Seems finally the wait is over for those users who are die-heartedly waiting for Windows 8.1 as the company today made the update available now for downloads. The new update means a user will get the number of improvements, including built-in Bing search, SkyDrive syncing and more. For updating, if you are an existing Windows 8 user, then moving to Windows 8.1 is easier while it will be good to keep a backup of everything. On the other hand, if you are upgrading from Windows 7, then you need to buy the Windows 8 upgrade option ($119 or $199 for Windows 8 Pro) and then you too can make the upgrade.
