I was very excited about the launch of Windows 10. I upgraded my windows 8.1 PC to windows 10 as soon as it was officially launched in India. When I upgraded, my PC started taking long time in startup although I have 4GB ram in my PC, so that was really frustrating. Except slow startup there was no other problem and it worked fine but after few days the worst problem started coming it was whenever I used to work on my PC suddenly a blue screen appears with a message that your PC ran into problem and than my PC used to
restart. Whenever I used to do on any important work than this message used to come so I have to do that whole work from starting if I forget to save it. Not only this my start button stopped working so whenever I click on it than nothing happens.
Microsoft edge that is the default browser in windows 10 was also removed from my PC. When I tried to re-install it from Windows store than I came to know that window store is also not working. It used to open but I was unable to download anything from it as when ever I click on download button than nothing used to happen.
I tried to contact support but that was really challenging.
These are few problems that I have listed above. My experience was so bad with windows 10 that I switch to windows 10.
