Sihost.exe unknown hard error since latest Windows 10 update

Question

Hello everyone, since the latest update on Windows 10 (may 2018), I'm unable to enter on my profile on my computer. Whenever I try to start it, shows the following error message "sihost.exe unknown hard error", then if I continue and log into my profile, comes out the next error mesage: "location not available, can't obtain acess to C:\WINDOWS\system32\config\systemprofile\Desktop. Acess denied" with the screen behind it completely black, can't acess the start menu, internet or settings, and the only icon in the desktop it's the recicle bin. It's there a way to troubleshoot this? Or why is this happening? Any solutions? Or even someone who has the same issue. Thank you for your answers :D

Answer 1

This happened to tons of people. I am great at fixing my computer. I spent 10 hours and still have the issue. You will have to download a 3rd party fix for about $20-30. Microsoft will not help you. You can find a fix to get your desktop back on google, but will still have problems with the startup. Next time make sure you make a system mirror, system backup and restore...maybe that may save the $. Or Pay $100 for the Windows Disk, or get a Macintosh

Answer 2

I have tried this and it will not do the required tests. I says they are unavailable. There is no windows start menu or any way to do and Admin either. I cannot even request the Update to download.. I have to pay for a 3rd party software fix

Answer 3

there are some software offered problem solving, but i don't know which one is proven, i am finishing final project on my laptop, so reinstall windows is almost imposible. If there any of you already tried a software and it's work, please share. i don't want to waste my money and time trying some software out there.

thanks bryan, i really appreciate it

Answer 4
