Windows 7: Windows Update stuck checking.

Windows Update stuck checking.

So we have this Acer laptop that, of course, came with all kinds of crap installed that starts up with it.

Getting tired of hearing about how slow the thing is, I disabled a half dozen things (MyWinLocker, LaunchManager, some other crap) that aren't essential, leaving a few things from Intel, MSSE, etc.

Having done that, I restarted it. All was well. Then I opened the Task Manager to kill the GWX process (I hadn't disabled it on that machine yet), and noticed two things:

1. TrustedInstaller.exe would eat a bunch of CPU power, then a large amount of memory, then go back to normal.
2. Immediately following that, one particular instance of svchost.exe starting using 50% of the CPU, and used a massive amount of memory (around 30%), and just stayed there.

So I started looking in to that problem. It shouldn't be sitting there idling at 50% CPU usage, for various reasons. I waited and waited, it would not go away.

One of the possible solutions I found was to disable Microsoft Update. I checked Windows Update settings, and MS Update was indeed enabled, so I disabled that, and also set Windows Update to NOT install anything automatically. The option to re-enable MS Update is now gone.

At this point, Windows Update thought I'd never updated the system, so I clicked "Check for updates" and that's where it sits. Also worth noting, there was a bunch of failed updates from yesterday, including the Upgrade to Windows 10 Home.

For obvious reasons, I'm waiting to decide whether or not I upgrade. That was the plan for that laptop, too, but because Windows Update was set to automatically download AND install stuff, apparently tried to upgrade, and it failed.

Also worth noting, Windows has started telling me that the product is not genuine, via WatUX. I'd actually poked around and found an old thread from these forums about a possible fix for that, which involves rebuilding the Licensing Store. I have not done this yet; I want to fix these other issues first. (However, the system properties show Windows as both activated, and genuine. No idea what's going on here.)

Anyway, does anyone have any suggestions here? I've sat and screwed with this thing for a good 1.5 hours now, and am fixing to send it in to orbit instead.

Edit: I'm also just now seeing the posting instructions for this particular forum. As far as downloading those utilities and collecting logs goes, I'll have to do that and amend my thread later, as the laptop in question is currently in use. I didn't notice any error codes for the failed updates from yesterday, either, as I can only see in the update history that they failed. (And didn't poke around as to why.) But I'm still certainly open to what people think I should do here.

Update:

Posting from the laptop now. Windows Update quit having whatever problem it was having, and displayed found updates again. However, I just noticed they have failed.

Errors:

Code 8E5E0147
Code 8E5E0152

All 6 "Important" updates failed. They consist of one IE11 cumulative update, and five Windows 7 Security Updates.

Edit: Downloading the Windows Update Readiness Tool, and will run it once it's complete, followed by the other instructions in the Instructions thread.

Edit2: The Readiness Tool installed one update, and succeeded. After which, I ran sfc /scannow, which found some corrupted files and could not repair them. Now, normally, I'd be updating this post to include the zipped CBS.log... however, this particular instance of the log, crated today, right after that SFC, is 158MB. That seems... rather unusual, and I'm unsure what to do at this point, as I'm sure that's well beyond the upload limit here.

Meanwhile, the TrustedInstaller/svchost 50% CPU issue is still happening.

The CBS log will compress to around an 8MB zip file using the built-in Windows compression -

Please follow the Windows Update Posting Instructions and post the requested data

If the file is too large (8MB compressed), remove the older CBSPersist cab files until the final file is below the limit - you can always post them separately after zipping them. (the forum doesn't allow the upload of bare CAB files, for a number of reasons)

Please also post the C:\Windows\windowsudpate.log file

(you could also upload the file to a fileshare site and post a link back here.)

I totally forgot I made this thread and I apologize for essentially abandoning it, and for this shameless necro.

However, said laptop is still having issues. I don't know what's wrong with it. The issues it's currently having are:

1. An instance of svchost.exe using 50% of the CPU at all times. When you log on to a user profile, svchost.exe does something, and appears to offload that to TrustedInstaller.exe, which then goes on to use a massive amount of memory, eat the CPU, and then stop. After this, that same instance of svchost.exe starts using a similar amount of memory, while eating 50% of the CPU. If I right-click it and "Go to Service(s)", it points to Windows Update.

2. Windows Update. It either fails to install updates (with 2+ error codes), or gets stuck checking.


In any event, some time tonight I'm going to fiddle with it some more, including uploading the necessary logs to here, if I can. There doesn't seem to be any kind of malware infection or other related problem. MSSE finds nothing, MBAM has found nothing, and I ran both RKill and TDSSKiller on it earlier, both of which came up clean.

If we can't figure out what's wrong with it here, I'm going to just offload any personal data, format it, and reinstall Windows 7 using the OEM disc I have, with the product key on the laptop. (Assuming this will work, anyway. I've read some stories about pre-built PCs/laptops having some kind of "dual key" setup, in which one can quit being valid.)

It was trying to tell me for a bit that the installation of Windows on it wasn't genuine, but I found an old thread on here that you'd posted in, Noel, and it fixed that problem.

Anyway! Again, my apologies. Later, when no one is trying to use the silly thing, I'll go take control of it and see what we can do, if anything.

Bumpity bump.

I'm redownloading SURT right now to run it again; apparently I did something with the original file. However, I ran SFC earlier and it produced a log with a more acceptable size. Still corrupted things it can't fix, of course, but I can at least upload it now without worries. Here is both it and the Windows Update logs.

After the SURT download is finished, I'll run it again, do SFC once more, and see if the log it generates is able to be uploaded here or not.

Bump again, sorry!

SURT ran, found one update (like before), and after a long wait, finally installed it. Here's the CBS log after restarting, after SURT ran.

I need the CheckSUR.log file please.

The new SFC scan shows no unexpected problems - the earlier one fixed a few, leaving only ones associated with well-known update problems, that will be fixed once you get Windows Update working again.

No problems there, either.
KB3074543 appears to be the problem update - since it's an update for .NET 3.5, I would suggest https://support.microsoft.com/en-us/kb/2698555 - and download and run the repair tool.

Greetings! I downloaded the repair tool, and got to the point where it told me to leave the window open and to try updating again... all 11 updates failed once more. Sreenshot attached~
