When installing march tuesday updates I got windows update error 57A when installigng KB2837594.
Events viewer show the following event for MSinstaller
Product: Microsoft Filter Pack 2.0 -- Error 1402. Could not open key: UNKNOWN\Components\8C74AF50DE82925438E3210E61AC7181\00004159000290400100000000F01FEC. System error 5. Verify that you have sufficient access to that key, or contact your support personnel.
In fact, there are several keys in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Components which have a subkey \00004159000290400100000000F01FEC that cannot be accessed.
I manually restored access to all of them and Windows update was able to proceed normally.
I have a similar issue installing Exchange 2013 CU2 with subkey \AE1D439464EB1B8488741FFA028E291C
My problem is that manually resetting keys permission is alsmost impossible because of the number of keys involved with exchange.
Is there a way to reset ownership and permission of these keys using Powershell ?
