Disable Adobe Reader Updates

If you need to disable Adobe Reader from automatically updating or asking to be updated on Windows you can do so by creating a REG_DWORD registry key named bUpdater.

Here is the location to create the key;
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Acrobat Reader\10.0\FeatureLockDown

Notice the \10.0\ in the above address.   Replace this with the version you are trying to configure.
Inside the above address create this key;
REG_DWORD   bUpdater   0x00000000

Setting this value will disable the updater and remove the "Check for updates" option in the help menu.

Here is the reference from Adobe's website.

I used the following PowerShell script to search for all FeatureLockDown keys and disable the Updater regardless of the version of Adobe Reader that is installed.

"Disabling Adobe Acrobat Reader Updates."
$featureLockDownKeys = Get-ChildItem -Path HKLM:/SOFTWARE/Policies/Adobe -Recurse | Where-Object -Property Name -Match "FeatureLockDown$"

foreach ($fldk in $featureLockDownKeys)
{
New-ItemProperty -Path $fldk.PSPath -Name "bUpdater" -Value 0 -PropertyType DWORD -ErrorAction SilentlyContinue | Out-Null
New-ItemProperty -Path $fldk.PSPath -Name "iDisablePromptForUpgrade" -Value 0 -PropertyType DWORD -ErrorAction SilentlyContinue | Out-Null
}
