Need help resetting windows

Hi, is there a way to fully reset windows 10?
I've used the built in tools with windows to reset the pc and after it restarts things still remain - my desktop wallpaper is still the same, my user account is still there, most of all the problem I was trying to remove is still there too.
I've also tried the option to 'remove everything' (or some similar name) and after 4 hours of waiting it just gives the message that something went wrong and no changes have been made....

Is there any way to do a completely fresh install without having to format the entire thing and boot the installation media from usb?

Hi, it would be wise to check your disk to make sure there's no underlying cause.

E.g. HD Tune - smart parameters, can also do a surface scan (Error scan tab); Hard Disk Sentinel (trial) is very good.

If your disk is ok, you might wish to consider an in-place upgrade repair install rather than wiping everything:

This keeps all programs and data and most settings.
You will need an iso of the same build, base language and 'bitness' (x64 or x32) as appropriate- you can use heidoc's tool to get older ones if necessary.

Perhaps an in-place upgrade repair install is what you seek here?


Reset:
From the extensive Tutorial section here:
Reset etc:

- but it seems your Windows may be corrupt, or your disk faulty, and this fails from what you say.

Clean install
Failing that, you can do a clean install- which (and see tutorial) means deleting all (up to 4) Windows partitions:

You will need to download an iso to do that, freely available.

Those are the sledgehammer approaches- naturally we don't know what problems you are actually experiencing.
Less drastic approaches start with
a. check the disk
b. run chkdsk c: /scan from an admin command prompt
c. run SFC /SCANNOW from an admin command prompt

thanks for all that info, I'll give it another try :)
