Errors 0xC1900101 0x2000C while updating from 8 to 8.1 on Win-Store

Hi,

This is caused by a driver bug check during image apply. 

1)       What is the make and model of the computer?

2)       Do you have any external devices (except the mouse and the keyboard) connected to the computer?

3)       Are you using any third party security program installed on the computer?

You may try the following methods and check if that helps.

Method 1: Disconnect all the unnecessary external devices connected to the computer (except the mouse and the keyboard)

Please disconnect all the unnecessary external devices connected to the computer (except the mouse and the keyboard) and then check if you still face this issue while installing Windows 8.1. This is to check if the issue is caused by any external devices connected to the computer.

You may also try installing all the driver updates for all the devices installed on the computer and check if that resolves the issue. You may try the next methods and let’s know the result.

Method 2: Update the Device Drivers on the Computer.

Step 1: Check the Windows updates for any latest driver updates.

Check in Windows updates if any driver updates are available. If so, install the same and check if it helps.

a)       Press “Windows Logo” + “W” keys from the keyboard.

b)       Type “Updates” in the search bar and click on “Install optional updates” from the left pane.

c)       From the “Windows Update” window, click on “Check for Updates” on the top left corner, to receive a fresh list of updates and then install all the updates listed there.

Hi Vijay,

I too have the same issue. I have deactivated the antivirus, Updated all my drivers, no external usb is attached to it, uninstalled all the softwares that may cause the issue but no use.

I have an HP-Pavilion G6-2005AX laptop with AMD A-8 APU

Kindly Help.

P.S: I have downloaded the update twice but no use.

Kindly help.

Hi,

thanks for support. I had no external devices connected, all softwares are up to date. I have also removed antivirus software but still the same errors. I give up! My laptop is a VAIO: i7, 6 GB RAM, 256 SSD, I think the hardware is okay. Have to be happy with the 8 :(

I an having the same problems on my Toshiba laptop. It came installed with widows 7 and I upgraded it to 8 on day 1. Now I want to get 8.1 but I am experiencing this problem. I updated a few of my drivers but to no success. I will try to update the rest. Anyone know of an easy fix?

It was pre-warned that Windows previous versions would need to be re-installed, then Windows 8 and then upgrade to Windows 8.1.

You might try putting the system in clean boot and retry installing the update.

Or,

You could always use the Upgrade Assistant and create an .ISO file which may be used to install it.
