## TL;DR

I don't know why but the first letter of the property you want to set must be lowercase e. g. physicalPath This will work: set-itemproperty myapp -name physicalPath -value D:\Projects\Demo Seems like a bug to me but this notation (first letter lowercase) also works for your other Windows environments thus should be a valid workaround.

## Steps

1. I don't know why but the first letter of the property you want to set must be lowercase e. g. physicalPath This will work: set-itemproperty myapp -name physicalPath -value D:\Projects\Demo Seems like a bug to me but this notation (first letter lowercase) also works for your other Windows environments thus should be a valid workaround.

## When to use

You are seeing this: Works absolutely fine on Windows 7, Windows 8.1, and on all our Win2012 production servers. Use this skill when you run into "Why does Set-ItemProperty have no effect for IIS applications under Windows 10?".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
