Windows 7 upgrades fail because of Intel driver

The best laid plans of mice and voles

MICROSOFT MUST BE FURIOUS after software upgrades from Vista to Windows 7 failed on some machines because they had an Intel storage driver.
For months before the launch the Vole worked with hardware makers to make sure that drivers working under Windows 7. It wanted to avoid a repeat of the Windows Vista fiasco, which was caused by the operating system shipping with too few working hardware drivers.
Most of the time this worked however according to Microsoft, there are users that experienced failures when upgrading from Vista to Windows 7 because of an Intel storage driver.
When people try to upgrade they get a an error messsage: "\$windows.~bt\windows\system32\drivers\iastor.sys. Status: 0xc0000359. Windows failed to load because a critical system driver is missing or corrupt."
The machine would subsequently be rolled back to Vista and after a while the user would want to throw something out of the Window.
What is causing the fault are incorrect versions of the iastor file that are referenced during the move to Windows 7. Microsoft hasn't produced an update or hotfix designed to resolve this particular issue yet.
Users have to manually fix the problem using a fairly complex upgrade which will require some fairly brave person to try.
The Vole tells us to:
"1. Access Driver Repository Folder under C:\Windows\System32\DriverStore\FileRepository and move any folders that contain the file: iastor.inf to a temporary location.
2. Search for references to iastor within the oem inf files in the c:\windows\inf folder - Example Command: findstr /i /c:"iastor" %windir%/inf/oem*.inf.
3. Make a note of the oem##.inf files reported where ## is a numeral. Move the oem##.inf and corresponding oem##.pnf from c:\windows\inf folder to a temporary folder.
4. Delete $~bt, $~LS and $~Upgrade folders from c:\ drive if they exist
5. Download and install the latest version of the iastor.sys driver from Intel website on the Vista machine.
6. Start the Windows 7 upgrade process. It should complete successfully now."
Yikes. Hopefully there will be a patch soon. It is not clear how many people are affected by the bug. We guess we will hear all about it soon. µ
