Microsoft Office XP (Office 10.0 or Office 2002) was released in conjunction with Windows XP, and was a major upgrade with numerous enhancements and changes over Office 2000. Office XP introduced the Safe Mode feature, which allows applications such as Outlook to boot when it might otherwise fail by bypassing a corrupted registry or a faulty add-in. Smart tag is a technology introduced with Office XP in Word and Excel and discontinued in Office 2010. Office XP includes integrated voice command and text dictation capabilities, as well as handwriting recognition. It was the first version to require Microsoft Product Activation worldwide and in all editions as an anti-piracy measure, which attracted widespread controversy. Product Activation remained absent from Office for Mac releases until it was introduced in Office 2011 for Mac.
