Upgrading will be a shot in the dark......you will not know what you are going to get (or not get) until you have actually done the upgrade.
I am also looking at at your cpu....1.8 Ghz...?....that is quite small. In theory it should work. But thats the theory. It would be a possible source of disappointment. Slowness especially.
However.....the story goes that you can always 'rollback' to your previous operating system.
This has had its problems /dramas.....the forum here is full of them. Some go smoothly...some not so smoothly.
Sorry to be such a misery guts, but the upgrade can be an experience to put and keep a smile on your face or it can also be just the opposite.
If you have an Image backup on an external hard drive......I would go for it and try your luck....that way you can always go back easily by simply restoring via the backup program.
if you wish to play safe, then stay with windows 8.1, and save for a new laptop.
It is probably a bit late in the "free" period to be making a decision under that pressure.

It has been said that time heals all wounds. I don't agree. The wounds remain. Time - the mind, protecting its sanity - covers them with some scar tissue and the pain lessens, but it is never gone. Rose Kennedy
