My Windows 10 Version 20H2 will not install the update 0x80004005.

Good Morning,  Thankyou for the advice on the Bios update.  I will check if Asus have a Bios update for the two netbooks ( same models ) that I'm trying to update. 

Yes like you I have been talking about why MS have not realized that people want a simple OS without the Bloatwear. 

I will keep this updated , especially if there is a Bios update.

Thanks Again for taking the time to help.

Thanks for the suggestion of clearing the windows distribution area , I did this and downloaded again but still the stage where the updates get applied FAILS.

I have installed this version of the OS on 3 different laptops, one of which was a lowly based Celeron , but the lesser netbooks I am trying to update are ASUS netbooks with just 32gb ram and I have to use a USB device to help install. This worked for the previous 1909 install in 2019 so I have experience on these installs and I get the install to the point of it being applied but it just won't apply the changes !!

The netbooks will have to stay on 1909 until Microsoft release something that will work.

Thanks for the suggestion. 

I wish Microsoft read these and responded with some support.

I found a Microsoft bat file called WUReset2.0.bat on their web site.  Download it and right click and run as administrator.  I will run in a command prompt (Dos Box).  Then you reboot and this fixed my problem with installs.  Also make sure you check in services that your secondary login, storage service, and windows update are set to automatic.  I found out if these three services are not set to automatic, it affects Microsoft Store downloads and Adobe Photoshop updates also.  I just downloaded and installed update KB6003173 on Microsoft Windows 10 Professional 64-Bit on a Dell desktop and Dell Laptop with no problems.

Tried installing 20H2 on a laptop with low storage , tried standard install and tried manual using USB several times but the install gets to the same place says it's updating but stays on 0% for hours and gets nowhere , eventually have to stop the install and let it back itself out.

Checked system files all OK and the update says the machine is compatible with the update. 

I have installed this on other laptops and they have worked , but this low spec netbook just won't install the update even manually with the help of a USB thumbdrive. Struggled on previous major releases but they did install. 20H2 says it's compatible but something is clearly preventing the install .

With so many people reporting issues this needs work to support low spec netbooks. How about splitting the release into chunks that will make the New OS ?

Thanks man I'm going to do this as well. What do i need tondo the NAS backups and so. I dont want to lose everything andrreinstall all my programs. I have a lot of programs work related. Not even thinking about all my games.
