Windows 10: Shell Infrastructure Host Crashing PC

Good day, everyone.

I have been running into a lot of problems with PC performance and applications crashing lately, and what I've noticed is that there is constant high RAM and CPU usage by these two applications:




These often cause a lot of issues and instability on my computer, causing apps to malfunction, by opening the wrong files, as well as slow down and crash.

Eventually, it gets to a point, where sihost.exe eats up so much of my computer's RAM, that windows completely freezes up and all applications stop working, giving me this error:




This is the highest value of Memory usage that I was able to capture, before my PC crashed:




After the crash, Windows takes around a minute to get all of its services running again, during which certain things, such as the search bar do not work. Subsequently leading to sihost.exe filling up the memory yet again.

The only fix that I've been able to find so far, is restarting the PC, after which Windows becomes usable again. However, this is not the best solution, as it means I have to close down all the apps that I was currently using, and then re-open everything yet again to continue working.


In addition, I have already tried resetting the PC, installing a new, fresh installation of Windows 10 over the old one, but the issue still persists. My last resort is to completely format the disk and then reinstall Windows 10 on it again, before manually carrying over all the backed-up files.


Any help to solve this issue would be greatly appreciated!

Windows defender blocking Shell Infrastructure host

Hi Glenn Taylor (glenn),

Thank you for posting your question in the Microsoft Community.

Shell Infrastructure Host is a core Windows component. Sihost.exe runs the Shell Infrastructure Host. This is critical Windows component and should not be removed. The Windows Shell Infrastructure Host is tasked with handling several
graphical elements of the Operating System interface including taskbar transparency and Start menu.
It’s safe to allow.

I suggest you to follow this article to
Allow a blocked app in Windows Security, and check if that helps.

Regards,

 

Shell infrastructure host has stopped working

I have tried all the methods suggested but still it does not work. Every time I start up my laptop. The screen is just black for about 15 minutes then the dialogue box will appear and says " The shell infrastructure host has stopped working." This happen
since I upgrade my windows from 7 to 10. What will I do to make my computer open fast and to get rid of that shell infrastructure host thing?
