The skinny: Untangle for Windows is a free way to protect your home/small office network (up to 10 computers). It leverages open source software to give you advanced control of your network that until recently was only affordable to larger corporations. Its features are impressive, especially for a free download.

Unified Threat Management (UTM) software is a fancy name for a collection of dedicated software (or a hardware appliance) that work together to protect a network by providing for example, virus protection and web filtering.

Years ago, UTMs were only available as hardware appliances which were installed in a server rack in a data center. More recently, software UTMs were released by companies like Endian and Astaro and Untangle that can run on PCs. These software UTMs require a dedicated computer. (more…)

 

If you’re like us, maintaining your laptop/notebook/netbook’s battery is about as high on your priority list as cleaning out leaves from your house’s gutters. You know it needs to be done, but…

It seems that the best utilities do one thing and do it well. BatteryCare is one of those. Basically it aims to maximize your battery’s life by tracking the discharges (i.e. letting the battery charge drop from 100% to 3%), and prompting you to recalibrate after 30 discharges. (more…)

MyDefrag version 4.1 is a hard disk defragmenter and optimizer. If it looks familiar, that’s because it was previously called jkDefrag, which we covered last year. Because it uses the same API (application programmer interface) built into Windows that Microsoft’s own Disk Defragmenter uses it is safe to use. Unlike Microsoft’s utility, MyDefrag works much more quickly.

One reason for MyDefrag’s effectiveness is that it moves files to the physical “start” of a hard drive. Accessing files from this area of a hard drive is up to 200% faster than from other areas.

There are as many utilities for bypassing Windows (and Linux) login passwords as there are legitimate reasons for doing so (you ARE only using your powers for good, right?).

Kon-Boot can help you to bypass a login password. It can be run from a boot CD, floppy, and (thanks to Irongeek), from a USB flash drive.

Need to help a friend (or yourself) to overcome a password-protected Windows or Linux computer? Check out Kon-Boot.

 

SpinRite 6.0 Might Make You a Hero

SpinRite 6.0 from Gibson Research Corporation (GRC) is not new (released in 2004) nor is it free (USD$89), but it can fix hard disks (or even floppy disks!) that appear to be beyond recovery. Depending on the condition of the drive, SpinRite could recover files that could otherwise cost thousands of dollars if you were to hire a professional data recovery firm to do the job.

It works by interacting directly with the magnetic media, fixing problems that occur as a result of normal use. You boot your computer from a SpinRite CD or floppy disk, then follow the menu prompts to perform maintenance or data recovery.

Why Would I Use It for Myself?
SpinRite is a good preventive maintenance tool for your hard drives, basically any drive except the newer solid-state drives. GRC recommends running SpinRite every 2 to 3 months. If it detects any bad sectors on a drive, it marks those sectors so that the operating system will not use those areas of the hard drive. This can keep your drive healthy, and for Windows XP users, can minimize the possibility of a “Blue Screen of Death” (or for Vista users, the blacK Screen of Death).

How Can I Use It To Help Others?
We know you back up your own data regularly (you do, right?) but when you get a call from your not-so-computer-savvy friend telling you their computer won’t boot, the data-recovery SpinRite could save the day. If a hard drive suffers serious trauma (such as being dropped), the possibility of recovering the drive is low. But, if the computer does not boot because of one or more bad sectors, SpinRite could have your friend’s computer back up and running in hours.

A Personal Note
A dear friend of ours had a Toshiba laptop that worked fine–until it refused to boot. The local computer technicians gave her the bad news: the hard drive was dead. Our friend was sad that she had lost hundreds of digital photos of fond memories of her travels, and her engagement party. She bought a desktop computer, but kept the laptop drive in a drawer for more than a year. When she told us what had happened, we asked to borrow her hard drive. First, we plugged the drive into an external USB case and tried to access it by plugging it in to another computer. The drive made some really bad noises, and we couldn’t access it at all. This drive had some serious problems!

Next, we put the drive in a laptop, booted into SpinRite, and within 3 hours, SpinRite had repaired 8 bad sectors. We rebooted the laptop (without SpinRite), and it booted into Windows! It was still making bad noises, so we quickly copied off the “Documents and Settings” folders (which included all of the digital photos). The copying process went well at first, but when it reached 97%, the “time left” climbed from 5 minutes to more than 3 hours. Eventually, we saw a message telling us the drive could not be read. Maybe the drive has officially died, but it survived long enough to copy off the important files.

We burned the files that we copied to DVDs and look forward to surprising our friend with some long-lost memories.

Takeaway: SpinRite 6.0 is a utility that anyone can use to maintain their hard drives, and has proven itself many times as a data recovery tool.

It’s rare that we recommend software that actually costs money, but if it can recover business-critical data (or priceless memories, as in our friend’s case), $89 dollars can be well worth it. Consider adding SpinRite 6.0 to your computer rescue kit.

 

AVG Antivirus 8.0’s recent set of antivirus definitions broke Windows XP by quarantining XP’s user32.dll as a bad file.

There are 2 ways to fix this:
Windows XP CD – If you have a Windows XP installation CD handy, follow these steps.

No Windows XP CD – Grisoft has created a bootable .ISO or bootable flashdrive image. Follow these steps to repair your PC. (Need to burn a CD from that .ISO? Use the free utility ImgBurn.)

 

Corporations have disaster recovery plans, and so should you. If you want to minimize your own computers’ downtime due to hard drive failure, operating system corruption (i.e. the “Blue Screen of Death”), and the like, there are a number of solutions that you can use that can help you get back up and running quickly.

New PC? Clean up the “Extras” with PC Decrapifier

Have you unboxed a brand new Windows computer and plugged it in, only to find a desktop full of “trial-ware” installed? Perhaps the browser’s home page has been hijacked redirected to the computer vendor’s website?

The situation is getting better. In early 2008, Sony began offering a “Fresh Start” option when you are purchasing a computer from their site, which lets you opt out of trial-ware. Initially they charged $50, but after a public backlash made this a free option.

Dell also lets you opt out of trialware (such as anti-virus, “productivity” software, etc). If you have an Inspiron or Dimension PC, check out the 3rd-party software-removal tool (Start > All Programs > Dell > Dell Software & Utilities > Product Documentation).

If your new computer does have these software applications preloaded, take a look at the free utility, PC Decrapifier. (more…)

 

Even with a decent-size screen, if you’re running many applications at the same time, it can be time-consuming toggling through all those windows using Alt-F4 or the taskbar. Wouldn’t things be easier if you have one screen just for email, another for word processing, another for editing graphics, etc.?

Enter Desktops 1.0

Mark Russinovich
and Bryce Cogswell recently released Sysinternals’ Desktop 1.0, which allows you to create up to 4 “virtual desktops.” A tiny (62 KB) download, you simply install it and run it. You can choose which key combinations you’ll use to switch between the virtual desktops.

Takeaway: Desktops 1.0 is a free and simple way to segregate whichever applications you’re currently running into their own virtual desktops.

It’s just one of many free utilities that Sysinternals offers. Many of these will give you insight into what’s happening “behind the scenes” of your Windows operating system. You might just find a utility here that you’ll use every day.

 

Turn .ISO Files into DVDs/CDs with ImgBurn

An .ISO file is an “image,” containing the complete contents of a CD or DVD. It’s a common way that versions of Linux (or many of its variants) are released. For example, you might want to download a copy of F-Secure Rescue CD 3.00 so you can scan a hard drive for any malware.

Also, if you create a BartPE .ISO file as we discussed earlier in “Backup Your Hard drive Now – While You Still Have Time,” you’ll need a way to turn the .ISO into a bootable CD.

If you have Nero or a similar program, you can burn that image to a CD or DVD. Alternatively, you can use the free utility ImgBurn to do the same thing. (more…)
