I try to delete stuff but thats not working. There is some kind of backup and storage going on that Id like removed.

Here is my serious tip. Buy an external USB-Harddrive and safe your personal files. Then run a clean Installation. Your question proves that you don't have the know how to do troubleshooting.

Hello
what is the exact model of your computer
maybe it is better not to try windows 11

Windows 11 on devices that don't meet minimum system requirements 
We risk having serious problems, probably updates, security problems, we do not really know what else

If the installation goes well for some, for others it can be complicated
go back to windows 10 - HP Support Community - 8200306

Hp also might not provide any update:

Think carefully, before taking the risk, see the experiences of other users, see if it can be interesting, or if you can wait to have a new computer later, 100% compatible!
Windows 10 remains one of the best systems, and can be used for quite a while.

I have performed the installation with a compatible computer ..
And I can not take full advantage of the more or less interesting features, because you have to have a certain material
https://www.microsoft.com/en-us/windows/windows-11-specifications
So far, so there is nothing extraordinary about this system
So if the computer is not compatible, you have little interest in using it ..
In some cases, we can have more problem than something else (performance etc), it is better to wait until most of the bugs are solved.
And even better to have a 100% compatible computer, in order to be able to take advantage of the available features
Now, if you want to give it a try, first plan to use specialized software, and make a ghost copy of your installation.

Some elements may therefore not apply to you 
To be able to answer you effectively, we need some information

we need the exact model of your computer, and the product number
To find it follow this
for a desktop computer

HP Desktop PCs - How Do I Find My Model Number or Product Number? | HP® Customer Support
and for a laptop
HP Notebook PCs - How Do I Find My Product Name or Number? | HP® Customer Support

Give the full name with the product number P / N

this is not a model:
HP Desktop M01-F1xxx
the requested product number must look like this
Product Number: 9EE50AA # ABA
the model corresponding to this number will therefore be
HP Desktop - M01-F1033wb
