Try this one:
IrfanView

Just make sure you uncheck any additional stuff when you install it, like Bing search bar and stuff like that. Cnet likes to add that sort of stuff.

It is simple to use. Open the file, press ctrl-R and choose the output size you want. You can select algorithm, I believe, to get the result you like.

I could do it for you but I'm on my phone now.

IrfanView has one great feature. It can resize (or modify in other ways) a batch of files, like for instance all pictures in a folder. It can output all the resulting files to a different folder to avoid irritating duplicates. This is great for sizing photos that you want to post online if you don't want them to be overly large. You can also remove meta data from jpegs when you save them. This reduces file size and also improves privacy when location data and other stuff isn't posted online.

I use it all the time. One thing it will not do is let you add stuff to the image, like circles and arrows to point at things. I personally use Paint for that simply because it's convenient and loads really fast as opposed to Gimp, which is a really powerful - and free - albeit bulky alternative to the Adobe products.
