Must-have utilities for your Windows toolkit
How often do you think about the background systems that make your computer run smoothly and surely? As with most foundations, generally only when they're broken or faulty. And that's a shame. We've rounded up seven freeware utilities that can help you get (and keep) your Windows system in top shape.
We include some top picks in the disk defragger, file compressor, and all-around optimizer categories. There's a tool to recover lost data, and another to cleanly remove programs, including Registry leftovers. Check it out in our must-have utilities roundup.
Have other favorites that didn't make our list? Opine away in the comments.

good mix -> ccleaner, revo, ultradefrag and 7zip?!
The only SHAREWARE (initially used as freeware) that I bought was "Servant Salamander", because it completely handles 7ZIP, ZIP, ISO, RAR, UNDELETE, VIEW, EDIT, MAP, (UN) SPLIT, RENAME (all types), Windows explorer, Synchronize, Folder differences, Folder & drive sizes, Filename Attribute & case-changer, Network-access, De & encrypt, NTFS (un) compress, ... VERY much better than the originally specialized programs that offer these function, (free, share or commercial ware).

- Hello, as an experienced computer user, after many years of use, and using (and also trying) a lot of programs, I will suggest a software package of the best quality and totally free to have a clean, healthy and effective computer. The order in which they are presented is that of their use:

(8 Comments)1. Revo Uninstaller (clean unnecessary system files, among other tasks);
2. Auslogics Registry Cleaner;
3. Eusing Free Registry Cleaner (using it together with Auslogics Registry Cleaner will perfectly optimize the registry). Note: there is no incompatibility between these two programs, so you can use one after the other without any problem.
4. WinASO RegDefrag (only when the degree of fragmentation of the registry requires that operation);
5. Auslogics Disk Defrag.
My opinion is that these programs are the most reliable, professional and best quality that can currently be downloaded from the Internet. I mean the category of free software in the field of system optimization.
