I may be getting a new computer. Will 9.3 run on Windows 10? I hope not so I have an excuse to upgrade.
9.3.x was not tested or certified on Windows 10 - the OS didn't exist when the product was released. While I'm not saying it absolutely won't work, I can say that it's not supported. In fact, support for 9.3.1 ended beginning of 2014. Hopefully that's leverage to upgrade!
Or start using ArcGIS Pro. But I'm assuming if you are still on 9.3.x that you are not on current maintenance, so don't already have ArcGIS Pro or the ArcGIS Online license (which is included if you are on maintenance).
In any case, I would say an upgrade is in order.
Nope! Get that upgrade!
Also, let them know that 9.3 is deprecated. You may want to request an upgrade on that as well.
Esri Support 10.6
