ODY123 Education has no Start menu/Notification, ie, no Settings for me to get to System > Default apps. I start liking it because it is exactly what I need (if I can manage KMS activation later on). It is OK. Thank you all.
i was find before some reg's but i trough it useless ..but look like the most application based in Reg.key's
IF you have UAC disabled (with registry, if you maybe come from W7 and did a upgrade) then nothing of the new stuff will work. If you have it disabled, just go and renable it. If you don't have it disabled and it doesn't work, well... making a new user account will fix it that too unless there is a bug in the SKU that just breaks it. To set defaults the old Control Panel is still there, so you don't need Settings right now.
try find these path : i think .html or .htm can do the JOB HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts or HKEY_CLASSES_ROOT\.ext or HKEY_LOCAL_MACHINE\Software\Classes\.ext
i have find 1-2 more ...like this Software\Policies\Chromium\DefaultBrowserSettingEnabled or Software\Policies\Google\Chrome\DefaultBrowserSettingEnabled HKLM>POLICIES>GOOGLE>CHROME>DefaultBrowserSettingEnabled=0x00000000 or HKLM>POLICIES>GOOGLE>CHROME>DefaultBrowserSettingEnabled=0x00000001
