After windows 10 anniversary update my XPS 15-L521X became really slow, in particular with photoshop, illustrator, indesign. The fan it's always on. I recently upgraded ram from 8gb to 16gb and seems nothing changed. Do you suggest me to return to windows 7 or 8.1? I remember that performance was better with win 8.1. At the same time my XPS has now 5 years, so, maybe, the issue is not with the OS but with the machine itself? There is someone who test same problems?
Thanks in advance.
