By default, Adobe Acrobat Reader DC is set to automatically download and install updates, and the ability to disable or configure automatic updates has been removed. But you can still configure/disable this through the registry in the following key:
Replace product name and product version accordingly. For example: Reader\{AC76BA86-7AD7-1043-7B44-AC0F074E4100}
Under the key, set the Mode DWORD value to one of the following:
| 0: | Do not download or install updates automatically. |
| 1: | Do not download or install updates automatically. |
| 2: | Automatically download updates but let the user choose when to install them. |
| 3: | Automatically download and install updates. |
| 4: | Notify the user downloads are available but do not download them. |
