I have asked to look at the above, which sort of runs, but in treacle

It has Win10 installed on it, it seems to have a reasonable spec. I'm
wondering if there should be a recovery CD for it, or if anyone knows
where I could download from and burn a CD?
First thing I'd do is boot it from a lightweight linux distro cd. Running from cd slows any OS down a lot, but not to the extent you describe. If it works that way, as I expect it will, wipe the hdd and install a suitable OS eg a lightweight linux. If you must go windows try an older lighter version.. The problem is most likely malware, so a disc format & reinstall of win10 might be enough, maybe.
And for a joke suggestion, win98 runs real fast on modern hardware

IT takes assorted tweaks just to get it to work.
