Ok thanks, I will follow your advice. Do you think that a repair install will definitely fix this? What was the cause behind the registry corruption so that I can prevent it next time?
Also will I need to backup any data files before I do the repair install?
Thanks again for all your help.
This type of this can be caused by disk failure, or by power failure during a read/write of the file involved.
It can also be caused by injudicious use of so-called registry cleaners.
A repair install should certainly fix it.
I tried to do a repair install and it didn't seem to make any difference.
After repeating the process a couple more times, it seems like after the upgrade is done, it tries to restart the computer but then I encounter a BSOD DRIVER_POWER_STATE_FAILURE, after which Windows tries to revert back to the original Windows version.
Anyone know what causes this BSOD?
Here's an article on it - Bug Check 0x9F: DRIVER_POWER_STATE_FAILURE (Windows Debuggers)
Because you're getting the error only under specific circumstances, I suspect that the problem is a bad driver somewhere - open Device Manager and check to see if any devices are disabled/flagged with either yellow warning triangles or red crosses
If they are, uninstall the driver involved.
Ok, the only icon that had a "!" mark on it was my mouse driver. I updated it and the "!" is no longer there.
Now I have another question. During the upgrade/repair install, I came across this message:
Could these 3 drivers also be causing the BSOD? The thing is I don't see any of these drivers listed under Device Manager and these are old peripherals that I no longer use (well except for maybe the Storage Controller). Are there any way to remove these drivers manually and safely?
Thanks.
If you open Device Manager, and click on the View option in the Menu bar, tick the Show Hidden Devices entry in the dropdown.
See if the devices appear there now - if so, uninstall them, and see if that helps.
I tried hitting Show Hidden Devices but it doesn't show up either.
For example, I was looking for "NETGEAR WG111v3 Wireless-G USB Adapter" under the Network Adapters menu and it wasn't in the list. Maybe the Windows Setup is just blindly scanning a bunch of dll files instead?
