Windows 7 won't update

Question

My problem is that Windows 7 won't update - legal MSDN copy. It says: "the update service is not started", and if I start it, it immediately shuts itself down. In the event viewer is nothing interesting to see, no fatals and no warnings, only start/stop events. I've got no clue from where to start looking, so here's an Hijackthis log:

Answer 2

The following is from Microsoft. The 1st solution fixed my problem:

From the case log, I understand that the error code 80072EFE was received when trying to perform Windows Update. If there has been any misunderstanding, please let me know. I fully understand the inconvenience you have experienced. We will work together to resolve this issue through the course of the case. This issue can be caused by one of the following factors:

1. The computer was attacked by viruses.
2. Some background programs, such as antivirus programs or firewalls (especially CA Firewall), block access to the Windows Update site.
3. Incorrect DNS Settings. We will address some of the more common causes of this issue. It is important that we attempt to connect to the Windows Update web site after each step to confirm whether the resolution has worked. This will prevent us from having to proceed with additional troubleshooting steps and provide us with valuable feedback to further develop our support resolutions for you and our future customers. Your assistance is greatly appreciated.

Suggestion 1: Run the tool to clear spyware

1. Download the file TDSSKiller.zip from the following link and save it on the Desktop.
2. Double click TDSSKiller.zip to unzip the file.
3. Double click TDSSKiller.exe to scan the system.
4. Wait for the scan and disinfection process to complete. Please Note: The third-party product discussed here is manufactured by a company that is independent of Microsoft. We make no warranty, implied or otherwise, regarding this product's performance or reliability.
   Now try Windows Update to see if the issue has been resolved. Please let us know if this step has resolved it. If not, please proceed to the next step.

Suggestion 2: Reset DNS Settings

1. Click "Start", input "NCPA.CPL" (without quotation marks) to Start Search bar and press "Enter".

2. Right-click the network connection and click "Properties". If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

3. Click to highlight "Internet Protocol Version 6 (TCP/IPv6)" and click "Properties".

4. Check "Obtain an IP address automatically" and "Obtain DNS server address automatically".
5. Click "OK".
6. Click to highlight "Internet Protocol Version 4 (TCP/IPv4)" and click "Properties".
7. Check "Obtain an IP address automatically" and "Obtain DNS server address automatically".
8. Click "OK".
9. Reboot the computer. Now try Windows Update again to check if the issue has been resolved. If not, please proceed to the next step.
   Suggestion 3: Disable firewalls or other Internet browser programs that can affect the Internet connection

This issue could be caused by third party applications. Let's first try disabling or uninstalling any third party security applications you may have installed on the computer. Please be advised that this is for troubleshooting purposes only.

Once we have resolved the issue, the applications should be re-enabled or reinstalled immediately. If the third party security application is determined to be the cause, please contact the vendor for assistance. You may have a different security application not listed below that could also be causing the issue. Even if the firewall has been running for some time without any problems, new updates may create issues.

Here is a list of the most common security applications:

• Symantec
• Norton
• McAfee
• Zone Alarm
• Panda Security
• Kaspersky
• Sophos Antivirus
• Comodo Firewall
• AntispamSniper
• Webroot
• Spy Sweeper
• Accelerator
• Spybot

Once the third party security applications have been disabled or removed, please access the Windows Update web site again. If you encounter problems disabling these programs, we recommend completely uninstalling them while troubleshooting.

Before uninstalling any application, please enable your Windows Firewall and ensure that you have the CDs or files needed to re-install the program.

Answer 3

With windows 10, Microsoft has been trying to "bully" other users to upgrade to 10. One form that this has taken has been to given Windows 7 machines low priority on their update servers. And I mean really low priority. Also, some updates seemed to turn off updates for who-knows-why if later updates weren't also done at the same time.

This worked for me...

net stop http /y
net stop wuauserv 
regsvr32 %windir%\system32\wups2.dll 
net start wuauserv 

Then, and this is highly important...

Start windows update, and if it seems to hang...

Let it run for literally 24 hours straight. It literally can take a full day for it to actually get around to downloading updates due to the ridiculoiusly low priority. I can download a Windows 7 SP1 install disk image from a African server using dial-up faster than I can download the updates from 7 to 7SP1 from Microsoft whose corporate campus is literally a 45 minute drive from my house. They're bottlenecking it that much.
