Programs I always install after a fresh Windows installation:
CCleaner - Clean registry, unused files, etc.
CPU-Z - For CPU information.
GPU-Z - For GPU information. (Duh)
Core Temp - CPU temperature monitoring.
Notepad++ - A better Notepad.
KeePass - Password manager.
ImgBurn - To burn ISOs to CD/DVDs. Mostly use it to burn Windows because I always seem to misplace the damn DVD.
foobar2000 - Music player. Only recently started using it. It looks nice when you mod it.
VLC - Video player.
CCCP - A codec pack, comes with MPC-HC (Another video player).
7-zip - Pack/unpack zips, rars, 7z, etc. No real need for WinRAR with this.
Avast - Virus scanner.
Malwarebytes Anti-Malware Pro - Anti-malware scanner and real-time protection.
Comodo Firewall & Defense+ - Firewall and HIPS scanner/real-time protection.
DeepBurner - Burn files to CDs/DVDs or make music CDs. (Really a thing of the past now with phones and MP3 players.)
DropBox - File backup/sync.
FileZilla - For FTP.
WhoCrashed - Look at crash logs.
Left out ordinary things almost everyone knows about like Flash.
Why are you using Three real time protection software? One is enough.
A software firewall is really unnecessary. Are you experiencing slowdowns from time to time?
Some solid recommendations in here though.
My list:
HwMonitor - For temperature monitoring.
CPU-Z - CPU information.
GPU-Z - GPU information.
D3doverrider - the definite tool for forcing triple buffering and v-sync in any game.
SumatraPDF - lightweight pdf reader.
foobar2000 - audio player.
XBMC - video player.
iTunesfolderwatch - automatically add new songs to itunes for phone.
PuTTY - ssh client.
Defraggler - freeware defragmentation software.
CCleaner - maintenance.
Notepad++ - a better notepad.
Microsoft Security Essentials - antivirus.
Malwarebytes Anti-malware - only installed for scanning, never active. have it set to 'manual' in "services.msc".
Superantimalware - stupid name and not super reliable but i use it in combination of the other two in case they missed something. Same deal there, only installed for scanning, real time protection OFF (you don't need three real time protection). Services set to manual.
uTorrent - self explanatory.
Virtual Clonedrive - for handling isos and such.
WinRAR/7zip - for zipping/unzipping.
TikiOne Steam Cleaner - keeping your steam folder clean.
TFC - Temp File Cleaner by OldTimer.
WOL Magic Packet Sender - for sending a magic packet to my htpc in the living room and start it from my bedroom. Useful if you wanna remote connect to it and configure something.
WinDirStat - Finding out which folder is taking up all the space. Useful for small SSD's.
AIDA64 - Hardware information.
TotalCMD - File Management. It's been a life saver, especially on lanparties when connection between computers could fail from time to time.
http://ninite.com - Your favourite site for a fresh windows install.
http://www.blackviper.com/ - for keeping services running to a minimum. Not really worth it these days with 16gb ram but i still like to keep my system as efficient as possible.
