Hello Guys, I am kinda new here. So ,sorry if this is not the right place to post this. I use a Lenovo Y410P which came with windows 8 and I updated it to 10, when it came out. After the update startup is really really slow (windows 8 was slow as well) and I see that the disk usage is 100% all the time. I tried everything on the internet I could to see if I can solve the 100% disk usage but in vain. I bought this laptop so I don't need to deal with the slower computer I had earlier. So, now I was thinking maybe a downgrade to Win7 would help me on this case? Please let me know your opinion on this? If thats a good idea, can I just buy a Win7 from amazon and install it by myself or should I contact Lenovo for the downgrade? Thanks in advance for the advices guys, looking forward to hearing from you.
