A lot of good progs/ apps mentioned here 7zip, CCleaner, Thunderbird, Evernote. Love these. I really love OneNote but seeing as MS haven't given us an Android version then I'll stick with Evernote.
An app I had never heard of till a day of two ago is PC Monitor. Found it mentioned on
Lifehacker. Install it on your pc (Windows and Linux) and your android phone/ iphone then you can monitor your pc from your phone. CPU Temp, CPU Usage, Memory Availability, Running Processes, Event Log, Command Prompt, Windows Update, Lock, Logoff, restart, Shut down your pc all from your droid. No gfx card temps yet but they say they are coming.
So neat and free. Windows Software from here

I am loving this app. It just works and is simple to use.
ps I am in now way affiliated with any company/ software mentioned above.
