Windows Update svchost high CPU and RAM usage

Howdy all! As the title suggests, I am having issues with windows update.

It started only two weeks ago, when I started up and my CPU monitor said something was running high. After trial and error, I found if I stopped the Windows Updater service, the system went back to normal.

Right now it's taking 13%-20% CPU and 2GB of memory when the updater is active.

I've tried all the suggested fixes from the other threads: reinstalled KB3102810, ran sfc scannow (log attached...but in RAR version, ZIP version was 110MB). I've tried running updates and restoring hidden updates. I can access Windows Update, and it displays one recommended and 2 optional updates to install, but when I try to install those updates, Windows Update just hangs at the downloading updates status (0% downloaded after 24 hours). I ran the SURT, it crashed my system after an hour...ran out of memory...

Suggestions?

Hi radugb & welcome to sevenforums. I'll try to help you.
Have your read & tried Windows Update - Reset?
Have you read this article, from 5 days ago? click here
Try running SFCFix.exe by Niemiro & if it completes, post the log that appears on your desktop.

Thank you for your reply.

I will apply the Windows Update - Reset tonight. I read the article about KB3114717. It does not apply to me since I am running Office 365 with Excel and Word 2016. If the Windows Update - Reset does not work, I will try running the SFCFix.exe.

After several minutes, your CBS.log finally opened. You have numerous entries:

2016-02-14 02:37:38, Info CBS Failed to internally open package. [HRESULT = 0x800f0805 - CBS_E_INVALID_PACKAGE]
2016-02-14 02:37:38, Info CBS Session: 30500627_3109842473 initialized by client WindowsUpdateAgent.

And unrepaired/corrupt files:

2016-02-19 23:03:49, Info CSI 00000541 [SR] Could not reproject corrupted file [ml:520{260},l:46{23}]"\??\C:\Windows\System32"\[l:22{11}]"fontext.dll"; source file in store is also corrupted

failing hard drive? have you run disk check from administrator command prompt? CHKDSK /r

Hopefully, we'll eventually be able to get SURT to complete & produce log.

You can ignore the corrupted fontext.dll message. I modded both it and my shell32.dll files many years back with custom folder icons. I know it shows up as corrupt, but they really are not. Not sure about the "Failed to internally open package". Will the Windows Update-Reset delete all the update packages or do I need to do that manually?

I ran the Windows Update - Reset full patch. No dice, when I go into Windows Update again, TrustedInstaller and svchost both jump to 16% CPU usage and increase in memory until the system memory is full.
