Hi Rus & Welcome,
I will not mince words here. As I tell my clients, giving good advice is where things must start. To make a choice, certainly, @ this point in time, between XP & Windows7 is an absolute 'no brainer'... go w/ 7, hands down. Enjoy the Toshiba & leave it w/ 7. I say this for a number of reasons & on many levels.
XP is/was a fine OS & is like a fine horse whose time has come to be turned out to pasture.
Yes, support is ending; damn thing is 12 years old.
Security & a plethora of other Features are better & certainly more modern than XP.
Much, in terms of both hardware & definitely, software, is no longer made for XP.
Many ('now') important things will not run on XP.
I could go on & on but, just be glad you have 7 &...
