Hi Rajesh,
I am having the same issues when trying to upgrade to Windows 8.1. I thought I would list my system specs, and steps I have taken to try and resolve the issue, as everything I have tried will still not work.
Couldn't update to Windows 8.1 - 0xC1900101 - 0x40017
System:
Gigabyte X79-UD3 rev 1.0
Intel Core I7 3930K CPU
Nvidia GTX 560 Ti
16 Gig Ram
OCZ Vertex 3 120Gig
Compro Video Mate E900F TV tuner card
Microsoft Wireless Mouse & Keyboard
Windows 8 Pro with Media Centre - 64bit
Steps taken:
Deleted all files in all "temp" folders.
Ran Virus and Spyware checks - all clean. ( using Windows Antivirus ).
Updated the bios to F16 which is the latest.
Unplugged all external devices, and updated all drivers to the latest versions.
Put all the Windows updates in, and the optional updates.
Removed the Compro Videomate TV card, and uninstalled the driver.
Have also tried a "clean boot", with nothing loaded and removed all not needed programs.
Deleted the contents of the "softwaredistribution" folder, to start with a new 8.1 upgrade download.
The system had originally been a clean install of Windows 7 Ultimate, and then I applied the Windows 8 Pro upgrade. I was then offered the upgrade with Media Centre which all installed fine, and I am not running any third party security software ( only
Windows Defender/Firewall). When I first did the upgrade from Windows 7 to Windows 8 pro, I had a lot of issues with trying to get it to boot with "AHCI" enabled in the bios. I had to go through a few registry edits to finally get it to boot, and it has
been running ok. I don't know what else to try, as I have pulled the system down to just a graphics card, hard drive, mouse & keyboard. Maybe is has something to do with the registry edits?
Hoping you may find what the issue is in what I have described above.
Thank-you
Cameron.
