After installing Python from Microsoft Store, this fails:

```
>>> open('C:\\Users\\Kagami\\AppData\\Local\\Microsoft\\WindowsApps\\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\\python.exe')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OSError: [Errno 22] Invalid argument: 'C:\\Users\\Kagami\\AppData\\Local\\Microsoft\\WindowsApps\\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\\python.exe'
```

This causes virtualenv to fail on it:
