Portable App Development

What do I use in my launcher .ini file if I want to discard a registry setting (in HKCU) that has changed whilst the app is in use and therefore revert back to the original setting?

Thanks

Are there any icon sets available for use while a project is in development?

I know, old topic. But relevant and times do change. Where is a good place to host a portable app for download when the app isn't open source. This one is freeware.

So what would the current thinking be on a Python Portable app. Should placement of the python language folder be in X:\PortableApps\PythonPortable? Or into the CommonFiles folder, ie. X:\PortableApps\CommonFiles\python?

I almost choked on my own spittle trying to navigate this site in the hopes of converting an already stand-alone app into a paf.exe. The first challenge is that the starting point isn't so clear.

Is there a true need for a Portable Utility to download and install the Java JDK? I know I wish there had been when I was looking to no avail. Did find a Powershell script that did the trick with a little tweaking.

I initiated porting muCommander to PortableApps (https://portableapps.com/node/51352) but I don't have an expertise to further the project. It is a Java application universal to all OS. Currently, UTF-8 support in file name is not working properly, and FTP and WEBDAV support has not been tested. Althought the development has been suspended for a long time its rich set of optons is still very comparative and competitive.
