Unable to enable/install WSL on Windows 10 Pro ver. 1803

[Jimbazuka]

Windows build number: ver shows "Microsoft Windows [Version 10.0.17134.228]"
winver shows: windows 10 Version 1803 (OS Build 17134.228)

Description & Steps to Reproduce
I am trying to enable WSL (Windows Subsystem for Linux) and each time, regardless of how I do it,
it ends with failed to update and undoing changes, usually after 2 reboots.
so far I tried the:

1. Checkbox from Turn Windows Features On or Off and checking the "Windows Subsystem for Linux" (with and without turning on the developer mode)

2. The power-shell method i.e. opened power shell as Admin and typed:
   Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

3. The Dism method i.e. from cmd prompt: dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux

After reboot, all methods end up the same: with same failure:
We couldn't complete the features
Undoing changes

Logs (all log files are attached)
regarding the 3d (Dism) method, I examined the dism.log (C:\Windows\Logs\DISM) and I note the following lines:

2018-08-28 15:34:09, Warning DISM DISM OS Provider: PID=8244 TID=1472 Unable to set the DLL search path to the servicing stack folder. C:\Windows may not point to a valid Windows folder. - CDISMOSServiceManager::Final_OnConnect

also 2 info consecutive lines:

note the latter refers to it as:
Encountered an unknown option "featurename" with value "Microsoft-Windows-Subsystem-Linux"

However, no apparent errors (or reason for failure) were logged here.

Finally, windows log setup showed an event:

Update Microsoft-Windows-Subsystem-Linux of package Microsoft-Windows-Lxss-Optional failed to be turned on. Status: 0x800f0922.

WSL works fine for me on Windows 10 Version 1809.

This looks similar to #3063 and #931. Looking through your CBS.log file it seems the WSL install is being blocked by some network driver.

Thank you benhillis ! I had the ZoneAlarm free firewall install, a checkpoint product. As far as I know it does not have any VPN but as a precaution I uninstalled it, then turn the WSL feature on and it installed with no issue.....
