Я проверил, мой код открывает 64-битный реестр, Python 64-битный, система 64-битная. Я попытался снова открыть проводник Windows, закрыть и снова открыть реестр и перезапустить систему. Ничего не изменилось.
Для настроек, в которых я создал значение и установил для него атрибут «данные», он сохраняется между сеансами, и я могу проверить его в своем коде, как если бы он его хранил. ГДЕ-ТО.
Это код:

- DisallowShaking был НЕ создано
- HideFileExt НЕ было установлено в 1
[img]https:/ /i.sstatic.net/Qhhk8DnZ.png[/img] - key Software\Classes\CLSID\{86ca1aa0-34aa-4e8b-a509 -50c905bae2a2}\InprocServer32 НЕ создан
- ключ SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Blocked НЕ создан
- значение {e2bf9676-5f8f-435c-97eb-11607a5bedf7 явно не существует, но выводится так, как если бы оно существовало.
