So, I tried updating windows (Windows 7 Home Premium SP1 64 bit) for the first time in about a month. It always worked fine before, but now, not so much. Windows Update tends to just sit at 0% for an extreme period of time. The one time I left the computer running for a few hours, it finished the updates, but then I got a BSOD error c000021a and spent all day fixing that. I ran SFC /SCANNOW and it found "corruption" that it was "unable to fix". The .log file was unopenable, but I found a command to pull the relevant text out into a txt document. Well, the txt file was useless, not a single problem listed. Then I found out about SFCfix and ran it. It found 2 corruptions apparently, but didn't fix them. Log:

Well I'm running out of ideas. As long as I don't have to reinstall or break everything with another windows update run, I'll try anything. As for posting with a zip of the CBS folder... it's too big to put in this post. The logfiles will follow shortly.
 
Hi paragonofevil :)

My name is Aura and I'll be assisting you with your issue. Since the .zip file that has been uploaded is corrupt, I'll need you to provide me new logs. Follow the instructions below please.

System Update Readiness Tool (SURT) - Scan
Follow the instructions below to run a scan with the System Update Readiness Tool (SURT) and provide a log;
  • Download the right version of SURT for your system;
    • Your version of Windows is: Windows 7 SP1 x64
  • Once downloaded, execute the installer, and go throught the installation (this process can take around 15-20 minutes);
  • On completion, a log will be created in C:\Windows\Logs\CBS\CheckSUR.log;
  • Attach this log in your next reply;
Alternatively, if these instructions are unclear for you, you can follow the tutorial below.

System Update Readiness Tool (SURT)
 
That SURT link only seems to work if I chop the ?wa=wsignin1.0 off the end. Anyways here's the log file, there's also a CheckSUR.persist.log in there, a CBS.log, and a DeepClean.log

Alright, SURT returned a clean CheckSUR.log. Let's see if it's the same with SFC and the CBS.log.

System File Checker (SFC)
Follow the instructions below to run a SFC scan on your system and to provide the CBS log in your next reply;
  • On Windows Vista & 7, click on the Windows Start Menu, then enter cmd in the search box, right-click on the cmd icon and select
    Spcusrh.png
    Run as Administrator
  • On Windows 8, drag your cursor in the bottom-left corner, and right-click on the metro menu preview, then select Command Prompt (Admin);
  • On Windows 8.1, right click on the Windows logo in the bottom-left corner and select Command Prompt (Admin);
  • Enter the command below and press on Enter;
    Code: 
    sfc /scannow
    Note: There's a space between "sfc" and "/scannow";
  • Once the scan is complete, enter the command below and press on Enter
    Code: 
    copy %windir%\logs\cbs\cbs.log "%userprofile%\Desktop\cbs.txt"
  • A file called cbs.txt will have appeared on your Desktop. Upload the file on Dropbox, Google Drive or OneDrive and post the download URL for it here;
Note: Please note that the CBS.log is volatile, which means that if you don't upload it after the SFC scan is completed, it won't have the information from the scan anymore. So archive it and upload it as soon as you can.
 
Alright, SFC also returned a clean CBS.log. Follow the instructions below please.

Alright. Now, try to download and install your Windows Updates. If they fail, upload the two files below for me to review.

C:\Windows\WindowsUpdate.log
C:\Windows\Logs\CBS\CBS.log
 
A brief update while that's going on; my Tune Up Utilities program shows a computer error: "Windows reports that the "QWAVE driver" device is not working properly." I have no idea what that means. Only TuneUp has picked this up, I'm not getting errors anywhere else or noticing any problems.

The update this time isn't sitting at 0%, it's showing progress. I'll update after rebooting.
 
I would advice you to uninstall AVG PC TuneUp.

"PC Booster/Tune Up" programs are part of the worst programs you can install on a system. When it comes to messing up your system (Windows), these are as worst as malware. They are completely worthless and useless to use. The worst is that they'll often take action on your system without you knowing, nor authorizing it, which could lead to your system being altered in a way you don't want it to be or even worst, a "broke" system. Every feature they provide, you can either do it natively under Windows, do it via another standalone executable (which is way easier and safer to use) or they aren't providing something you need. Here's a few examples:
  • Cleaning temporary files: TFC (standalone executable), CCleaner (installed), Cleanmgr.exe (built-in);
  • Managing start-up entries: Autoruns (standalone executable), CCleaner (installed), Task Manager and Registry Editor (built-in);
  • Driver Updater: Not needed, all you need is to go on your manufacturer website so you'll be sure to get the right, official, working drivers for your computer or hardware;
  • Registry Cleaner/Defragger: Completely useless and also dangerous;
  • Disk Defragging: Disk Defrag (built-in), O&O Disk Defrag (installed), Defraggler (installed);
  • Powerful uninstaller: Not needed, only needed when you have to make sure a program is completely uninstalled. Revo Uninstaller and GeekUninstaller are two good alternatives;
  • "Enhanced" Task Manager: ProcExp from Sysinternals Suite (standalone executable), Process Hacker (portable or installed);
  • "Active security": Any Antivirus and Antimalware can beat that, easily. These programs aren't made to replace Antivirus or Antimalware products and shouldn't be seen as such;
  • Repair bad sectors on a hard drive: Simple chkdsk /r command under Windows (built-in);
Having such program installing on your system will just bloat it down and you have more chances to have issues by using them than without. These products are advertised as a program that can solve all your issues, remove every malware, speed up your computer performance over 100%, etc. The truth is that there's not a single program that can do that. First of all, these programs aren't made to remove virus and malware, leave this in the hands of Antivirus and Antimalware, period. Secondly, there's so many kind of issues under Windows that there's not a single program that can address them all. If you think that BSOD (Blue Screen of Death) issues can be solved by opening a program and clicking on a "Fix" button, then I'm sorry to tell you but, you're wrong. Also, you cannot boost the performance of a hardware over it's hardware capabilities. Of course you can overclock some components, like your CPU, RAM and GPU, but these aren't done via these programs, but via your BIOS interface. I could recommend you a program for every feature these programs advertise, and also tell you exactly in detail why most of them are completely useless, such as Registry cleaner (dangerous to use), and driver updater (dangerous to use, and also completely useless, it'll not improve your system performance). In the end, buying such programs is the exact same as being scammed (because this is what it is, a pure scam) and using one of these programs will result you in having a system less performant than prior to using it.

Relevant articles if you want to read more about PC Boosters/Optimizers and why they are useless:
 
Well, bad news. Everything looked fine, until my system rebooted, got to the Starting Windows screen, and then a BSOD popped up causing it to get stuck in a cycle of reboot and BSOD without getting back into windows. (The BSOD is the same as last time, c000021a Fatal Error) This is the second time that's happened now. I fixed it this time same as I did last time: popping in the win 7 disk, trying to use it to repair the system (it doesn't know how), and then using it to open a command prompt and this command:
dism /image:C:\ /cleanup-image /revertpendingactions
After that I rebooted, windows failed all but one update (a Microsoft security essentials update), and here we are.

As for AVG, I'll uninstall it once windows is working properly again. It still tells me I have the "QWAVE driver" error.

Here's WindowsUpdate.log: WindowsUpdate.log - Google Drive

I'll attach CBS.log in my next post, it's huge so I'll link it once drive uploads it.
 
One of the update could be causing the BSOD bootloop. Can you list me the KBs you are trying to install?
 
I uninstalled AVG. Here's the updates that haven't installed:
Cumulative Security Update for Internet Explorer 11 for Windows 7 for x64-based Systems KB3160005
Security Update for Windows 7 for x64-based Systems KB3159398
Security Update for Windows 7 for x64-based Systems KB3161561
Security Update for Windows 7 for x64-based Systems KB3161664
Security Update for Windows 7 for x64-based Systems KB3161949
Security Update for Windows 7 for x64-based Systems KB3161958
Security Update for Windows 7 for x64-based Systems KB3164033
Security Update for Windows 7 for x64-based Systems KB3164035
Update for Windows 7 for x64-based Systems KB3162835
also an optional update
Update for Windows 7 for x64-based Systems KB3161608

There were others like KB3035583 but I hate the win10 annoyware so I have them hidden
 
Alright. Now, please install each one of your available updates one by one. This way, if one triggers the bootloop, we'll be able to identify it and deal with it separately.
 
So far I've got KB3161561 to install fine, but then I tried to install KB3161664... I had to reboot the computer and restart the windows update service to get it to get past "Searching for updates on this computer", then it installed unusually fast, rebooted, BSOD. I don't know if it was the updater being weird or that particular KB but I'll install the others meanwhile and see what happens.
 
OK. I installed, one by one, every update, even a Silverlight update. All of them took, except aforementioned KB3161664. I installed it three times, and each time caused the BSOD cycle. None of the others had any problem. Interesting.
