November 14, 20223 yr the other day, before starting MSFS I noticed an unusual high CPU load on 1 core, nearly 100% load with no other programs running in the background, or so I thought. the culprit it turned out was a Microsoft service: Shellexperiencehost.exe which supposedly was started by using the Windows built-in photo or image viewer. After killing this not needed service via task manager everything was back to normal. further details: Shell Infrastructure Host has been using about 50% cpu usage and total cpu usage is 100% https://answers.microsoft.com/en-us/windows/forum/all/shell-infrastructure-host-has-been-using-about-50/23617e42-ab06-4984-8a15-3f384379f8f5 How to Fix Shell Infrastructure Host Having High CPU load in Windows https://geekflare.com/fix-shell-infrastructure-host/ I AMD 7800X3D, Windows 11, Gigabyte X670 AORUS Elite AX Motherboard, 64GB DDR5 G.SKILL Trident Z5 NEO RGB (AMD Expo), RTX 4090, Samsung 980 PRO M.2 NVMe SSD 2 TB PCIe 4.0, Samsung 980 PRO M.2 NVMe SSD 1 TB PCIe 4.0, 4K resolution 50" TV @60Hz, VR: Pimax Crystal Light + HP Reverb G2 @ 90 Hz, Honeycomb Bravo Throttle Quadrant, be quiet 1000W PSU, Noctua NH-U12S chromax.black air cooler. 60-130 fps. no CPU overclocking. very nice.
November 14, 20223 yr Never had that problem but I'm also not using the default photo viewer, I use the freeware FastStone Image Viewer.

November 14, 20223 yr Author I mentioned this because I had never seen this before, it was totally unexpected, who would have thought that the Windows default photo viewer could cause such CPU load problems. another popular image viewer that does not exhibit this problem is IrfanView.

I had this problem as well, although I didn't know that Shell Infrastructure Host was the cause. A few days ago I swtiched over to Irfanview as I didn't like Windows 11 photo app and noticed that my CPU load was way lower. I thus purely by coincidence solved the high cpu-load problem 🙂 Kind regards, Hans van WIjhe Acer Predator P03-640 2.10 Ghz Intel 12th Gen Core 17-12700F 64GB memory, Noctua NH-U9S Cooler, 1.02 TB SSD HD, 1.02 TB HD, NVidia Geforce RTX 3070 16GB Memory, Windows 11 (x64)
November 14, 20223 yr The one above doesnt seem to be an issue for me - However I did a windows update a few days ago (right after the su 11 update - man I hate dueling updates for trying to track down issues) and found that afterwards news and interests task was suddenly randomly taking 20 to 30 percent cpu cycles (I have none to spare lol)...I killed via task manager and that seem to help - then I disabled complete from the task bar....such a whack a mole process and never ending......
November 14, 20223 yr Background apps .... all turned off .. Startup apps .. all evaluated and enabled only if it is essential to the running of an essential program. If i start my pc and it doesn't settle down to 1-2% cpu usage at the end of a windows startup sequence i start investigating. Only exception is the occasional running of the system antivirus.

November 14, 20223 yr This does not seem to be an issue for my PC but has come as a timely reminder to run task manager from time to time to check my CPU and memory usage.

November 15, 20223 yr Good find turbo! I use the Win11 default photo app all the time, also whilst running the sim. 7950X3D | RTX 4090 | 64GB DDR5

I use the Win11 default photo app all the time, also whilst running the sim. thanks. it doesn't happen everytime, but when it did, it exhausted 1 core to nearly 100% ! ¿Cómo se dice en inglés increíble? incredible.
