If IE is not set at the default browser, parsing the results `$R.ParsedHtml` after an Invoke-WebRequest results in this pop-up:
![You'll need a new app to open this about]()
If IE <em>is</em> set as the default browser, it's worse. IE opens to a blank page: `about:/UserSettings/ScreenSize`
![IE opens many times]()
It has this same behavior running the script in Powershell Windows 2012R2. Disabling the store only removes the reference to the store, yet the pop-up still appears. With option `-UseBasicParsing` the dialogue box does not appear, however, `-UseBasicParsing` is not an option for the parsing I need to do.
This following solution indicates `onload` within the `<script>` in the parsed html is the problem when the default browser is not IE.

I cannot understand what about `$R.parsedHtml` is causing an open event.
The html body starts with the form action and seems to be the culprit:
<body>
<form action="/UserSettings/ScreenSize" id="screen-size" name="screen-size" method="post">
<input type="hidden" name="width" id="screen-size-width" value="0" />
<input type="hidden" name="height" id="screen-size-height" value="0" />
</form>
Why is it causing a browser to open or the pop-up?
