Computers using Windows finally after DOS kept crashing (8)

I believe the answer is:

desktops

I'm a little stuck... Click here to teach me more about this clue!

'computers' is the definition.
I don't know anything about this answer so I cannot judge whether this works.

'windows finally after dos kept crashing' is the wordplay.
'finally' says to take the final letters.
'after' means one lot of letters go next to another.
'crashing' is an anagram indicator.
The final letter of 'windows' is 's'.
'dos'+'kept'='doskept'
'doskept' is an anagram of 'desktop'.
's' after 'desktop' is 'DESKTOPS'.

'using' is the link.

Can you help me to learn more?

(Another definition for desktops that I've seen is " Working surfaces".)

I've seen this clue in The Sunday Times and The Times.
