laptop misbehaving after update to window 10

I have laptop of Lenovo Z50 with 4 GB RAM

Initially after updating it to window 10 it was working properly but suddenly after some time it started misbehaving

every time I open my Laptop, it shows preparing windows on the screen and takes time to open the laptop

the most important thing is that its start menu is misbehaving

Start menu is not showing all the applications

if I make any change in my laptop then that change will automatically be changed to original one after I start my laptop again like if I change wallpaper of it then that wallpaper will be removed automatically after I start my laptop again

Please help me regarding this.
