You really should update to at least Win 7 if XP is your daily driver. As MS is no longer providing any security updates, flaws in the O/S itself are no longer being patched. This is more than true now in the times of Spectre and Meltdown.
On a serious note, i do plan to update my O/S and computer(been saying that for the last 6 years though). A lot of general software is starting to become obsolete for XP. If it wasn't for chrome and Avira, i would of updating a while back, as most of my webpages would not load and most programs ended support for XP a while back, i still got some on line protection atm.
Most of the sims i use, still support XP. However, another sim that i generally use, is ending total support for XP in the coming months, as that sim is moving over to Monogame.
Guess my time on XP is finally coming to an end!
Thanks
