Ten Free Tech Support Tools

Category: Software

A well-prepared scout never goes anywhere without his trusty Swiss army knife. Similarly, you need a portable arsenal of troubleshooting tools to solve common computer problems. You never know when your laptop, or a friend's computer, may start acting up. Load up these free tech support utilities onto a USB flash drive and they'll think you're a tech support superhero!

Ten Portable Tech Support Software Utilities

All of these handy programs are free, but they also share another important common factor. They don't require any installation, because they're designed to be portable. The ability to run them directly from the USB drive is important for several reasons. First, on a badly infected system, sometimes you can't even install new software. A virus may be blocking the introduction of new software, or the Windows installer may be broken. Also, some programs require administrator privileges to install, which presents a hurdle if the admin password is unknown.

#1 -- Malware infection (viruses, spyware and other nasties) is one of the most common problems. Some malware even disables the security software found on the infected hard drive. In such cases, a portable antimalware program stored safely on a USB drive is a lifesaver. ClamWin Portable is a free antivirus for Windows XP/Vista/Win7/Win8 that can be run from a USB drive without installing it on the target system. ClamWin is open-source, detects and eliminates viruses and spyware; automatically updates its signature database; can be integrated with Windows Explorer to scan individual files; and can strip infected attachments from Outlook email.

Tech Support Software

#2 -- If you run into a problem that ClamWin can't fix, check out the portable version of SpyBot Search and Destroy. This tool has been around for years, and has a strong reputation for detecting and removing spyware and other forms of malware.

#3 -- One form of malware that's particulary difficult to detect and remove is the rootkit. On infected systems, it can't hurt to use a dedicated rootkit removal tool such as Kaspersky's TDSSKiller Portable. Just remember this isn't a substitute for a full anti-virus tool.

#4 -- If your hard drive appears to be mangled, don't give up hope before trying TestDisk. This powerful portable utility can recover lost hard drive partitions, and fix problems with drives that won't boot up. TestDisk will analyze your disk, partitions, boot sector, and can help you recover deleted files, and even rebuild scrambled file systems.

#5 -- Sometimes all a sluggish system needs is a good disk defragmentation. Ultimate Defrag is a free portable disk defragger that lets you defragment any drive in a variety of ways. In addition to stitching fragmented files back together, this app can optimize the placement of frequently used files on your drive. After downloading and installing Ultimate Defrag, just copy its entire directory over to your USB drive. (For even more speed tips, see my article Make Windows Run Faster.)

#6 -- A bloated or disorganized Windows registry is another common cause of poor system performance. In more serious cases, a corrupted registry will prevent Windows from starting up. The Wise Registry Cleaner Free Portable edition scans the registry and fixes obsolete or incorrect registry entries. It makes a backup of the registry before scanning, so you can roll back changes if necessary. This program can be launched directly from a USB drive.

#7,8 -- Some programs cannot be uninstalled by the Windows "Add/Remove Programs" function. For those stubborn clingers, try the Revo Uninstaller program. Note the link to the portable version at the bottom of the download page. If you are trying to rid a brand-new system of all the unnecessary junk programs that came installed on it, try the free PC Decrapifier utility. Both can be launched directly from a USB drive.

#9 -- In cases where Internet Explorer or Edge is not functioning, and no other browser is installed, the portable version of Chrome or Mozilla Firefox will help you get access to the Web, so you can find diagnostic information, updated drivers, or any additional software you may need. Since they run from your flash drive, the portable browser won't leave anything behind (cookies, history, cache) on the machine where you run it. You can also customize the portable version with your bookmarks and extensions.

#10 -- In a similar vein, if Microsoft Word is totally hosed (or no office suite is installed) the portable Libre Office word processor will do very nicely as a substitute. It has all the important features you'd expect to find in a word processor, and can read and write MS Word files..

Rescue Disks and the Reset Button

Sometimes a virus infection or other problem prevents you from booting directly from a system's hard drive. In these cases, you need a bootable recovery/rescue tool on a CD or USB drive. AVG offers a free rescue kit for downloading and disinfecting your system. Boot your system from the AVG Rescue CD, and it'll automatically scan your computer's hard drive for viruses and quarantine them.

For badly borked systems, you may be tempted to just hit a Reset Button and start from scratch. It's possible to restore your computer to that shiny just-out-of-the-box condition, but that's not something I recommend. See my article [RESET BUTTON] Restore Your PC To Factory Defaults? for details on that process.

I've never used Wise Registry Cleaner Free Portable edition. Is it better than the portable version of CCleaner? Otherwise, excellent list. Thank you very much for pulling them all together.

For some reason, when I tried to download any of the ZIP files, my Norton util prompts Run/Save/Cancel... I've hit 'Run' and windows goes crazy, flashing screen after screen and I have to turnoff my tower to get it to quit... and another bummer is when Explorer came back up,when I hit 'restore session' then windows kept flashing on my screen... Are we suppose to save the file(s) and extract them? Really slowing me down...

Thanks, Bob! Per Daniel, CCleaner works (I think) and has never crashed my computer. How about Glary Utilities or toni-arts' Easy Cleaner? Similarly, no crashes, but each finds different trash cluttering the system.

Always have a file recovery program on your USB flash drive. I use Piriform's Recuva (http://www.piriform.com). Very useful!

Good list Bob. Would you consider a similar list for the Mac crowd which is hankering for the same info because we are not immune to bad stuff either.

Bob - Thanks for all these "recovery" programs. I am downloading to thumb drive as suggested. I have been looking for something like this which lists the programs I needed for repair and backup, and on a thumb drive yet.

It must be in the fine print: you can't install the disk defragmenter, apparently related to my having an encrypted hard disk...

These are mostly very useful tools. HOWEVER - Be aware the the Ultimate Disk Defragger is loaded with Crapware!! Even if you carefully opt out of everything you see, it still installs items you won't want, and some is very hard to get rid of. Be aware!

EDITOR'S NOTE: Not true, in my recent test. I downloaded the software from CNET, and although it took some care, I managed to opt out of all the "extras" that CNET wanted to foist on me.

Bob, I have a problem and I hope you can help. I have an XP system with Asus Motherboard and AMD Chip. Insalled WD 1Tb Caviar Black Hd in a removeable enclosure. After installing everything was fine. Wrote a coouple of backups to it and all was still fine. Removed the drive shut down the computer and then put the drive back in and all was still fine. I decided to change the drive letters with the tools in XP and everything seemed fine. I shut down the computer and removed the drive. I reinstalled the drive and the system will not recognize the drive. Bios knows it is there but XP does not. WD Data Lifegard does not find it either. Any ideas as to what I might do to correct the problem.

EDITOR'S NOTE: Does switching the drive letters back to the original fix the problem?

SpyBot Search and Destroy must be given "Run as Administrator" permission on Win 7 Computers, or it won't do a proper job of fixing spyware.

Right click on the Icon, select properties, hit the 'Advanced' button, select "Run as Administrator"

Spybot may be old and funky but it FINDS and cleans things others won't!

Tool #11: Microsoft Windows Profiler... "bootvis"
Reboots windows number of times to optimise the boot up sequence of startup services and .DLL files.

Tool #12: Sysinternals Pagefile defrag.
The tool that noone ever uses, and should.

Hi. You should check out some of the greatest tools for computer techs to use in fixing almost any problem with a computer:
* D7 - one of the most comprehensive tools available & even works on systems that are "offline" (ie, boot from USB)
* Falcon4Boot Disk for Windows - a highly customized "pre-boot" or pebuilt version of Windows that uses "mini-XP" to boot yoru computer from a flash drive
* Hirens Boot Disk - much the same as Falcon4.

Note for anyone using ClamWin Portable:

Be sure to run the program after you first download it (on a system with an internet connection) as the program needs to check for updates and download a datafile with up-to-date malware info. The basic download does not include any signature database files and won't run without one. You'll need to update ClamWin's database files on a regular basis just like any other anti-virus program.
