I still have Windows 7 too! MS keep trying to get people to upgrade to Windows 10, it's free until end of July but very few people like it and still prefer Windows 7, it's riddled with problems.
I first thought the April 2012 shot showed the tree dead! It does seem odd to be so late, unless it was the beginning of April.
Another trick for getting closer shots is to use the magnifier before taking a snip. You can do that from the small cog top right or next to the star favourites symbol, open "zoom 100%" and you can change it but don't forget to change it back for that tab. I also use PhotoRazor to enlarge photos, it's brilliant.
