That is 3 versions old and no longer being updated by Adobe... so update to Win-10 at your own risk
Several have suggested that updating to Windows 10 should be done on a secondary computer until you are assured of its performance. While other posts very supportive message for no problems with Premiere Elements on Windows 10. But, I have not see any definition of what versions of Premiere Elements are supposed to be compatible with Windows 10.
Please consider the following very recent thread here on the subject of Premiere Elements compatibility with Windows 10.
Please review the thread and decide for yourself what is in your best interests in this regard. I realize the offer of free Windows 10 within a certain time frame are inviting, but....
If you have a busy Premiere Elements 10 workflow in progress on your present computer environment and do make the switch, as John suggests, you proceed at your own risk. I side on the side of wait and see and, if you must, look at Windows 10 on a secondary computer until you know you have a fairly reliable workflow with your version of Premiere Elements on Windows 10.
Thank you A.T. Romano, your information has been very helpful. I think I'll wait and see.
Thanks John T Smith for your good advice.
