Since I have installed win7, by default automaticcaly windows update till date. Now before formatting my PC, I want to make boot DVD with all till date updates. How Can I?
If I understand the translation correctly you are wanting to create an image of your system including all updates which you can then use a bootable disk to recover from. Acronis True Image allows you to create bootable rescue media and also burn a complete image of a drive which you can then recover using the bootable disk.
