When you backup your system using this technique the system is backed up in a crash-consistent state. When you restore from the backup it’s like someone yanked the power cord out of your computer at the time you started the backup. The file system used in Windows Vista Home (NTFS) can cope with that so for the most part your files will be ok but some programs may not (e.g. they might have been halfway through writing a file).
It’s also important to note that robocopy does not copy NTFS junction points. This is normally harmless but it can stop some older, poorly written programs from working.

You can schedule the backup script to run on a regular basis, e.g. once a week.

Firstly, if you do not have the Windows Vista Setup CD:
How to restore your system onto a new hard disk (in the event your old one dies).

vshadow.exe and dosdev.exe to that directory.backup.cmd with the following contents:robocopy is included with Windows Vista Service Pack 1- older versions won’t work.
Vista Service Pack 1 may be downloaded from here: http://technet.microsoft.com/en-us/windowsvista/bb738089.aspx
vshadow is included in the Microsoft SDK
The Microsoft SDK may be downloaded from here: http://www.microsoft.com/downloads/details.aspx?FamilyId=E6E1C3DF-A74F-4207-8586-711EBE331CDC&displaylang=en. You need to install at least the Win32 Development Tools. vshadow.exe may be found in C:\Program Files\Microsoft SDKs\Windows\v6.1\Bin\vsstools.
You also need another program, dosdev, which allows you to mount a Volume Shadow Copy as a normal drive with a drive letter.
dosdev may be found in Microsoft Product Support’s Reporting Tools, specifically MPSRPT_CLUSTER.EXE. That file may be downloaded from here: http://www.microsoft.com/downloads/details.aspx?familyid=cebf3c7c-7ca5-408f-88b7-f9c79b7306c0&displaylang=en. Do not run MPSRPT_CLUSTER.EXE when you download it. Instead open the file with 7-zip and extract dosdev.exe.
Windows Vista Home doesn’t come with the Complete PC Backup feature found in the Business and Ultimate editions.
The good news is you can use some freely available Microsoft tools to perform regular scheduled backups of your complete PC that can be restored onto ‘bare metal’ (e.g. a new hard disk to replace one that failed).
The backups are performed using two programs:
vshadow - performs a Volume Shadow Copy (or snapshot) of your hard disk
robocopy - “Robust File Copy”
The vshadow command takes a snapshot of your hard disk. The snapshot includes files that would not normally be accessible by programs, such as registry hives.
The robocopy command can be used to copy files from the snapshot to a backup directory (e.g. on an external hard disk). The options passed to robocopy ensure that metadata such as security descriptors and file times are copied along with the files.

I upgraded my new PC from Windows XP to Windows Vista. After doing so I noticed the PC would intermittently hang. The hard disk light would stay lit for a while then go out, then the computer would resume. In the System Event Log I found this message:
The device, \Device\Ide\iaStor0, did not respond within the timeout period.
Searching on Google I found this article on Intel’s website:
http://www.intel.com/support/chipsets/imsm/sb/cs-025783.htm
The article suggests upgrading to the latest version of the Intel Matrix Storage Manager drivers should solve the problem. It didn’t. However I noticed this paragraph in the article:
Because the setup change means that LPM is enabled by default for all Windows Vista platforms, using a device that does not completely follow the specification may result in one of the listed issues.
I found the registry settings for the iaStor and iaStorV drivers at:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStor\Parameters
and
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\iaStorV\Parameters
Then for each port (Port0, Port1, etc.) I changed the LPM and LPMDSTATE values from 1 to 0. This solved the problem.
nxtasy.org has an article about making your NXT speak. This prompted me to finish off a small program I had lying around.
Presenting: nxtsay. Simply pass the program a message you want your NXT to say and it will do so. Or alternatively you can give it a file to read out.
Here’s the synopsis:
Speaks the given text on a Lego Mindstorms NXT. NXTSAY [/Q] [/T:timeout] [message] NXTSAY [/Q] [/T:timeout] [/F] filename If the message is not supplied it will be read from STDIN. /F Read message from the given filename. /Q Don't print any output. /T:timeout Specify the time to spend searching for a NXT. /V:volume Specify the volume of the speech (%).
You will need the Lego Mindstorms NXT software installed. The program should run ok on Windows XP and Vista - let me know if you have any problems!
