Microsoft Office suite comes with some annoying features such as automatic capitalization of the first letter of the first word each time you end the sentence with a period. Many of these features are helpful but at times when you copy text from Microsoft Word and paste in somewhere else the formatting will be lost because it does not recognize Microsoft Office Word format. Same will happen if you are using Access, Excel, OneNote, Outlook, PowerPoint, Project or Publisher.
To avoid this, it is helpful to turn off auto correction feature in Microsoft Office.
If you are using Microsoft Office 2000 or 2003 version, you can turn of the automatic correction features by going to Tools -> Auto-Correction -> Deselect the features you want turned off.

If you are using the latest Microsoft Office 2007, you can turn off auto correction features by clicking on the Microsoft Office Button and then selecting Word Options. Note: If you want to turn off auto correction for other office programs such as PowerPoint then you would follow the same procedures but you will see PowerPoint Options.

Click Proofing and select AutoCorrect Options.

Now deselect the options you want disabled.
Copies of Microsoft Office Word sold between 2000 through 2006 are infected with a contemporary security flaw which allows malicious hackers to seize control of users’ PCs through an email with a Word document attached.
On Tuesday, Microsoft Corp. issued a security advisory about the possible threat. Security “advisory” is considered less urgent threat compared to other security notification but the attacks are being investigated by the company.
Microsoft Office Word 2007, currently designed for businesses, is not exposed to malicious attacks. The company has not released a patch to address the problem as of Wednesday. A user can be a victim if he or she opens a Word document attachment in the e-mail. It is recommended that users refrain from opening or saving unknown attachments, even if it is from a friend.
