Вернуть Windows Photo Viewer в Windows 10.

После установки Windows 10, стандартным приложением для просмотра графических файлов является... в общем, не тот самый Windows Photo Viewer.

Если вы не используете какой-то нестандартный софт, то пользователи могут быть немного удивлены.

Начать нужно с того, что Windows Photo Viewer нужно "включить" в системе. Для этого нужно проделать небольшие правки в реестре. Сохраните код ниже, как .reg файл:

После импорта .reg файла необходимо добавить ассоциации. В Windows 10 правка реестра для ассоциаций файлов является не очень корректным методом. Работать будет, но регулярно будет сыпать алерты, что ассоциации сброшены/настроены некорректно.

Для выгрузки стандартного полного xml файла ассоциаций можно взять чистую систему, включить на ней через реестр Windows Photo Viewer, возможно, подправить что-то еще и сделать выгрузку файла ассоциаций в xml

Dism.exe /Online /Export-DefaultAppAssociations:C:\defapp-custom.xml

На выходе получаем примерно такое содержимое:

А далее берем SCCM, собираем пакет, кладем в него наш .reg файл, xml файл и, например, .bat (который мы и будем использовать как command line в program у пакета) файл такого содержимого:

 regedit.exe /s %~dp0photoviewer-assoc.reg  
 dism.exe /online /Import-DefaultAppAssociations:"%~dp0defapp-custom.xml"  

Имена файлов, естественно, ставим нужные. Про %~dp0, надеюсь, объяснять не нужно, но гугл, если что, знает.

Добавляем установку нашего пакета в Task Sequence после шага Setup Windows and Configuration Manager, радуемся полученному результату.
