Hi, honestly i feel quite bad for asking help in my first post here but i can't deal with this problem by myself. So, my Windows Update is not working. Here's my pre-scan:
--------------------------------------------------------------------------------
Scanning Windows Packages Files.

These Files Are Possibly Corrupt (Bad Digital Signature): (Total: 4)
C:\Windows\servicing\Packages\Package_49_for_KB2984972~31bf3856ad364e35~amd64~~6.1.1.4.mum
C:\Windows\servicing\Packages\Package_49_for_KB3003743~31bf3856ad364e35~amd64~~6.1.1.1.mum
C:\Windows\servicing\Packages\Package_50_for_KB3011780~31bf3856ad364e35~amd64~~6.1.1.5.mum
C:\Windows\servicing\Packages\Package_51_for_KB2992611~31bf3856ad364e35~amd64~~6.1.1.0.mum
4 Combined Problems were found with the packages files, these files need to be replaced (These mainly only effect installing Windows Updates.)
The SFC (System File Checker) doesn't scan and replace some of these files, so you may need to replace them manually.
THESE FILES DO NOT KEEP THE REPAIRS FROM WORKING; YOU MAY STILL RUN THE REPAIRS IN THE PROGRAM.
If you need help in replacing these files, post on the Forums at Tweaking.com for help.

there were many more corrupted files (around 40) but i managed to fix them somehow (i ran sfc, sur, chkdsk and renamed software distribution folder but i still have problem installing a number of updates (KB3057154, KB3060716, KB3071756 and a couple of optional updates, it gives me windows update error 80070026) so i thought that maybe replacing these aforementioned files would help. thanks in advance
