Audio Expert http://www.udse.de/audioexpert

Cue Splitter http://www.medieval.it/cuesplitter-pc/menu-id-71.html

Dir It https://toolsandmore.de/Central/Produkte/Software/Datei-Tools/Dir-it/
just drag and drop a lot of files to the tool to get the file location/names in your clipboard

RegShot http://sourceforge.net/projects/regshot/
find what has changed in your registry

Some extra stuff that i like to use. 

To replace windows picture viewer and that metro photo viewer:
JPEGView http://sourceforge.net/projects/jpegview/

To replace Wordpad and Notepad (saw u allready had this in your list after i posted) :
Notepad++ http://notepad-plus-plus.org/

To replace windows paint:
Paint.net http://www.getpaint.net/download.html

For converting video, audio or images (Best i've used, to and from everything):
SUPER © http://www.erightsoft.com/SUPER.html

A VERY handy tool everyone that has a stock pile of Movies and TV Series needs to have.

THE RENAMER
http://www.therenamer.com/

It uses various online data bases to rename, number and add details such as year of creation and many more if you need it too

Thanks for sharings. I tried many software. There is some of my different recommandations:

XnView (Fast, minimal, useful picture viewer)

Mozilla Thunderbird (I think its better than Opera Mail because Opera has many problems)

Qbittorent (Stable, efficient and CPU friendly bittorent client)

MyDefrag (Obviusly best freeware defrag software for performance)

Process Hacker (Very fast-useful task manager)

LAV Filters Megamix (This is compilated media player which includes PotPlayer-best video player, Media Player Classic with LAV Filters, MadVR-best codec ever, xySubFilter, DirectVobSub)
LAV Filters Megamix

Process Monitor: Sysinternal's great tool shows all Windows API-calls in realtime. Comes with powerful filters. The ideal tool to trace errors and program behavior.

Process Explorer: TaskManager replacement with vast options by Sysinternal

Autoruns: Lists all processes that start with Windows and offers checkboxes for easy deactivation

HiJackThis: Lists processes that start at system start and other features to track malware

QTWeb: Ultra-tiny browser complete with built in adblocker. Portable, single executable and less than 8MB. Runs even off a CD

Search Everything: Ultra-fast, tiny and portable search tool. Just enter the name of the file you're looking for and it filters its search list in real time. Tracks TOC changes through NTFS-queries. No search indexing service required

Locate32: Another great portable search tool. It doesn't support realtime search. Instead it creates a snapshot of your system's current file setup. Afterwards you can search through the snapshot in realtime with tons of search options such as size, date and file content. Also nice to have to have a snapshot around in case of a hard drive fail. This way you'll know exactly which files you lost

Daum Potplayer: Moderately small media player that supports hardware accelerated decoding as well as a ton of other audio and video filters for playback. Comes with built in filters, but also supports directshow filters.

DNSJumper: Small tool that allows you to switch between different DNS without having to change those manually.

EasyBCD: Invaluable tool to manage your BCD. Huge set of features. Allows you to boot basically everything from your Intel PC: Windows, Linux, ISOs, VHDs, Floppy Images etc.

VisualBCD: Small tool with a low level approach to BCD editing. It doesn't support as many features as EasyBCD, but it does support some that EasyBCD doesn't and that allowed me to fix problems I couldn't have otherwise.

Filezilla: Great FTP-Server/Client.

Flashget: Pretty small download manager with integrated Emule and torrent client. Has been around since the 90s. Still useful when downloading from slow websites. Supports downloading media such as Youtube videos with the Flashgot plugin. I suggest using the 1.9 version over the 3.x one. since it's less bloated. The torrent and emule client functionality is neat, but no real replacement for a dedicated client, but nice for those who only need such functionality occasionally.

NVidia Inspector: Tiny portable tool to manage your Nvidia graphics card. Allows you to set clocks, voltages and access hidden graphics options. You can also force your graphics card's mode through it (idle, 2D, 3D).

Psiphon: Small portable proxy/VPN. Automated proxy. No installation necessary. Connects you via SSH, SSH+ or VPN.


Browser Plugins:

- uBlock Origin: Ultra-performant adblocker that supports Adblock Plus filter lists plus many more. Uses less memory than ABP and runs faster, blocks more stuff and has a better feature to select website parts to create automatic block filters. Supports Chrome and Firefox.

- FlashGot: Plugin that integrates a ton of download managers into Firefox. It not just catches downloads from websites that try to hide their links and routes them to the download manager of your choice, it also allows you to download media such as audio and video streams, as well as batch downloads of all links/selected links on a website.

Adding some tools not here, main criteria is "low resource usage":

1) Text editor: Notepad2-mod: https://xhmikosr.github.io/notepad2-mod/
2) Microsoft Snip: https://mix.office.com/snip
3) Image viewer: IrfanView: http://www.irfanview.com/
4) *Not freeware, but priceless(file manager, ftp client, cloud accounts management via plugins, bulk file rename, cooking steak): Total commander: http://www.ghisler.com/
5) Browser: Firefox light http://sourceforge.net/projects/lightfirefox/
