Hasn't steam stopped working on XP since 2016 or something like that? That's when my old computer, which dualbooted in 7 and XP, finally broke down and I had to buy a new one. And I remember at that time, I had to use an old version of the steam client on XP. And every once in a while, the client would update, and stop working. So I deleted the new version and just extracted the old version from an archive to access my account. The only game I was still playing on STEAM at that time was Pinball FX2.
Steam still worked on windows xp but it didn't work fully. Steam will fully stop working for win xp users on 2019 january 1.
There was something with content servers unreacheble or something, but that was solvable by editing one file which i had more info here: https://www.gog.com/forum/general/content_servers_unreachable_on_steam_cant_install_any_games
The only reason i needed steam this time was playing hybris pulse of ruin and since i beaten it i really don't use steam currently anymore. Maybe on a better pc with a different os i will use steam again.
Too bad uncles 2009 better pc which someone though was a smart idea to install win 10 the motherboard burned if that was true, updates happened and it was only slower and slower after each update until it was too slow.
So then i got another pc which sits on my table rather than on the floor which is only a rug. Wonder if i need to redesign my room before buying any new pcs since i am kinda afraid it will burn again.
