The Windows 10 operating system supports the logging in of multiple users at the same time. Aside from that, it also allows administrators to create a Guest Account that has limited rights. However, there are some instances when you could encounter an error when you use the Guest Account.
The error may state:
“Shell Infrastructure Host has stopped working. A problem caused the program to stop working correctly. Please close the program”.
This error indicates that the Shell Infrastructure Host or SiHost.exe process that is used for handling graphical elements, has crashed. And to fix this error, there are several options you can check out. You can try to reinstall the Microsoft Redistributable Packages or run a System File Checker scan. In addition, you can also use a new Guest Account or troubleshoot the problem in a Clean Boot State.
A corrupted Microsoft Visual C++ Redistributable package or the absence of it can trigger the “Shell Infrastructure Host has stopped working” error – so if you do not have this package yet, you have to install it but if you already have it, follow the steps below to repair it.
After doing all these steps and you still encounter the problem, you might have to uninstall this package and download it directly from Microsoft’s website. However, if you are using Windows 10, you might not be able to do so since it only supports Windows versions up to Windows 8.1 so just proceed to the next option below.
You might want to use a new Guest Account as it could help get rid of the error. All you have to do is have your admin delete the old Guest Account and create a new one and see if it helps in fixing the error.
Setting your computer in a Clean Boot State can help you diagnose and later troubleshoot the problems in your computer. During this state, the system will start with a minimal number of drivers and startup programs that help in isolating the problem with the interfering software. To put your computer in a Clean Boot State, follow the given steps below.

Many device drivers are already built into the operating system. But sometimes you will need to install a new device driver when you want to use a new piece of hardware device that the operating system is not familiar with, or does not anticipate.
Regardless of whether or not the drivers are already integrated into the operating system, you may still experience code 39, typically because of the corrupted or outdated drivers.
