Not currently. You're welcome to send PR with uninstall.reg file, that will remove the keys being added during install.

Just create uninstall.reg file and in this file you can type

REGEDIT4
[-HKEY_CLASSES_ROOT\phpstorm]

It will remove the registry entry created by run_editor.reg

1. adds uninstall.reg file
2. updates instructions in the README.md explaining the uninstall workflow
