I use Windows Photo Gallery. It is included as standard with some versions of Windows, or available to download free of charge as part of Windows Essentials. The latest version is Windows Photo Gallery 2012.
It allows you to browse through your photos easily.
There are several ways for marking photos you are interested in:
- Add a descriptive tag
- Flagging particular photos
- Add a star rating, i.e. 1 to 5
Then you can search by any of these, to find your best photos. Note the tag and ratings are stored within the photo files. So you can also search for them using Windows Explorer.
You can easily delete photos, though it's not quite single click - you have to click delete, then answer "Yes" to the prompt. This just moves the photo to the Recycle Bin, so it can be restored from there in the usual way.
