There is not enough memory or resources, MS Paint

I also went to the path: Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Applets\Paint
but don't know what to delete.

Your first step should not be to edit the registry, this may not be the root cause.

The message says 'not enough memory or resources' so you should look at that first, the problem may be with the system, not Paint itself. Sometimes system resources do not get released for re-use once no longer needed by an app. Select Restart from the power button on Start, this will ensure Windows does a full start from cold and will have all resources available.

How much RAM do you have? What size is your page file? If you have not already done so, set the page file to 'System managed', Step 8 in this tutorial.

What does Task Manager show for Memory on its Performance tab while you use Paint? What is the size of the image you are editing?

If you still want to try editing the registry, then close Paint and open Regedit. Go to Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Applets\Paint. In the left hand column, right-click on Paint and select Export to save the key as a .reg file (in case you need to restore it). Then right-click on Paint and delete it. The key and all its sub-keys will be recreated when you next open Paint.
