[New-bugs-announce] [issue28011] winreg KEY_READ also fails for some keys

New submission from Pabitra:

UAC does not give KEY_ALL_ACCESS on various keys, that's a know fact. But, KEY_READ access also throws WindowsError: [Error 5] Access is denied for few keys.

Out of all the keys in HKEY_USERS, I am trying to access, "S-1-5-18",  "S-1-5-19" and  "S-1-5-20". Openkey() with KEY_READ works fine for "S-1-5-18". However for "S-1-5-19" and  "S-1-5-20" it fails (even if I use KEY_READ access).

Then how can I read the values for those specific keys, if KEY_READ also shows access denied?
