#Update these variables to suit your situation
$OfficeVersion="15.0"
$OfficeApp="Access"
$FileName="My Blocked File.mdb"

#Converts the File Name string to UTF16 Hex
$FileName_UniHex=""
[System.Text.Encoding]::ASCII.GetBytes($FileName.ToLower()) | %{$FileName_UniHex+="{0:X2}00" -f $_}

#Tests to see if the Disabled items registry key exists
$RegKey=(gi "HKCU:\Software\Microsoft\Office\${OfficeVersion}\${OfficeApp}\Resiliency\DisabledItems\")
if($RegKey -eq $NULL){exit}

#Cycles through all the properties and deletes it if it contains the file name.
foreach ($prop in $RegKey.Property) {
   $Val=""
   ($RegKey|gp).$prop | %{$Val+="{0:X2}" -f $_}
   if($Val.Contains($FileName_UniHex)){$RegKey|Remove-ItemProperty -name $prop}
}
