What is ShellExperienceHost.exe?

Windows Shell Experience Host is a genuine Windows process that provides the functionality to display universal apps in a windowed interface. Essentially, what this process does is handle several graphical elements of the application’s interface: taskbar and start menu transparency, calendar, clock, background behavior, notifications visuals etc.

When the Windows Shell Experience Host was first introduced with Windows 10, the very first versions were buggy and consumed a lot of CPU and RAM. However, with the latest updates, the functionality of this process has drastically improved.

The normal behavior of shellexperiencehost.exe is to consume little to no CPU resources. However, if you monitor it closely you should be able to see occasional CPU spikes when new graphical elements are changed, but then consumption should revert back to zero. The memory consumption should not exceed 300 MB even if you have a lot of applications that are using Windows Shell Experience Host.

Potential security threat?

As it turns out, the Trojan family that is known to camouflage as the shellexperiencehost.exe process is used to mine for the Monero digital currency.

If you suspect that you might be dealing with a trojan, it’s location will be a major giveaway.

If the revealed location is in C:\ Windows \ SystemApps \ ShellExperienceHost_cw5n1h2txyewy, you can rest assured as the executable is not malicious.

If the executable is in a different location and you noticed constant high resources consumption, there’s a high chance that you’re dealing with a trojan that is mining cryptocurrencies.
