Anyone ever see this?

Anytime I access one of my camera folders that have thousands of meta tagged images in it, Shell Infrastructure Host process starts running like wild and eating up memory like wild. This only seems to happen in folders with TONS of meta tagged files in them, and once it starts doing this, it never really recovers from it, the memory stays used until you reboot, and it constantly eats CPU cycles... everything on MS's forums basically says sfcscan blah blah reinstall windows... nothing useful.... because this happens on a clean install of windows 10 and also windows 11 to me even on first launch.

I'm wondering if this has something to do with windows trying to index the files? Anyone have any experience with this issue?

maybe let it do its thing over night or maybe there is a way of it not scanning for metadata

 

it will just run forever and eventually jam the OS Shell resulting in having to kill it and / or explorer

most of the google results I find point to the windows Photo Viewer of all things being at fault. have you tried removing that to see if there's any difference?

https://www.thewindowsclub.com/shell-infrastructure-host-high-cpu-and-memory-usage seems to have the most details of the results I found. it states the following:

Why does Shell Infrastructure Host use so much Memory?

If Shell Infrastructure Host uses so much Memory on Windows 11/10 PC, you need to uninstall the Photos app and reinstall it from the Microsoft Store. You can then restart the Shell Infrastructure Host process using Task Manager, reinstall Microsoft Redistributable packages, etc. However, if nothing works, run the System Maintenance Troubleshooter.

 

another thought is the pages do state the process is part of what renders GUI objects in the system so that makes me wonder if something is going on with the GPU (or integrated depending on setup) since you mention is happening on a clean install too

    • Using AI to detect security bugs in Windows will now be standard practice at Microsoft

      By sphbecker · Posted

      Sadly, yes. Unless MS brings back some kind of satiety to their QA departments, we will keep seeing generally released patches in a beta state with larger enterprise customers being forced to delay just to avoid issues...which is arguably worse for security than if they patches just came out a little later.

      Here are some off the top of my head. After I made the list, I realized that several of them are more fairly "on the same level as Microsoft," not really worse so I reorganized it. This is all subjective, but I think anyone can give reasons why these companies are hated. Worse that Microsoft: Ticketmaster Flock John Deere Oracle Monsanto Nestle One the same level as Microsoft: Adobe Disney Wells Fargo EA Games Comcast

      And now they are killing Instagram. You have the odd AI post usually but honestly my feed is quite nice. I have a feeling it's about to become crap

    • Anyone can now use your Instagram photos to generate AI images, here's how to opt out

      By Ivan Jenic · Posted

      Anyone can now use your Instagram photos to generate AI images, here's how to opt out by Ivan Jenic Image: Pixabay Earlier this week, Meta launched Muse Image, a new AI image generation feature that lets users create original images, edit existing photos, and even generate custom ads directly within its apps. At first glance, there’s nothing that separates Muse Image from countless other AI image generators available across the board. However, there’s one Muse Image capability that quickly caused controversy. Namely, Muse Image lets users generate AI images using photos pulled from public Instagram accounts. As long as someone's profile is public, another user can tag that account and use their photos as part of an AI-generated creation. Only private accounts and users under 18 are automatically excluded. This feature caused significant backlash, as soon as the broader public learned about it. It’s unclear why Meta even decided to allow this, as if it hasn’t learned anything from Grok’s case from earlier this year, where users were abusing Elon Musk’s AI to generate explicit images of various X users, celebrities, and even underage children. If we can find at least one positive in this, Meta actually gave users a way to opt out of having their Instagram profiles exposed to Muse Image. So, if your Instagram profile is public, and you don’t want virtually everyone to use your photos with Muse Image, you’ll probably want to turn it off. Here’s how to do that: Open Instagram and go to your profile. Tap the three horizontal lines in the top right corner. Scroll down to Sharing and reuse. Find the toggle labeled "Allow people to use your content on Instagram with AI features on Meta." Switch it off for both posts and Reels. If you don’t see this option, make sure to update the Instagram app on your phone to the latest version. The very existence of this feature is a strange fit with Meta’s own recent efforts. The company has been vocal about making its platforms safer to use, especially for children. Having content from millions of users directly available for AI remixing certainly doesn’t fit that blueprint.
