Hello,

First of all, I want to point out that I have already tried some of the solutions from the forum.

I have been trying for several days to upgrade Windows 10 Home version 1511 to version 20H2. The update keeps getting stuck (currently at 74% and I have no error code). I am on a Lenovo Ideapad 300.

I have already tried using the Windows Installation Assistant (the download occurs but the installation requires that the ongoing update be completed before it can start) and uninstalling Conexant SmartAudio HD (the update restarts after a reboot and the percentage changes but it also gets stuck).

Thank you in advance for your help.

Hello, what does that mean? I had to reset my computer to factory settings recently, maybe that's why.

hi

I had to reset my PC to factory settings recently, it might be due to that

and did it restore version 1511?

1511 is the second version of W10, there was 1507 first (but I think that was for insiders)

you can create a USB stick with the latest version 21H2 and install it

I just tried again through mediacreationtool (it fails telling me that another update is in progress and that I need to wait for its installation). Does it make a difference if I use the key?

hi

does it change anything if I go through the key?

you will install the latest version of W10 (21H2) right away

PS: you'll need to do a "clean install" (delete all partitions and create 1 or 2 new ones depending on the capacity of your HDD/SSD)

can you post a screenshot of your disk management? ==> click here

to access it, right-click on Start ==> disk management

if you have any questions...

Do I need to do anything special for the clean install or is it done via the key?

hi

For the clean install, do I need to do anything special or is it just via the USB drive?

It means 1 clean installation/new installation with data loss

You have a 1TB HDD, and you can create 2 partitions

1 for Windows (W10)

1 for your data (Data)

PS: is the PC originally running W10?

See you!

Like a factory reset then? Or by creating these two partitions do I keep my data?

Yes, under Windows 1 Family

Hello,

What you can try before a clean install:

If you have an antivirus other than Windows Defender, you need to uninstall it

=> Download the latest ISO version 32 or 64 depending on your PC

=> Copy it to your desktop

=> Disconnect from the internet

=> Double-click to mount it in the virtual drive (or right-click => Open with => Windows Explorer)

--> Right-click and run as administrator on setup.exe

--> Click Next

--> Click Accept

--> Click Install

I just tried and I'm encountering the same failure, still this message: "The Windows setup cannot be launched while another instance of the setup is already running. A feature update may be in progress. For more information, go to Windows update in the Settings app."

Try to see if under 1511, you can block updates for 7 days. If that's fine, do it, restart the PC, and check if they are indeed disabled.

In case you haven't seen it, I'm reminding you If you have an AV other than Windows Defender, you need to uninstall it

Then try again with the ISO.

If it still doesn't work, I'll leave you in the hands of BillMaxime for a clean install.

Thank you both very much, I finally succeeded. I uninstalled an old feature update, rebooted, and paused the updates, and I was able to update from the Windows ISO. (So my version 1511 was indeed due to the factory reset).

Have a nice evening!

Hi

No worries for the help, we were happy to assist :)

(so my version 1511 was indeed due to the factory reset).

Yes, and it's still present in disk management (20.89 GB)

If you use it again, your PC will revert to version 1511 of W10

Should I try to remove it from disk management in that case?

re

That would free up space, but then you need to "extend the main partition" C:\ so you don’t lose the 20.89 GB.

I also see you have the D:/ (Lenovo) partition of 25 GB... in disk management.
