Windows 10 Build 10240 update to Windows Update 1703

Assuming Windows 10 64-bit...

Please answer each of the following [admittedly tedious] diagnostic questions in a correspondingly-numbered list in your very next reply, preferably without quoting this post:

1. When (approx. date) did you purchase the HP computer?

2. Did the computer come with Windows 8 or Windows 8.1 preinstalled?

3. Was the upgrade to Windows 10 offered & installed via Windows Update or did you upgrade manually?

4a. Assuming a third-party anti-virus application/security suite is NOT installed => What Definitions versions are currently listed in Windows Defender's Update tab?

4b. What Definitions last updated date?

4c. What happens when you click on the UPDATE button on that tab?

4d. What third-party anti-malware applications (i.e., not Windows Defender!) are installed, if any?  What third-party firewall, if any?

5. Has a(nother) Norton application or a McAfee application EVER been installed on the computer since you bought it?

6. Have you ever run the Norton Removal Tool and/or the McAfee Consumer Products Removal Tool since you purchased the computer?

7. What OS Build of Windows 10 Version 1507 is currently installed (e.g., OS Build 10240.17533)?

• Press & hold the Windows Key and press the R key. In the RUN dialog, type WINVER and press the Enter key.

8. Is Adobe Flash Player version 26.0.0.151 installed? TEST HERE USING INTERNET EXPLORER OR EDGE ONLY! => http://www.adobe.com/software/flash/about/ 

9. Is Firefox version 55 (or higher) and/or Google Chrome version 60.3112.90 (or higher) or any other alternate browser installed?

10. Are you in the habit of using "Registry cleaners" (e.g., CCleaner's Registry Cleaner component; Registry Mechanic; System Mechanic; RegCure; RegClean Pro; Advanced SystemCare; Total System Care; Advanced System Optimizer; Comodo System Cleaner; Glary Utilities; Registry Booster; McAfee QuickClean; AVG Quick Clean; AVG PC TuneUp; Norton Registry Cleaner; Norton PC Tuneup; PCTools Optimiser; SpeedUpMyPC; FixMyPC; PC Doctor; TuneUp Utilities; WinMaximizer; WinSweeper; Wise Care 365; Wise Cleaner; Bitdefender OneClick Optimizer; etc.)?

Thank you. I asked because in your first post above you referenced an HP Envy 17 that was running Windows 8 at some point...

I have an HP Envy 17 with the upgraded sound and had issues with not having any sound after the upgrade to Windows 10. Not sure if the update problem is related to a sound card issue, but after upgrading my Windows 8 to Windows 10 [emphasis mine] a few years back, I would have issues with my Beats Audio sound playing from my laptop...

...and that sure sounds like the computer in your 25 January 2016 thread which, you told me, is that same computer as in this new thread where you told me the computer came with Windows 7 preinstalled, hence my puzzlement. That being said...

1. What anti-virus application or security suite was installed on the Windows 7 computer when you upgraded to Windows 10?

2. Can you successfully update Firefox to version 55 (or higher) manually? See https://support.mozilla.org/en-US/kb/update-firefox-latest-version 

3. Do you have backups of ALL the changes Bitdefender OneClick Optimizer has EVER made to the computer registry?

• Injudicious use of registry cleaners may be playing a role here. TIP: If you ever again think your Registry needs to be cleaned, repaired, boosted, tuned-up, cured, tweaked, fixed, maximized, "swept" or optimised (it doesn't), read this article and this older  (but still valid) one (and related links cited therein) then draw your own conclusions.

4. You're currently/still running Windows 10 Build 10240 [sic] - not Windows 10 Version 1507 (OS Build 10240.17443), is that correct?

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Chances are (99.99%) your HP computer came with a Norton free-trial or possibly a McAfee free-trial preinstalled. Doesn't matter if you never used it.

Fact: Norton and McAfee applications are notorious for not uninstalling (or upgrading) cleanly. The "leftovers" may be your troublemaker here.

1) My computer originally came with Windows 7. I am pretty sure that I had upgraded to Windows 8 before I downloaded the free update to Windows 10. I do not know what anti-virus I had at the time when I changed over to Windows 10.

2) Yes I just updated Firefox to 55.0.1 64-bit.

3) I doubt that I have all of the Bitdefender Optimizer files. I do not know where to find them and I had the regular Bitdefender anti-virus software when I started a few years back and then upgraded to the Total Security with the Optimizer feature.

4) When I go to Settings/System and click on About, it only states that I have Windows 10 Pro. It does not state what version or OS Build. When I click on the Windows key and the R button, the Winows version box displays a window that shows I have Windows 10 Build 10240.

5) Yes my computer had Norton Internet Security 2011 installed from the factory. How can I get rid of any leftovers?

OPTION A: Uninstall the Bitdefender application & reboot, make certain that Windows Defender and Windows Firewall are both enabled, download/run the Norton Removal Tool & reboot, reset Windows Update using the script (BAT file) in this tutorial & reboot again, then run a manual check for updates and see if any/all updates offered (e.g., KB4034668; KB4034662) will successfully install.

Note: Over the years we've learned that sometimes it's too late for the Norton and/or McAfee removal tools to "come to the rescue." This may be another one of those times.

OPTION B (Recommended): Do a clean install (not an upgrade or a Repair Install) of Windows 10 Version 1703, OS Build 15063.540). See https://www.tenforums.com/tutorials/1950-windows-10-clean-install.html

Note: The computer should NOT be connected to the internet or any local networks for extended periods (i.e., more than a minute or two) in its current state. All business & personal data (including online banking & credit-card passwords) should be considered at-risk, if not already compromised.

Wish I'd had better news for you.  Good luck!
