When installing Python from the Windows Store, a copy of `python.exe` is installed inder the Microsoft directory in the user's local AppData directory. Currently, `x.ps1` checks for this file, because by default running `python.exe` opens a link to the Microsoft Store rather than running Python. Once the user installs Python, however, this contains a valid interpreter. Unfortuantely, `x.ps1` can't tell the difference between a legitimate Python install and the stub. Remove the check, as it makes it impossible to use the official version from Microsoft once it has been installed. Signed-off-by: Sean Cross <sean@xobs.io>
