A school in the USA issued their students laptops with webcams built in, which sounds a nice plan since students could use them to talk to their friends, only the school officials could also see what the students and their families were up to covertly.

There is a class action lawsuit against the school because of this invasion of privacy.

Microsoft has discovered after a in-depth investigation that a rootkit called Alureon was the cause of the reboot loop problem after installing several patches.

Rootkits are programs that replace system files to prevent an antivirus discovering what they are doing as well as provide trojan horses a chance to run programs without the users knowledge. A rootkit can cause a computer to send out spam emails.

Rootkits can be very difficult to discover and remove and in some cases it is easier reinstalling the computer from the CD than to remove the rootkit as too many program components may be damaged.

Windows 7 has introduced a feature called HomeGroup that helps connect two Windows 7 computers together. The 'host' machine creates a unique pass phrase that must be typed into the 'client' machine in order for the two machines to talk to each other.

You have probably sent a word document to a friend only to find they can't open the file since you have sent it with Office 2007 and they have an older version. 

1. Go to the flag in the circle and click. You will see two options on the bottom right of the menu.
2. Click on Word Options. 
3. On the left side, click on Save
4. On the right side, change the drop down box to WORD 97-2003 .doc
5. Click OK

Now whenever you save files in Word, you will save them in a format that people with older versions can open them.

The same goes for Excel and Powerpoint.

This is something I learnt the hard way after reinstalling a Windows 7 laptop. Windows 7 has issues when it comes to permissions on files and folders shared with Windows XP.
