My PC has recently been turning itself off and this is what the event viewer says is happening when it turns off. Does anyone know what this error is/how to fix it. I cant find anything on the Microsoft support site.

Thanks

I hope not. I cant find any info on it at all, anywhere. This thread ties in with another one i posted about my pc not booting or reseting. https://www.neowin.net/forum/index.php?showtopic=560352

I dont really know whether its a hardware issue or something to do with the software.

Hi, first post here... just been looking into the same issue on a friends laptop - vista premium, all updates, ie 7 and firefox...

read your post earlier - this laptop was shutting vista down automatically on a few sites and whenever a download was attempted. I created a new account which creates a new profile and the problem does not exist. I probably won't look further oz I have already spent a couple of hours on things like java and flash updates, browser test sites etc. so will just create a new account and transfer data... hope this helps... Many blessings... Chris ) John 3:17

Update to last post. Before I gave up on the profile I added AVG and it found a worm i-worm.vb-tc I think. AVG deleted one instance which then allowed the original profile to download file from the internet successfully. I then ran a full a scan and it found several other instances which were dealt with. Laptop is fine now. Chris :)

    • The Trump administration doesn't want you to use OpenAI's GPT-5.6 without its approval by David Uzondu Image via @realDonalTrump (X) As OpenAI prepares the release of its next model, GPT 5.6, the White House has instructed the company to limit the distribution of the software to a small group of government-approved partners instead of the general public, as it has done with previous releases. According to The Information, OpenAI Chief Executive Officer Sam Altman sent an internal memo to staff on Thursday explaining that the federal government will approve access "customer by customer" during an initial preview phase. Altman noted in the communication that this restrictive rollout is "not [their] long-term model" for software deployment, and the company plans to work toward a "more sustainable" distribution method later. CNN said that both OpenAI and the Trump administration view the capabilities of GPT 5.6 on the same level as Anthropic's Mythos and that government officials intend to "collaborate with frontier AI labs to develop shared approaches for addressing the challenges of scaling this technology." The latest restriction comes just weeks after the US Commerce Department decided to restrict Fable, a version of Mythos with extra safety "guardrails" to prevent users from exploiting software vulnerabilities. Not long after the release, though, researchers at Amazon found a way to bypass these restrictions, prompting an aggressive response from federal authorities. The government ordered Anthropic to cut off access for non-US citizens located outside the US, non-US citizens living inside the US, and incredibly, even Anthropic's own foreign-born employees. Anthropic now appears to be building a workaround to resolve this compliance block with an update to its Privacy Policy that introduces a category called "Verification Data" to handle KYC and Digital IDs. This setup could mandate digital identity checks to filter users by nationality, requiring a government-issued ID and facial biometric data. Who knows? Maybe in the future, you would have to scan your US Passport or State ID to prove your citizenship before you are allowed to chat with Fable 5 (or any other model).
    • When Windows 7 was released I created an AutoHotkey script that uses Alt+` as a keyboard shortcut to move a window across monitors. I have been using that script for over 15 years and this is the first time I have come across another app that uses the same shortcut!
    • I called it last year that they wouldn't end support when they said there would. There are too many people still on Windows 10 waiting for something better to upgrade to and 11 ain't it! The recent promises of fixing Windows 11's many problems is nice, but unless they deliver on those promises in a big way then I expect customers will still want to stick with 10.
    • Full ACK. I went too far adressing your post specifically. And as you said, it up to us customers as participant of the market dynamic as it happens to decide whether we spend our money on a product or not. The responsibility is to the company. In case of this price hike one could assume that MS is expecting or even starting to see a new interest in XBox hardware so they want to avoid losses per unit sold. I find it fair enough that they granted a period in which everyone interested could grab a unit for the current price (Amazon.de has a reliable stock of XBox Series X digital, which I bought last December after having sold my day one Series X a year ago). It is not that they cash up their customers starting on Monday. Cheers and let's cling to our perfectly fine hardware as long as we deem it worthy in relation to purchasing something new!
