Anniversary Update - a no go here

Found the culprit - it was Avast after all. You have to uninstall it completely and use avast cleaner tool then update will install just fine. Also if you install avast after the update - it will cause BSOD's anyway. Developers are already working for a fix though personally i feel like they let me down - i've already made a clean installation and wasted a lot of time because of that bug.

I just found that out by trying to install Avast. Your post with the cleaner tool saved my skin! Quite a let down from Avast when they have known about the Anniversary Update for quite a bit of time. I think I will just use Windows Defender from now on.

Thanks for that. Simply disabling Avast doesn't work - on my system anyway. Had to totally delete it and reboot. Then the update went as smooth as could be. Now using Defender.

All weird as my failed update left behind a file - 14393.160715-1616.rs1_release_CLIENTCombinedSL_RET_x64fre_en-us.esd - 2.47GB - which I assume could easily be turned into an ISO.

Yes, it is easy to convert .esd file into an ISO if you wish to.

There is a tutorial here: ESD to ISO - Create Bootable ISO from Windows 10 ESD File - Windows 10 Forums

or you can download the ISO direct from Microsoft from here: Windows 10 ISO

Wow... great to come across this. Microsoft fell flat on its face in the case of anti-virus programs. They should mandate you to uninstall your anti-virus prior to installing. How hard is that?

So, I uninstalled Avast! and was able to upgrade from 8.1 to 10. I then installed it again, and it worked fine. And now? With the Anniversary update, I get to 71% and it fails. I get a "STOP CODE: IRQL NOT LESS OR EQUAL." Microsoft support is atrociously USELESS in helping me. "Reformat your hard drive and install Windows 10 fresh." I don't have retail... I have OEM! Idiots.

So, what is this Avast cleaning tool? Is this something Avast provides?

The only way it worked for me was to totally uninstall Avast, reboot and then the AU went fine. Running now on Defender and Malwarebytes. Not sure if this has been fixed by Avast yet.

As far as I know Avast acknowledged the Issue and fixed it 2-3 days later ? but did not advertise it though a definition download splash screen and should have I think, as neither My Mother or Brother knew about it , so crashes for both.....

[fixed] Blue Screen (BSOD) - Windows 10 Anniversary Update on Skylake CPU

and you needed to Install the latest version for the Patch after using Avast Cleaner

Avast Uninstall Utility | Download aswClear for Avast Removal

New Versions

NEW August versions: 12.3.2279 + 2280


currently using .2280 here...

Great - thanks for this info. I've run the Avast! cleaner. I also found out a tip on how to allow software installs in Safe Mode (to help avoid any pesky service or driver clashes)... but it won't work for a Windows 10 system update.

Anyway, I'll go ahead for my 9th attempt at applying this anniversary update. I'm just about at my wit's end.

I ran the cleaner... didn't solve my problem. I get to 71% installation progress in the last phase, and then it aborts with the BSOD and a STOP CODE (IRQL NOT LESS OR EQUAL).

You need to update you computer Specs + OS :)

If you are trying windows Update , download the ISO and try a Inplace Upgrade as outlined the the Installation Tutorials Section.
