The upgrade will not set up and attempting once again tosses the exact same mistake message once again.

The mistake code 0x80070643 validates the concern. Microsoft released an assistance short article that validates the concern and offers some description. According to Microsoft, the upgrade is resolving a security vulnerability that might enable opponents to bypass Bitlocker file encryption by utilizing the Windows Healing Environment (WinRE).

The concern that makes Windows PCs toss the mistake code is that the healing partition is not big enough to finish the upgrade. Administrators might likewise get the mistake message “Windows Healing Environment maintenance stopped working. (CBS_E_INSUFFICIENT_DISK_SPACE)” when they attempt to install it.

Update: before you make any modifications to the healing partition, attempt rebooting as soon as to see if this deals with the concern.

Open Start, type CMD, and choose “run as administrator” to introduce a raised command trigger window.
Run the command reagentc/ details If you see course info, WinRE is allowed. Keep in mind the number behind harddisk and partition in the course, these are required later.
Run reagentc/ disable to disable WinRE for the operation.

Now diminish the OS partition to produce a brand-new healing partition:

Run diskpart
Run list disk to get a list of all hard drives linked to the computer system.
To choose the os disk, run the command sel disk << OS disk index>> Change >> OS disk index” with the harddisk worth.
List all partitions by running list part Look for the main partition there. It is normally the biggest.
Select the (main) os partition with the command sel part << OS partition index>>
Run diminish preferred= 250 minimum= 250. This diminishes the os partition by 250 MB.
Run sel part << WinRE partition index>> to choose the healing partition. Utilize the partition number that you got when you ran the very first command at the top.
Erase the partition by running erase partition override
Type list disk once again and examine if there is an asterisk character
1. in the GPT column of the drive.
  1. If the disk with Windows on it is GPT, run the following commands:
  2. produce partition main id= de94bba4-06d1-4d40-a16a-bfd50179d6ac
2. gpt associates =0x8000000000000001
  1. If the disk is MBR, run the following command:
produce partition main id= 27 To format the partition, run the command format fast fs= ntfs label=” Windows RE tools”
Run the command list vol
to validate that the Healing Partition is offered once again.
Type exit to leave diskpart. Run reagentc/ allow
to allow the healing environment once again. Ensure that this holds true by running reagentc/ details
