Its really easy...
Go to Control Panel > System & Security > Restore your PC to 2-3 days back, you will get your data back
P.S - i personally did it and it worked
They don't have free trial how can i trust for 70$There are apps which can recover data..Just google it..I used one and it actually recovered my 100GB of data which i deleted unwillingly.But it was withing hours..If you are looking to recover data which you deleted a day ago then it might not be possible.

see this it works well it'll show you a bunch of files deleted and chances of recovering them as well as tries to recover the file which you want as well.
