Many users complain that they cannot upgrade from the current Windows Vista to Windows 7, and the culprit is actually Intel's storage driver.
Microsoft has confirmed this, saying the problem lies with Intel's storage driver. When users upgrade from Vista to Windows 7, the system will prompt that key system drivers are missing or damaged. The system will then roll back to Vista.
At present, Microsoft has not released a corresponding patch, but only provides a complex solution that requires users to perform at least 6 steps of complex operations.
As Microsoft's closest partner, Intel should not have this problem, and I believe Microsoft will also be angry. In the months leading up to the launch of Windows 7, Microsoft has been working closely with hardware manufacturers to do its best to ensure driver compatibility.
