I have had SQL Server 2012 intsalled and running fine on my Windows 10 laptop.
However, following a failed windows update, which also wiped out my restore points!, I had to 'reset' windows 10 and since then I have not been able to succesfully install SQL Server.
I believe that the following is the problem:-
(01) 2016-09-30 17:54:49 Slp: The following is an exception stack listing the exceptions in outermost to innermost order

I have looked at the registry and HKEY_LOCAL_MACHINE@SYSTEM\CurrentControlSet\Services\FltMgr is owned by system and I cannot change that ownership.
Any help or advice will be greatfully recieved.
