Favorite Computer Tips/Tricks/Etc

I'm curious what others have done to make their life in front of a computer easier. I'm always looking for a trick or two to make things better overall. And there are so many new technologies that I cannot keep up. All of this shared resources/cloud stuff, etc is moving faster than I have time for.
Here are a few things that have made my life easier. As a way of background, I work on three different computers (work desktop, home desktop, and laptop). My kids have computers and live with me and in their own places. I do different projects that I keep separated (one of my roles is MS Access developer). I use Windows 7.
Microsoft Mesh - I know there are many tools like this, some with features I wish Mesh had. The thing I like about Mesh is that it is driven off of Windows Live login, which many people have and makes sharing easier. Also, I can apply Mesh to any folder, not just a main folder with it's sub-folders. Mesh allows me to keep a copy of folders in the cloud, as well as exact copies of folders on each of my machines and anyone I share a folder with. So if I am working on my laptop, I can close a file and soon it will be copied to my desktops. If the kids are working on homework and need my help or need to print, they throw the file in Mesh and I open it or they go to a computer with a printer. I send my parents and kids files with our shared folders. This is by far the biggest help in my life, computer-wise. I have maybe 12 Mesh folders for different purposes. Some save to the cloud, some are just computer to computer.
Solid State Drive - do it. Reboots are seconds, not minutes. Just remember to put all your data on a separate, standard drive.
Folder links in the Favorites area of Windows Explorer - I put my most-accessed folders here for quick access. I also have 2 additional toolbars in my start bar area (one for semi-often used programs and one for important documents or files). Put as much as you can in a spot with as few clicks as possible.
Online backup - I use BackBlaze, but there are a number of services (e.g. Carbonite). This has saved me a few times when my kids accidentally delete something. I think I pay $40 a year - most are around $40-$50 a year and back up all your files in the background.
Virus/MalWare - I use Malwarebytes to keep all the annoying shit (Malware) off my computer and it is very good. I use Avast as a free service for virus protection. I could probably spend more and lock this down. But with as many computers as we have, the licensing is too much.
Photos - So when you take a photo with today's cameras the size can range anywhere from 4MB to 12 MB per picture. And at the rate people take pictures, that adds up very fast. I use a tool called Advanced JPEG Compressor to shrink file size. In a batch run (all pictures at once) I tell it to reduce the quality of the picture 1 or 2%. To the eye, this is nothing. By going through the motion and re-writing the file it shrinks the file WAY down. Generally an 8 MB file gets written as 1/2 to 1 MB. Multiplied by hundreds or thousands of pictures, it makes a huge difference on space and emailing.
Music - For tagging and cleaning tags I use Tag & Rename. Great tool. For renaming large quantities of files I use Flash Renamer. Especially useful if you keep your music/pictures organized.
So those are my shortcuts in my computer life. Would be interested in yours.
