Windows has detected an IP address conflict
Another computer on this network has the same IP address as this

Windows 'burp' or 'fart'. My thought would be a network lease change.
Sounds plausible. Would my wifi router (which I believe is what controls
my "network") instigate a lease refresh from time to time?
Not exactly. If you're using DHCP to manage IP addressing on your LAN it
will be the DHCP *client* (the PC) that instigates the request for a new
lease. The DHCP *server* (presumably in your router, but not technically
a requirement) will typically comply with the client request by either
extending the current lease or issuing a new lease.
You can probably see the lease duration by visiting the DHCP page in
your router, or by checking the lease on a PC shortly after it has been
renewed. The client will ask the server for a lease extension at the 50%
point, then again at the 75% point if the previous request was ignored.
There's more after that, but it shouldn't be required. In a client (PC),
you can do a manual release and renew, in case you want to see what a
full lease duration is.
When a renewal is requested and granted, is it an extension of the
existing lease, or is the existing one terminated and a new one taken
out? (Just curious; I don't seem to have any problem.)

By the way, do you have WiFi enabled on your router? It's possible, for
small values of possible, that someone else temporarily joined your
wireless network and they accidentally used the same IP that you were
Yes, the two computers are connected to the router by wifi. The same
thought had occurred to me - but it seems unlikely: I'm fairly rural
(put TN27 0DD into Google Maps - I'm the red roof on the north side): I
don't think any of my few neighbours would, and I think I'm sufficiently
far from the road to be out of range from there.
