Just curious can we upgrade now with the windows 10 preview or do we need way until its fully released ? thanks
You could save/backup a copy of your current OS, then upgrade to w10 preview to find out for yourself. If you don't like the result, just restore the previous OS.
This is a good way to try something new. I think I just need to backup operation system. right? Maybe I can try the "system backup" feature with my free easeus todo backup. I this way, I don't have to manually select the system files one by one to backup. Cheers!
It would be better to do a complete backup for the whole partition to an image. If something goes wrong, just restore from that image.
I was not talking about an Partition, I was talking about an whole HDD!! And please tell us: How big is the partition you backed up in MB/GB?
