Question

I have the problem described in #10766, but I had activated ISS only for curiosity, and since then, even after deactivating it (I don't need it), youtube-dl binaries on my PC fail with this error:
C:\Users\piez>youtube-dl -v [debug] System config: [] [debug] User config: [] [debug] Custom config: [] [debug] Command-line args: ['-v'] Traceback (most recent call last): File "__main__.py", line 19, in <module> File "C:\Users\dst\AppData\Roaming\Build archive\youtube-dl\ytdl-org\tmp378onz6j\build\youtube_dl\__init__.py", line 474, in main File "C:\Users\dst\AppData\Roaming\Build archive\youtube-dl\ytdl-org\tmp378onz6j\build\youtube_dl\__init__.py", line 441, in _real_main File "C:\Users\dst\AppData\Roaming\Build archive\youtube-dl\ytdl-org\tmp378onz6j\build\youtube_dl\YoutubeDL.py", line 419, in __init__ File "C:\Users\dst\AppData\Roaming\Build archive\youtube-dl\ytdl-org\tmp378onz6j\build\youtube_dl\YoutubeDL.py", line 2345, in _setup_opener File "C:\Users\dst\AppData\Roaming\Build archive\youtube-dl\ytdl-org\tmp378onz6j\build\youtube_dl\utils.py", line 2288, in make_HTTPS_handler File "C:\Python\Python34\lib\ssl.py", line 439, in create_default_context File "C:\Python\Python34\lib\ssl.py", line 390, in load_default_certs File "C:\Python\Python34\lib\ssl.py", line 377, in _load_windows_store_certs PermissionError: [WinError 5] Accesso negato
(unless I have administrative privileges). I need to use the youtube-dl exe version for compability with MPC-HC (clsid2/mpc-hc#301), what I have to do to make youtube-dl work again?

But before it worked, and ISS now is deactivated. What has changed in my system?
