 Best Free Portable Apps for Cleanup & Tuning

Best Free Portable All-in-one PC Tune-up:

Comodo System Cleaner -- Home | Download | Support | Editor Review

Description: Comodo System Cleaner continues to improve since the first time I saw it. It has three main cleaners (disk, privacy, registry) and a "clean my computer" one-click button to run them all. It uses a two step "safe delete or registry protection" procedure to prevent you from deleting essential files or registry entries, including a built-in backup and restore tab and a restart of the computer. The second step requires you to restart the computer before finalizing its actions. In addition, it allows you to set a new restore point before cleaning for a third safety precaution. Why all the fuss? Well, automated cleaning is risky business, so also be sure to have a good backup of your files and a drive image.

It also comes with many other cleaning and system utilities. You can manage autorun entries (startup-up programs, services, etc.), erase selected files/folders or the free space, view system information, uninstall software, and tweak system settings. It downloads a help file through an updater if you need it; otherwise, the internal updater is disabled in the portable version. Creates files and folders in your user folder ("ComodoGroup" in "roaming").

Best Free Portable Disk Defragmenter:

Defraggler -- Home | Download | Support | Editor Review

Description: "A solid combination of performance, stability and usability from Piriform. With a very clean interface design based on the common Windows defrag interface, Defraggler is incredibly easy to use and offers all the options you need to keep your machine running smoothly – including the ability to defragment individual files and folders as well as an in-built defragmentation scheduler." Verified TruPortable.

All of the portable websites have ignored MyDefrag's existence so far. It doesn't help that its author argues against any positive reasons for someone wanting to have a "no-install" version (here). However, MyDefragGUI ignores JK's reservations and makes MyDefrag portable. MyDefragGUI is an alternate interface designed to make running MyDefrag easier. It's an excellent choice for boot optimization and multiple sorting/optimizing scripts. The daily optimization script in particular helps to balance the wear and tear caused by defragging itself with the benefits of defragging (in saving wear and tear over time).

Best Free Portable File Cleaner:

CCleaner Portable -- Home | Download | Support | Editor Review

Description: One of the essentials for a portable collection and getting closer and closer to an all-in-one utility. It hits several of our articles for different purposes and could compete for many more. "It's very effective in freeing up disk space by removing unused and temporary files, cookies, Recycle bin entries, history and cache files in many applications, and much more."

Plus it cleans the registry, manages the startup, uninstalls software, securely erases anything it deletes, wipes the free space and MFT, deletes old system restore points, manages cookies, or runs as a task with the /AUTO command argument. Verified TruPortable.

Best Free Portable Memory Optimizer:

CleanMem -- Download | Forum | Editor Review

Description: Some people argue that memory optimizers aren't needed anymore. "But CleanMem seems to work and it helps you automatically recover memory and file cache space to improve performance. The program will install and run every 30 min via the windows task scheduler. It doesn't run in the background constantly."

Just extract the ZIP download file to a folder of your choice and click "schtasks.exe" for it to run automatically by the task scheduler, but don't use either of the BAT files since they aren't needed in the portable version and they install files to c:\windows\system32.

Best Free Portable Secure Delete:

Portable Eraser -- Home | Download | Forum | Editor Review

Description: It's easy to recover deleted files unless you routinely wipe the file data away. Eraser "overwrites the data area with your choice of random data patterns, and also wipes data in the recycling bin, unused disk space, and a number of other places where data can secretly lurk." Creates an INI file in C:\windows.

Many file cleaners include secure erasing such as CCleaner and Revo Uninstaller. But even if you securely delete files with something like CCleaner, I recommend regular free space wiping to increase the effectiveness of erasure (1 pass is usually enough on modern drives).

Best Free Portable Program Uninstaller:

Revo Uninstaller -- Home | Download | FAQ | Editor Review

Description: Revo uninstalls software and scans for any leftover remnants. It's "the only freeware product I know of that will make a decent job of cleaning up a failed install." Additionally, click "Tools" for its startup manager, list of windows tools, and junk files scanner. Don't miss the "Tracks Cleaner" right below the Junk Scanner for its several other cleaners (browser cleaner, Office cleaner, Windows cleaner, free space wiper, file shredder). Verified TruPortable.

Best Free Portable Startup Manager:

Autoruns -- Download or Run Online | Forum | Editor Review

Description: If you have many unnecessary startup programs and tray icons hogging your RAM space and slowing your PC, then you can get many specialized startup managers beyond CCleaner and Revo above. For users who want to manage all possible startups, Autoruns is a gem. It allows you to manage auto start programs by simply unchecking them (so you can turn them back on if you really did need them), but you can also manage scheduled tasks, services, drivers, sidebar gadgets, and many other things. Writes settings to registry.

Best Free Portable Windows Tweaker:

Ultimate Windows Tweaker -- Download | Support | Editor Review

Description: Sometimes windows comes with more extras than you need or want, and sometimes its default applications have a mind of their own and represent a privacy or control threat to the user! You won't be able to completely get rid of Windows Media Player or Internet explorer with this tool, but it takes a good shot at them!

"UWT is a well equipped tweaker utility that supports Vista/Windows 7 (32/64 bit). Besides others it covers user account, security, performance and internet tweaking. The only thing that did not work on my 32Bit Vista Home Premium was the Network tweaking option. I received an error message and the page would not show. Still, UWT is a great tweaking utility worth a try." Copies files/folders to the system directory.

Best Free Portable Software Update Monitor

yes, filehippo is great. but Sumo is far better (free and has portable) and detects everything on your system, not just filehippo software.

can i get kcsoftware on my android as my laptop wont downlad

i don't consider Comodo System Cleaner truly portable. i used it and liked it. eventually removed it. months later upon investigation found parts of 2 drivers on my system that google revealed came from CSC (was hard to find in google though). you can find them yourself with anvir taskmanager free (go to bottom and press drivers) or with esets free taskmanager tool (maybe even with free runscanner). drivers name was just a bunch of small case letters.

The ClamWinPortableDBUpdate link above leads to a non secure site, so please have a look into it.

Also, I would like to mention that there is a portable version for Superantispyware.

Thank you.

thanks, Superantispyware portable link is there . there no longer seems to be a secure site for ClamWinPortableDBUpdate
