Как отключить dvr ничего не помогает

After you change the value in the registry, you should try modifying the permissions on the registry key so that so that no one has the rights to change the key. The steps below need to be applied to both of these keys: HKU\S-1-5-21-3381321717-982676326-1647861846-1001\SOFTWARE\Microsoft\Windows\CurrentVersion\GameDVR\ HKU\S-1-5-21-3381321717-982676326-1647861846-1001\System\GameConfigStore\

Open Regedit, and navigate to the key
Make your changes
Right-click on the key on the left (the folder) and select permissions.
For each user in the list, click them and if Full Control under the Allow column is checked, uncheck it, leaving only Read under Allow checked.
That may be enough to prevent future changes, but if the system decides to change the permissions back then you would still have the problem. If it still happens after trying the above, you might try taking ownership of the key and explicitly denying Write access to the key for SYSTEM and your user.

Right-click on the key on the left (the folder) and select permissions.
Click Advanced
The Owner is probably SYSTEM. Click change, and set it to your user account instead.
After you've done that, click OK till the Permissions window is dismissed and reopen it so that the change you just made takes effect.
Click Advanced again.
Click "Disable inheritance" and in the dialog that pops up, click "Convert inherited permissions..."
You should see a list of users and their access. For each user that has an access of Full Control, double-click the user account to open it and uncheck Full Control, leaving only Read selected.
Click ok on all the open dialogs and close regedit

RockInHeart, я плохо понимаю что написано, с переводчиком что то тоже не ясно. И в реестре у меня такого вроде нет

Не могли бы, более подробный мануал сделать по удалению "Системы" из доступа?

Тоже не отключается

А вот интересно - у вас, случайно, в папке C:\WINDOWS\system32\config файла software.sav нету?

есть что то похожее:

Подожду гайд от RockInHeart.

Win+R - gpedit.msc и отключить параметр тот что указан на скриншоте

RockInHeart, пробовал, у меня такого нет на Windows 10 Enterprise LTSB
