Despite the fact that the $119.48 upgrade offer for the forthcoming Windows 7 operating system, scheduled for launch October 22, may sound rather economical one, most technology experts are cautioning the users about the high-tech upgrading process, which apparently is far from easy!

Noting that the upgrade can be a vexing experience, tech gurus far and wide have expressed the opinion that the high-tech mire of the upgrading process may practically be fairly difficult to run through, even the most so-called tech-savvy users.

For users with certain systems, the upgrade may best be avoided as the process would require them to perform a "clean install," which means that it would include a wipe clean of the hard drive clean and a start from the scratch.

Walt Mossberg, a renowned technology specialist at the Wall Street Journal, has offered a word of caution for the potential upgrade enthusiasts, in his column titled "For Some, Move To Windows 7 Will Be Tough."

According to Mossberg, the upgrade process "will be anything but simple for the huge base of average consumers still using XP, who likely outnumber Vista users. It will be frustrating, tedious and labor-intensive."

Further referring to the 'not so appealing' upgrade figures, Mossberg added that an "official" chart has revealed that only 14 of 66 possible upgrades could be completed with an in-place upgrade rather than a clean install.
