Anyone else tried this on a Intel Pentium D??

This "dual core" fix is not for improving dual core performance, but for preventing crashes caused by dual core CPUs (mostly from AMD) when they change power-saving states. AKA change their CPU operating frequencies to save power. It does nothing to improve performance, XP already schedules tasks across cores without the fix.

You DO need the fix if you are getting crashes in XP because of your dual core CPU.

As for the difference between Vista and XP, Vista is running so many craplets in the background it needs enhanced dual core support just to run as fast as XP. :| Compare Vista performance on single and multi core CPUs if you think this is a joke.

Here's a good article about what this XP dual core issue is really about:

But then why are people getting performance increases??

This guide is not for XP 64-bit btw. The update doesn't apply (and there isn't a 64-bit version, I checked) and the reg entries aren't there in the 64-bit version too. Just wanted to let you all know ;) Thanks for the guide tho, I did hear it's done wonders for my friends.

This is what I read of the MS website, here: http://support.microsoft.com/kb/896256

SYMPTOMS

Computers that are equipped with multiple processors that support processor power management features, such as Advanced Configuration and Power Interface (ACPI) processor performance states, require Microsoft Windows XP Service Pack 2 (SP2). Additional updates are available to optimize performance and behavior on computers that are running Windows XP SP2. Without these updates, computers that are equipped with these power management-capable, mobile, dual-core processors may experience decreased performance or unexpected behavior.

That red word leads me to think that there isn't any performance to be gained by doing these steps.

i dl'ed the ms fix and i got an error. I have a p4 w/HT, created the registry key and modified the boot.ini

i'm actually gonna restart right now to see if there's a difference.

when i built my bro's AM2 Rig, i believe i installed the AMD drivers, the Windows fix, AND the dual core optimizer (one game even required it). so i dont believe its harmful. every game runs fine on it, except he's having issues with steam games (online only). Wish i knew why.

    • EU says Meta must restore rival chatbots' access to WhatsApp

      By Hamid Ganji · Posted

      EU says Meta must restore rival chatbots' access to WhatsApp by Hamid Ganji The European Commission has ordered Meta to restore third-party AI chatbots’ access to WhatsApp after the tech giant decided to block them from operating on the popular messaging platform. After Meta banned rival AI chatbots from operating on WhatsApp, the European Commission launched an antitrust investigation to determine whether the company had abused its market dominance. As a result of Meta’s decision, third-party AI chatbots, including Microsoft’s Copilot and OpenAI’s ChatGPT, were prevented from operating on WhatsApp. At the time, Meta said it wanted to reserve the WhatsApp Business API for other types of businesses and did not allow rival chatbots to use it. This effectively prevented the WhatsApp ecosystem from being used to distribute rival chatbot services. However, the European Commission has now announced an interim measures decision requiring Meta to restore access to WhatsApp for rival general-purpose AI assistants on the same terms and conditions as before October 15, 2025. The Commission has also asked Meta to maintain that access until the antitrust investigation is concluded. The Commission argues that Meta has used its dominant market position to prevent rival AI chatbots from accessing the WhatsApp Business API. While Meta allowed rival services to return to WhatsApp by paying a fee, the European Commission still considers that arrangement to be a de facto access ban. According to EU antitrust chief Teresa Ribera, the fees introduced by Meta are so high that using WhatsApp is no longer economically sustainable for competitors. “It seems that Meta expects to leverage the vast reach and likely dominance of WhatsApp to benefit its own AI assistant and to foreclose rivals,” Ribera said. “We cannot let large digital incumbents leverage their dominance of the past to dictate who in Europe gets to compete and who gets to innovate in AI.”

      I'm fine with a little reasonable promotion of Edge, but the degree which they do it right now I consider extremely unreasonable. 
    • Microsoft AI boss no longer believes that AI will replace human workers

      By David Uzondu · Posted

      Microsoft AI boss no longer believes that AI will replace human workers by David Uzondu Mustafa Suleyman, the head of Microsoft AI, recently took back his statements concerning white-collar jobs that he gave to the Financial Times in an interview made back in February, where he claimed that AI would replace office workers within 12 to 18 months. On Monday's episode of The Verge's Decoder, Suleyman recast the technology as more like a helpmate than a tool designed to take over your job. He explained that smaller office duties will "increasingly become digitized, automated" as people generate more digital materials. During the discussion, Suleyman emphasized a "very important distinction" between "tasks" and "jobs" to clarify his previous claims. He argued that his earlier comments only referred to individual actions that people perform at their desks. Suleyman used to work for DeepMind, the research lab he co-founded in 2010 alongside Demis Hassabis and Shane Legg, before he left in 2022 to establish Inflection AI and build an empathetic digital assistant. Microsoft hired him in March 2024 to lead its newly formed "Microsoft AI" division, placing him in charge of consumer products like Copilot, Bing, and Edge. His February comments also detailed plans for Microsoft to achieve self-sufficiency with a $140 billion infrastructure budget to train frontier models, predicting that creating a customized AI will soon feel like creating a podcast or a new blog: The 41-year-old is not the only AI executive who's softened his "AI will replace you" stance. OpenAI's CEO, Sam Altman, last month used X to push back against employment panic by arguing that his startup builds tools to assist humans rather than build replacements. He had previously garnered backlash by suggesting that many modern office roles that AI might replace did not qualify as "real work" in the first place, at least when you compare desk jobs to physical, historical labor like farming.
