If we’re still running Win-7 Pro x64, is this a “worry”?
As a fellow Win 7 user (til the day I die, but I'm old :), this is most definitely not a worry.
Win 7 Pro x64 continues to hum along on my Lenovo S30 ThinkStation without a problem.
Solid state disks are a blessing. No noise, minimal heat, boot in 20 or so seconds. What's not to like :)
