You could retrieve all keys with Get-ChildItem -Recurse and then filter on key names with Where-Object.

The Registry provider is a little different from the FileSystem provider, in that the Name property of each item is the entire key path (ie. HKEY_LOCAL_MACHINE\Software\Microsoft instead of just Microsoft). You can use PSChildName to refer to the leaf name:

if(@(Get-ChildItem HKLM: -Recurse |Where-Object {$_.PSChildName -eq 'RebootRequired'}))
{
  # Something was returned! Create the file
  New-Item C:\Candi\RebootRequired.txt -ItemType File
}

You can suppress error messages from inaccessible keys with the -ErrorAction SilentlyContinue parameter argument with Get-ChildItem
