Инсульт, наблюдается ли проблема под другой учетной записью?

Покажите содержимое разделов реестра:

• HKEY_CLASSES_ROOT\.avi
• HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.avi\UserChoice

и разрешения на них (правой кнопкой мыши -> Разрешения -> кнопка Дополнительно).

[Инсульт]

Учетная запись одна. Но скорей всего проблема в пределах юзера. Появилось скорей всего после удаления windows media player через "компоненты windows" Что интересно удаление плеера на х86 таких проблем не вызывало.

.avi

[HKEY_CLASSES_ROOT\.avi]
@="mplayerc.avi"
"PerceivedType"="video"
"Content Type"="video/avi"

[HKEY_CLASSES_ROOT\.avi\OpenWithList]

[HKEY_CLASSES_ROOT\.avi\OpenWithList\ehshell.exe]

[HKEY_CLASSES_ROOT\.avi\OpenWithProgIds]
"WMP11.AssocFile.AVI"=hex(0):

[HKEY_CLASSES_ROOT\.avi\PersistentHandler]
@="{098f2470-bae0-11cd-b579-08002b30bfeb}"

[HKEY_CLASSES_ROOT\.avi\ShellEx]

[HKEY_CLASSES_ROOT\.avi\ShellEx\{BB2E617C-0920-11D1-9A0B-00C04FC2D6C1}]
@="{9DBD2C50-62AD-11D0-B806-00C04FD706EC}"

[HKEY_CLASSES_ROOT\.avi\ShellEx\{e357fccd-a995-4576-b01f-234630154e96}]
@="{9DBD2C50-62AD-11D0-B806-00C04FD706EC}"

А вот в HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.avi\UserChoice зайти не разрешает. "отказано в доступе" как и во всех записях этой ветки \FileExts\ точнее только видео\аудио файлов. Просмотр разрешений так же недоступен "У вас нет разрешения на просмотр текущих параметров, но вы можете изменить разрешения"

Просмотр разрешений так же недоступен

Нажмите кнопку Дополнительно и перейдите на вкладку Владелец.

Менять владельца тоже не давало по отельности на раздел. Поменял владельца сразу на \FileExts\ та же выставил им юзера т.к у всех расширений юзеров не было. Не знаю правильно так или нет но в данный момент работает и так.
