I just clean installed this on a Dell D620 T2300 dual core 4GB of RAM. No issues at all. 32bit of course. It actually runs better than XP. What is slowing it down is the HDD. I have a 500 GB SSD on the way. Resume from standby is about 2 seconds. I've searching around for a cheap laptop because so many streaming programs and media programs won't run on XP and of course security. For what I use it for, streaming audio, it's good for another few years. I'd read previously about folks having major issues trying to run 10 on this system. Not anymore... Wow is all I can say because I was expecting problems.
