Windows could not search for new updates. Error code 8007007E

I've had this problem since 2012.4.25. When i try to run windows update it says "Windows could not search for updates. Error code 8007007E".

I'm using Windows 7 64 bit.

I've already tried fixing the problem from control panel with "fix problems with windows update"

I've also tried Microsoft Fix It program.

I did SFC /SCANNOW procedure and followed instructions in this link http://support.microsoft.com/kb/929833 and there i found in the sfc details that there were some problems with sppc.dll

file. In the file there was often similar texts like below.

Cannot repair member file [l:16{8}]"sppc.dll" of Microsoft-Windows-Security-SPP-Client, Version = 6.1.7601.17514, pA = PROCESSOR_ARCHITECTURE_AMD64 (9), Culture neutral, VersionScope = 1 nonSxS, PublicKeyToken = {l:8 b:31bf3856ad364e35}, Type neutral, TypeName

neutral, PublicKey neutral in the store, file is missing

Could not reproject corrupted file [ml:520{260},l:46{23}]"??C:WindowsSystem32"[l:16{8}]"sppc.dll" source file in store is also corrupted

When i did as the link above instructed and typed "takeown /f C:WindowsSystem32sppc.dll" in the command prompt it said "ERROR: the system cannot find the file specified".
