If it requires a microcode update, it's not microsoft's problem, it means the problem is in the chip. It probably happens that microsoft stumbled upon the problem, some instruction or combination of instructions they use trigger the problem. I'm sure more people run windows update than update their bios, so the best bet is to just fix it there.

Does this affect the T-series cores?

In the mobile world, people with the Core 2 Duo T5000 and T7000 need to visit Microsoft's site, while the server guys will want to use motherboard BIOSes if they do not rely on Microsoft Windows operating systems.

so do we have to update windows with this patch every time we format or is it just a one time process? Dunno whether same like 'flashing'.

What a bout laptops? Reason is i'm getting my laptop tomorrow and i don't think BIOS upgrades for laptops are all that easy to find.

In rare instances, improper TLB invalidation may result in unpredictable
system behavior, such as system hangs or incorrect data. Developers of operating systems should take this documentation into account when
designing TLB invalidation algorithms. For the processors affected, Intel has provided a recommended update to system and BIOS vendors to incorporate into their BIOS to resolve this issue.

Hardware Home: Intel Core 2 CPU error discovered and patched

Error in TLB cache in Intel Core 2 CPUs that is used to improve the speed of virtual address translations fixed.
Via The Inq: "At first Intel posted the details about these particular errata back in late April inside a Core 2 Specification Update PDF document, explaing how this error could cause memory leaks and ultimately, lead to crashes.

"We've addressed a processor issue by providing a BIOS update for our customers that in no way affects system performance. We have documented this as an errata. All processors from all companies have errata, and Intel has a well-known errata communication process to inform our customers and the public. Keep in mind the probability of encountering this issue is low. Intel documented the issue a few months ago - Specification Updates for the affected processors are available at http://developer.intel.com."

The errata inside all Core 2 processors (T series, E series, Q series, QX series and Xeon 5000 series) can appear in very rare cases, and it can result a computer refusing to accept keyboard of mouse inputs. In Windows environment, it may result with a worldly known Blue Screen of Death, while Linux'es of this world may end up with kernel panic.

In conclusion, this problem has been fixed, with BIOS updates for motherboards containing fixes after the erratum was posted on developer.intel.com. Microsoft came up with a patch that will stop errata from possibly appearing, Apple already updated Mac OS X while the Linux status is unknown at time of writing*. It remains to be seen whether the companies will rather choose to go full disclosure of every error that happens in the future"

here another article of it
by the way, could any1 upload to another website so i could update also? Because i using pirated win XP PRO?
