Disable Dell Display Manager update prompts
Dell releases frequent updates of its Display Manager, a convenient application for making some adjustments on Dell Monitors.
Usually these updates are not important, at least not to all users.
Especially if you are not going to upgrade the program, you really don’t need this constant upgrade prompt.
To disable it, open the registry editor and set the value “LastCheck” to 0 (dword), under the key HKCU\Software\EnTech\DDM
