I recently bought a new Lenovo computer pre-loaded with Windows 10. I have downloaded Photo Gallery as part of 2012 Essentials. It now shows all my photos, but every time I start to add captions or tags, I get a message saying Windows Photo Gallery has stopped working, and Microsoft will inform me when the problem has been resolved. I have tried deleting the programme and downloading afresh, but it has not helped. What can I do?
