[Q] Avoid 8.1 for Surface RT when updating topic

First post ever. Wanted to post it here but wasn't allowed due to some rules: http://forum.xda-developers.com/show....php?t=2092348

Anyway, wonder if you someone could point out which updates (windows updates) should not be installed for the surface RT if you don't want to update it to 8.1. Reason is that jailbreaks only works for 8.0. But some applications, for instance DosBox, seems to need some updates in order to work (or else according to some comments an error occurs which happens to me know). It has become a kind of catch 22 now; You should not update but if it should work you need to update.
Right now I have 123 different updates.

So the questions still stands: What update(s) should I avoid in order to keep the windows on 8.0? For intance, KB.... or updates released after some date.
I have tried to find any relevant info about this but without success.

EDIT: Sorry, just saw the thread probably belongs in "Surface RT General" forum. Me bad.

Thanks in advance.
