Windows Script Host is a runtime engine for several script programming languages.
Wikipedia says there following here:
"Windows Script Host is distributed and installed by default on Windows 98 and later versions of Windows. It is also installed if Internet Explorer 5 (or a later version) is installed."
The same article explains here, which versions of Windows contain which version of WSH.
If you do not have WSH installed, then your Windows installation is incomplete. Perhaps it is not a full retail version. To check more thoroughly, open a command line window and enter the command: cscript
If WSH is installed, it should answer. The first line contains its version number.
You can download WSH 5.7 here and install it on your computer. But you may not need WSH with any urgency. The bigger question may be, if WSH is missing, what else is also missing and why is WSH missing?
Possible reason WSH is missing

I found that some registry cleaner programs can delete your WSH. I think that might have been my problem. I have used RegSeeker a few times and while I try to be careful what I delete the lists are way too long to go through completely.
I tried to run sfc /scannow to recover the missing files but then Windows kept freezing during reboot.
Luckily a rollback to its last working state fixed that, and since everything is working good right now I'm gonna leave things as they are.

It seems a bit strange that a registry cleaner would not only delete registry entries, but also delete files. However, these days nothing is impossible. Quality software is rare.
