt64.cat - published 12/17/07 or earlier

Exceptions for IDT/SigmaTel drivers were made on certain models of Dell, HP, and Sony computers because these drivers were updated to address this issue before the 12/17/07 publish date. 

If the Sthda*.cat or Stwrt*.cat files exist on your PC AND have a modified date of 12/17/07 – the Windows Vista SP1 block filter is not applied and Windows Vista SP1 should be offered to you via Windows Update.  

If no *.cat files exist we look at specific versions (mainly on OEM PCs such as Dell, HP, and Sony) that have the fix that was made prior to 12/17/07. If the driver does not have that fix, Windows Update will not offer Windows Vista SP1 to you.

At the end of this week, Windows Update will begin providing updated drivers for some OEM PCs running IDT/SigmaTel drivers. Those who receive these updated drivers will no longer be blocked by Windows Update from seeing and installing Windows Vista SP1.

Those who do not receive these updated drivers on Windows Update and remain blocked from installing Windows Vista SP1 need not to worry – we continue to work with OEMs in providing updated IDT/SigmaTel drivers to Windows Update.

Please reply to this post if you have any questions.

Sincerely,
