I face a strange issue, I have a lot of files in desktop while PC not responding I did restart, after restarting desktop icons and many files, folders were auto lost. is there any way to recover it. I am using windows 10 Pro. I am sure that I did not delete these files and folders.
You may try some data recovery tools. One tool I've used quite successfully in the past is from OnTrack (EasyRecovery Pro, IIRC), but it's not free.
A Google search will point you to a lot of tools.
You should also set up some backup in the future. Either Files history, the old Backup (as it appears now in the Control Panel in Win10) or even some script to copy to OneDrive, NAS, USB stick or cloud is better than nothing.
