Ever been unable to log into Windows due to a lost password? This used to require a reinstall of the operating system to regain access. This often meant some data would be lost, as it could no longer be accessed.

Because of this common need to recover passwords, a few tools have been created to get past this problem. I once heard of a program called Ophcrack, but it looked a bit tricky to use.

A tool called PC Login Now was recently made available as freeware, so I tried it out. The download is an iso file that needs to be burnt to a CD, using just about any CD burning software. The result is a Linux Live CD. Restart your computer and ensure that the computer will boot from your CD drive first (most will by default). Watch the Linux Live CD boot to life.

PC Login Now will work with any Windows install, and it can even handle dual boot machines. The opening screen shows you the operating systems available on the computer. Select the operating system you want to tinker with and press next. You should now be able to see all of the user accounts for that system.

You can then reset the password of any account, as well as enable or disable accounts. You can pretty much perform any of the basic user account options available in Windows. This program does not show you the old password as some tools do, but resetting the password is just as useful in most circumstances.

Once your computer reboots, a disk check will be run. When prompted, try to login leaving the password blank. You should be able to get into the system. PC Login Now claims a 100% success rate, and so far I have had no failures on the 3 machines I have tested. It couldn’t be quicker or easier to use.

This will not work for computers which login to a domain, but there is normally a local user account on these computers, which you can use to gain access.

Take some caution using this in the workplace as many companies don’t like these tools.

PC Login Now 2.0 is available for free from pcloginnow.com.

In Windows, each file has an extension in its filename which is used to identify which program will open the file, and which icon should be attached to that file. These can be changed fairly easily from within “folder options”, but the interface is not all that user friendly.

Types is a worthwhile replacement to the inbuilt Windows file type utility. It works on both Windows XP and Vista. It also offers a large display window so that you can easily find the extension you want tinker with.

To use Types, right click on the extension you want to edit and select properties. From the window that opens, you are able to change which program will open up the file, the extensions icon, and a few class options, but you shouldn’t need to worry about those.

This program does a small job well, and it is an improvement on the inbuilt Windows options.

Types is available for free from SourceForge.

When a computer starts up and boots into Windows, there are a bundle of other programs that load up with it. Some of them are needed, but others are unnecessary and do little more than slow down a computer.

When I am told that a computer is running slow, the first thing I do is look in the locations that call these programs to load, and I cull the programs that are not necessary. There are numerous locations (registry, startup folders and win.ini) where these programs are called from, so the process can take quite a while.

Startup Manager is a free utility that shows you each of these locations in a single, easy to use interface. Just check out the screenshot of it. This is certainly a no nonsense program.

Startup Manager shows you what is going to be loaded at startup. All you need to do is untick the items that you no longer want to be part of your daily life.

The startup programs should probably be checked every 6 or so months to keep your computer running lean. The list can expand very quickly, often without the users knowledge. Using this utility can save a lot of time. It is one of those useful programs to keep on a USB disk, so that you can load it up quickly in the case a friend is in need.

Most spy-ware, trojans, viruses or spam ridden software will place entries into your registry, without your knowledge. Once the entry has been made, the program can run once the computer is restarted. If software is discovered after this, it is too late because the damage has already been done. A timely and difficult clean up job is required to restore your computer to full working order… if you are lucky.

Reg-runner is a program that runs in the task tray, that will help you protect your computer from these nasties, by popping up a small alert when a change is made to the registry, or when a program or process has started or ended. The majority of these alerts will be for programs you intended to install or run, but eventually the time will come when you are alerted to a program that is not wanted. 

Reg-runner has a number of tabs, showing the programs that are loaded at startup, running processes and registry changes. Each of these entries can be looked at more deeply. Right clicking on any of the startup items or processes will bring up a context menu. From this menu, Reg-runner can shoot you off to Google or Processlibrary.com for more information. Using these resources, you can find out if any program is malicious, or more simply, what any of your programs or processes do.

This program is small, weighing in just under 400k. For those who don’t like to use virus scanners or anti spy-ware programs because they slow down your computer, this would be a very sensible addition to the task tray.

Reg-runner is available for free from SourceForge. There is a standard version, and a black edition for those who like to live on the dark-side.

Last week we looked at NTFS Undelete, which is a great free program to undelete deleted files. As I tested it, I was able to recover many deleted files, some of which had been deleted for years. It raised a security concern for me that these files were so easily recovered, so I had a look for some programs that would help to make deleted files stay deleted.

Normally it does not matter if files are recoverable. It is handy in many cases. If a file is accidentally deleted, it is nice to know that all is not lost. Some sensitive files, you may want out of your life forever.

I came across a small but powerful utility called Eraser that would fulfill my needs. After running it, my deleted files were no longer recoverable. It can be used in two main ways.

First off is the Recycle Bin add-in. When you right click on the Recycle Bin, you normally get the option to empty it. Eraser adds a number of extra options for you. You can securely delete the files in the recycle bin using any of the extra options. Most of them will run several passes over the file. Others will replace the file with random data, which in both cases will ensure the file is gone forever. This does take longer than a normal bin empty, but it is not an uncomfortable wait.

Secondly, Internet history, cookies and uninstalled programs all bypass the recycle bin. That is why Eraser offers another component to look after you. Eraser can be setup to do a number of tasks on a schedule. You can delete files, folders… or my favourite, erase all free space. This ensures that any deleted files will remain deleted.

Lastly, many people sell their computers without correctly wiping the disk beforehand. This makes all of their data available to the purchaser, whether the files have been deleted or not. Using Boot and Nuke which incorporates Eraser, you are able to make a floppy disk or CD that will erase a computer completely before it is sold.

Eraser runs on most versions of Windows. Get your copy of Eraser for free from their website.
