Question: I am hosting a Wordpress website in `IIS 8`
I am getting the following error:

> 
> Failed to load resource: the server responded with a status of 500
>  (URL Rewrite Module Error.)
> 
> 
> 

When I upload a new image and display.
If I go to `wp-content` and give `IIS_USRS` access then the image works, when I add a new image I have to remove `IIS_USRS` and add it again for the image to work

If I use the following web config the website never loads

```
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
  <rules>
    <rule name="wordpress" patternSyntax="Wildcard">
      <match url="*" />
        <conditions>
          <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
          <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
        </conditions>
      <action type="Rewrite" url="index.php" />
    </rule>
  </rules>
</rewrite>

```

Answer: 
I changed the permissions in the security tab to the wp-content folder of wordpress within the iis manager, it was necessary to edit and then I gave full control to IIS\_USRS and the error was solved
For me, changing the identity of the app pool worked(thx lockstock).
As a workaround, I tested it by cropping the images and saving them, there was no need to edit the permissions.
I use win server2019 with the latest updates (IIS 10 and PHP 7.4).

NOTE:
If you are creating a new wp site, by default use http://localhost/?P=123 as permalinks, but if you want to change this to %postname%, wp creates a new roule under URL rewrite on IIS, this is the reason for displaying the error for any file, post.
I hope it's helpful.
