running windows 10, and windows 11 tries to download. it ends up failing and bluescreens.
it leaves behind very large files in the installer folder
how can i clear all these out
First of all, there's no such thing as BSOD because of low disk space when upgrading. Windows Setup only needs ~10gb of free space to start an upgrade from Windows 10 to Windows 11, and the installer checks (and fails) if you have less than 10gb available. No BSOD during the process. You probably have a faulty SSD.
Second, inside the %systemroot%\Installer folder there are cached msi installers from all msi programs that you have installed on your computer.
Try entering inside this folder and hover your mouse over the msi file to see the description of the installer. This way you will see what programs are occupying all the space. If you delete the files inside the %systemroot%\Installer, you won't be able to uninstall/repair them.
Hi,
You can carry out Disk Cleanup on the C Drive - Right click C Drive Properties - DiskCleanup - Cleanup System Files and select the downloaded files.

there is nothing to clean up unfortunately..
i looked there, and have looked throughout the drive for other files to remove.
i had 3.8gb free, and the windows update starts, it downloads a few files, and then blue screens
there are like 28 files that are the same size of 128mb, and 11 files of like 190mb files
Hi,
In this case you need to download Treesize a freeware for home use and it will provide details of the files and folders that is using the space, you can right click and delete from that console of Treesize.

i have treesize, and that is the picture i attached - there is 135gb in the installer folder, but i am unsure if i can remove or what consequences that will have
Hi,
Okay makes sense, I will take a cautious approach to this and follow this guide from Microsoft. can-you-safely-delete-files-in-the-windirinstaller-directory
However if the files are taking up space and causing issues I would clear up recent downloaded files and try to movde data to external disk temporarily so the Windows 11 can be downloaded.
Also check these commands and article for help.
