How to remove photos from desktop area

First of all, let me assure you that you are not alone to suffer with this issue. There are a large number of complaints about this problem.
It is believed that the issue is caused because of corrupted system files while upgrading to Windows 10, or the security updates downloaded. Restoring the corrupt files should solve the issues.
Microsoft is aware of this issue and has suggested the following methods -

Method 1
Run System File Checker -SFC. It scans your system files and restores the corrupted files if any to their original versions.

Method 2
Use a different account and login. If you do not have an additional account, create a new one and check if it solves the issue.

However, there are reports that both these solutions do not work for some users. I would advice you to go ahead and check if it works for your copy of Windows 10.
Some users have also suggested that it can be caused if you have AVG anti virus installed. If it is so, disable AVG and enable Windows defender.
As I said before, Microsoft is aware of the problem. With practically thousands of complaints pouring in, we can expect a fix soon.

Firstly, let me tell you the cause for this problem as it will be easy to resolve it afterwards, basically this problem is due to some of the corrupted files in the system. Therefore deleting or restoring the corrupt files may help.

You can resolve the problem by any of the following methods.

1. There is a app named System File Checker -SFC. It will scan your system files and restore the corrupted files afterwards.

Just run the System File Checker (SFC) app on your system. This is used to scan for all the corrupted files on your system which is creating this problem for you and then just restore all those corrupted files to their original versions.

Also you should disable any other antivirus which is running on your system. Rather just start working with the default Windows defender.
