“If I dont move on to the next version of windows I will lose any support for the previous version with a short period of time.”
Hogwash. They are only phasing out support for XP next year, and it was released in 2001. That’s 12 years of support. If they follow a similar time frame, you can use W7 and get support until 2021.
The support given XP is minimal. I have two computers that still run XP and the only support is in the area of security. NO OS upgrades for many years.
