Hi Mr, Sihost.exe is the Shell Infrastructure Host, which is a Windows System File

Can you get into Command Prompt?

If so, run these commands, one at a time and hit Enter after each one:

sfc /scannow

dism /online /cleanup-image /restorehealth

Hopefully this will repair your Windows System files . . .

ok, i had the same problem like you guys but i found a work around. i manage to keep all my file and program in this way. 

my hypothesis is that the update did not go smoothly due to personal customisation from the user. This causes a problem with the update and thus resulted to boot loop, desktop unavailable ,black screen , sihost.exe and other errors in this recent update. i been digging around this forum and found no solution that might help our situation. So i when to reddit to find a cure and found it. however you might need access to internet connection on another pc and a usb drive with at least 8gb.

i follow a guide by u/brainpitcher and u/juels94

1. Download and prepare a bootable windows media creation tool ver1803 from the windows website
2. Boot into windows and DONT clicking 'ok' to the sihost.exe system warning
3. This somehow enable the explorer.exe to work. Plug the usb in and start the setup.
4. Run the Media Creation Tool (1803) and it will detect updates are available.
5. Follow and run as prompted
6. Wait with patients (Important**)
7. it will then update the windows properly this time.

if you get c:\windows\system.....\desktop error instead, you explorer.exe is likely not working. Press the windows key + R to run the media tool via the run program.

if it fail the first time , try again. it failed on me twice before i get it to work.

i am no expert in windows or anything and my hypothesis is just a guess and nothing more.so dont take my word for it.

**not so much for the process but more for the benefit in life

please be kind to spread this to people that is in our situation if it solve your problem.
