Following a clean install, Windows Update remains at "Checking For Updates" forever...

I've reloaded hundreds of Windows computers over the years and I like to think that I am reasonably proficient at that process.  I have just encountered an issue that required a lot of time and effort to resolve and I am posting this to try and save someone else the same ordeal.

My customer had a late model, name-brand Windows 7/64 SP1 computer with a disk drive that was failing.  I changed out the disk drive with a replacement and went through the recovery process, using the manufacturer-provided Recovery Media.  That media is supposed to be identical to the image loaded on the drive from the factory - Windows 7/64 with SP1.

Following the reload, I followed my normal procedure and launched Windows Update.  Windows Update remained at "Checking for Updates" for hours, without ever displaying any updates to install.  I restarted the PC and tried again, with exactly the same result.  The Software Distribution folder would get built and there were plenty of entries in WindowsUpdate.log, but eventually disk activity would cease but CPU activity would remain over 50%.  And Windows Update just showed "Checking for Updates" forever.

I decided the reload must have been bad and so I repeated it from scratch again with exactly the same result.  At that point I decided the image on the manufacturer's Recovery Media must be defective and so I reloaded from my MS Partner Program Windows 7/64 SP1 DVD.  I had the same exact symptoms and result again.  I thought that maybe I was not waiting long enough, so I left it running overnight.  The next morning, it was still at "Checking for Updates".

I tried additional reloads using SURT and that also remained at "Checking for Updates" without accomplishing anything.  I tried using the Windows Update Troubleshooter - with no luck.  Ditto for manually resetting Windows Update and various combinations of these techniques.  I verified that Windows was activated and that date/time were correctly set.  Nothing made any difference.

I then started meticulously documenting everything as I went along and I think I've found a solution:

After the reload, I checked the Windows Update components in C:\Windows\System32. The components are wuapi.dll, wuapp.exe, wuaclt.exe and wuaeng.dll and all are version 7.5.7601.17514 dated 11/20/2010.  Once you launched Windows update or run SURT, these are all updated directly to version 7.6.7600.320.  At that point, I get the symptoms described above and there doesn't appear to be any way to recover.

When Windows Update is launched, it first updates itself automatically and without the user having any option.  It appears that upgrading the WU components from7.5.7601.17514 directly to 7.6.7600.320 causes the issue.  I suspect that it works fine for computers that are updated incrementally.

Once WU version 7.6.7600.320 is loaded, there is no easy recovery that I could find.

CURRENT PROCEDURE:


  1. Download https://support.microsoft.com/en-us/kb/3020369 and https://support.microsoft.com/en-us/kb/3172605 in advance.
  2. Disconnect the computer from the Internet so Windows Update cannot automatically update itself to 7.6.7600.320.
  3. Perform a fresh reload from Recovery Media or Windows 7/64 with SP1 RTM.
  4. When the installation prompts for updates, choose "Ask Me Later".
  5. Apply KB3020369 and then KB3172605 in that order.
  6. Restore the Internet connection, configure update settings to your preference and launch Windows Update as normal.

ORIGINAL PROCEDURE FROM JANUARY 19 2016 HAS BEEN DEPRECATED BY THE NEW PROCEDURE ABOVE:


  1. Download KB3083710 and KB3102810 in advance.
  2. Disconnect the computer from the Internet so Windows Update cannot automatically update itself to 7.6.7600.320.
  3. Perform a fresh reload from Recovery Media or Windows 7/64 with SP1 RTM.
  4. Manually install KB3083710 and restart - WU components will now be version 7.6.7601.19016 dated 9/25/2015.
  5. Manually install KB3102810 and restart - WU components will now be version 7.6.7601.19046 dated 10/20/2015.
  6. Restore the Internet connection and launch Windows Update as normal.
  7. After a few minutes, you should have plenty of updates to download and install.

    Hi again CT,

    My wife uses the same technique as you for passwords.  I just hope she doesn't lose the piece of paper they're written on, or have it stolen in a break in.  I have mine saved because I use several of them several times a day rather than stay logged in.  As I said earlier, I'll look at the reports you've linked to.  I'm warming to the idea already.

    Thanks again,

    Ian

    I never used Norton Identity safe or any other password scheme.  Simply, I don't trust them.  I maintain complex passwords on paper.  It works for me.

    I used Norton Antivirus for years.  When they dropped the product several years back, I switched my clients to Bitdefender Antivirus+.  It is dramatically superior.  Problems are rare and protection is excellent which is clearly demonstrated by the fact that not a single one of those 150 has been infected since then.

    Hi CT,

    Apologies for the delay in responding, and many thanks for your comprehensive advice.  I'm aware of (and suffer from) the issues of conflict between Firefox and Norton, so take your point about ditching the comprehensive type of protection.  I'll have a good look at the linked documents.

    One reason I've stuck with Norton is that I've always found them very helpful when I get stuck, which may make you smile - ie if I didn't use Norton, I wouldn't get stuck in the first place!  I like the "insurance" provided by this arrangement but do note that my son, who's used AVG for years, never seems to have any issues, which may not be a coincidence.

    I also use a password manager (Lastpass since Norton Identity Safe stopped working on FF).  I'd be very worried about any "reduction" in protection that put security of this facility at risk.  What advie can you offer on that?

    Thanks again,

    Ian

    I suggest you re-think your security strategy:

    Which Antivirus product to choose?

    The “Security” software installed on your computer may be causing problems that can not be diagnosed or fixed.  Try removing it temporarily.

    This is a controversial topic, but your choice of AV software may be something you want to take a 2nd look at.  I suggest you visit this web site to get a sense of which AV software does the best job, depending on what kind of user you are:   http://www.av-comparatives.org/   This is a non-profit that has been around for a long time and I trust their results.  Download and read the 2015 summary report.  Their latest report: http://www.av-comparatives.org/wp-content/uploads/2016/07/avc\_prot\_2016a\_en.pdf

    When you interpret these results, keep in mind the difference between a product that detects 95% and another 99% of infections, is actually 5 times more likely to allow an infection.

    I am speaking from a great deal of experience.  I support 150 client computers.  I have been doing this for 14 years.  My clients NEVER have infections.

    The only products I will use or recommend are ANTIVIRUS-ONLY products.  Any product that is called complete protection, Internet security or deems itself to be a comprehensive security product is prohibited on my client computers.

    I have good reason for this. Over the years and hundreds of PCs, I’ve learned a lesson well.  That it is very difficult to diagnose and fix the problem(s) when components of an Internet Security product are actively working to prevent that diagnosis.  The software sees the technician (me in this case) as a threat.  I discovered that if I uninstalled that software, I am able to much more likely and quickly discover an fix the problem.  Antivirus ONLY products do not behave like this.

    The other components in these IS products (other than the AV itself) cause more problems than any benefit they bring and mostly work by shutting down the Windows component that does a very good job of that particular task anyway.

    It is the Antivirus software that you need.  It is actually allthat you need with Windows 7.

    Most of the big name suppliers much prefer to sell their all-in products because they can sell them for a higher price.  Some do not offer an antivirus only product.  Some push their all in ones and still sell the AV only product, but you may have to look for them.  There is at least one and it is either the best or close to it.

    Beware of products that try to actively engage you in the security process by asking your permission to run a program named xd43_45d*.exe, or the like.

    Do not use any product that claims to make your computer run better.  Virtually all of them are either bogus, themselves an infection, or put your computer at risk. Remove everything that claims to be there to prevent infections or claims to make your computer run better, with the singular exception of just one antivirus product.

    Note well.  You should never have more than one protection product installed.  Always ensure that you completely remove any and all protection software packages before installing a new one.  That includes software that may have come pre-installed on your computer when new.  Some products will conflict with one another, causing yet more problems.

    You cannot fully remove most any AV software by simply using the standard Windows 7 uninstall tool.  Most of the majors also publish a “removal tool” that gets the rest of it.  If you do not completely remove it, it will cause very hard to understand and diagnose problems.
