Method #2.1: Performing a System Restore.

Force restart, by long pressing the power button.
Just when you see manufacturer logo hit F8 or F2 key (depends on the machine you are using) to enter BIOS setup.
There are a number of ways to enter Advanced startup options but in this situation having windows 10 installation USB or DVD will be pretty helpful. (or you could choose to boot your PC from recovery drive if you have created one on your PC)
Select language, and click Next.
Click on Repair your computer in the bottom-left.
In next window, choose the Troubleshoot option.
On this screen, select Advanced option.

Method #2.2: Delete Update Files via CMD.

When the System is unable to create any restore points, the above method fails.

Follow Steps 1 to 7 depicted in Method #2.1.
As the 8th step, On the Advanced options screen, click Command Prompt instead of system recovery.
A command prompt window will appear. Type in these following commands in a sequential manner and hit Enter after each one of them:
a) cd C:Windows
b) del C:WindowsSoftwareDistribution*.* /s /q
Close the Command prompt window
Restart your PC.
As a result, you will be able to log on to Windows normally trapping yourself in the loop.
Finally, try re-installing the update and maybe this time you get rid of “we couldn’t complete the updates, Undoing changes” error message.

Method #2.3: Disable Secure Boot.

Disabling secure boot is one of the methods if the above doesn’t work for you. Steps to disable Secure Boot:

Firstly, enter into BIOS setup, same as in step 1 and 2 of Method #2.1.
Navigate to Secure Boot setting (You are likely to find this setting usually in either the Security tab, or Authentication tab, or the Boot tab .), toggle it to Disabled.

Important: After disabling Secure Boot, enabling it again is hard without restoring your PC to the factory state.
Finally, Restart your PC.
Consequently, updates will be installed successfully without any error message like “we couldn’t complete the updates, Undoing changes.”
After the whole process, don’t forget to Enable the Secure Boot option from BIOS setup.

Miscellaneous Methods

Try freeing up some space on computer hard drive to accommodate the update by either deleting some useless data or by increasing the system reserved partition.
Also, try Disabling Windows firewall and antivirus, then again try re-installing the updates.
Run SFC and DISM
