Hello,
If that doesn’t help, tell us more about your hard drive / SSDYou can start by deleting everything in the folder
C:\Windows\SoftwareDistribution\DownloadThen in the search area type Disk Cleanup and choose > C:
You will be able to select to clean the "system files", "Previous Windows installations" if present, as well as everything else.
Configure your Internet browser to download to a folder on D:\ if there is a D: partition or disk instead of your C:\Users\YourName\Downloads directory
You can store elsewhere on D:\ or on an external drive what is in your Personal subfolders of C:\Users\YourName\...
TreeSize Free can help you see what takes up the most space
Then clean with:
Wise Disk Cleaner

Then right-click on This PC > Properties > System Protection
Or press "Search" for systempropertiesprotection.exe
Choose C:\
Configure > Delete
Go back > Create

Thanking Fabul for the quick response, the processes are underway, then the reader D: is a 128 GB Sandisk microSD V30 A2, and the C: is 57 GB with 2.5 GB free and the D: is 119 GB with 111 GB free, thank you.

Also, run these two commands in Terminal (Admin)
dism.exe /online /Cleanup-Image /AnalyzeComponentStore
dism.exe /online /Cleanup-Image /StartComponentCleanup

But the Windows SSD must have at least 20 GB or more free to install.
Otherwise, reinstall from scratch
When you have the Windows ISO file, you can create a bootable USB drive with Rufus or Ventoy
In GPT mode for EFI (Secure Boot Support for Ventoy depending on how the BIOS is configured)
Start it using the PC's Boot Menu key
You can search on Google for "[Brand Model] Boot Menu Key"
Click (If offered): Previous version of the setup
Choose "Custom installation" (Not upgrade)
Delete all system partitions and create a new one (Deletes data). -

I’ll never reach 20GB, here are my partitions I think there are too many user accounts? I had a password issue. thank you

CrystalDiskInfo would inform us of the type of SSD (to see if it would be replaced by a larger one or not).

thanks, see you tomorrow

Hello,
64 GB storage on boards is generally soldered eMMC, which makes any upgrade impossible unless the PC also has a free drive slot.
Even if you store everything you can on the SD card itself—not of very large capacity—the system partition will quickly fill up with Windows and what is inevitable: there is no hope unless you go through an unofficial Windows version like Tiny or a lightweight Linux distribution.

Hello crystaldiskinfo can’t find my microSD card but can see my netac 500GB, can it do the job !!!

Hello,
You can install Windows 11 Home using Hasleo WinToUSB from the Windows ISO.
Boot from it via the BIOS boot option.
(If you want to replace your 64GB eMMC with this 500GB external drive that is always connected). -
Hello Fabul, thank you for your help. I’ll figure out how to proceed, thanks. I’m closing the topic, see you soon.

Hello, @phk30 StatusMember
A Giveaway for the WinToUSB Pro version is offered, for a limited time on several Giveaway sites (not affiliated):
Less limited than the Free version, with the Pro version you can also put Windows Pro on a USB key or external drive.
The license is I believe activated for one year with this promotion.
