Is it possible for me to update to windows 10

[Sammyia]

my desktop runs so slow is it possible to update to windows 10 and how?

Hello
Sorry, but you may think that this will be better with the installation of windows 10
This pc, is of a very very fast configuration!
It is only equipped with only 3 GB of RAM memory
an inefficient processor
At best if windows is a slow one, you can try a factory re installation, it can give it a little boost
Then I think that we should not spend too much money on this computer!

@Sammyia 

I heartily support what @Prométhée has already told you about not spending much money on this.

Wanted to add some limitations you may not be aware of:

1) Memory -- you are running 32-bit, which limits you to accessing about 3.5GB of memory, regardless of how much you have installed.  So, adding more memory is going to provide no improvement.

2) Processor -- the one you have is soldered to the motherboard, not socketed -- so you can't replace it with a faster processor

3) Windows version -- you are using 32-bit Windows, and while it is POSSIBLE to upgrade that to Windows 10, that will not buy you anything because you can't upgrade a 32-bit version of one Windows OS to a 64-bit version of the same, or another, version Windows OS.

4) Performance, given your low-end processor and RAM limits, it is very unlikely that Upgrading to Win10 will accomplish anything -- and that is presuming such an upgrade would work.  I have a bunch of OLDER PCs that came with Win7, have been upgraded to Win10, and in all those cases, they run faster under the older Win7.

yes, as I said @Sammyia the best option to find a pc can be a little faster, will be to reinstall windows 7
So if you want to try to save all your personal data, on a usb hard drive for example!

Here are the HP procedures:

Performing an HP System Recovery

if possible you have to create  recovery discs
