Microsoft released the first patch for Vista

Microsoft has just released its periodic security upgrade to patch 20 vulnerabilities, of which six are rated 'Critical'.

This upgrade also addresses the Windows Malware Protection Engine vulnerability in Windows Vista (a component that supports Windows Defender and OneCare). According to Microsoft, hackers can exploit this vulnerability to attack remote control hijacking.

Microsoft also introduced a new version of DRM technology

At the same time with the release of these patches, Microsoft also introduced a new version of DRM - Digital Right Management technology called PlayRead. This software is exclusively for handheld devices, enabling users to transfer the content they buy through the internet from a computer to other devices.

Experts say that Microsoft launched PlayReady just to compete with Apple, which is also using a similar software called FairPlay.

While the entertainment industry is quite happy, the virtual community, on the other hand, is very dissatisfied with this. According to many bloggers from websites specializing in technology, PlayReady not only does not help as advertised but also makes users unable to view the content they want because it does not support 'old' devices.

Vince Veneziani, a blogger at CrunchGear, said: ' We were tired of it. Obviously this must end . '

Earlier a week, Apple chairman Steve Jobs also called for a halt to the use of DRM technology in the digital music business. Mr Jobs said the technology limits sales of today's digital music industry.
