Microsoft released security update KB5034441 for Windows 10 during the January 2024 Patch Tuesday event, focusing on fixing vulnerability tracking number CVE-2024-20666, which can bypass BitLocker encryption and access encrypted data. However, many Windows 10 users report that an error of 0x80070643 = CBS_E_INSUFFICIENT_DISK_SPACE(Windows recovery environment servicing failed.) may occur during the installation of KB5034441.

Create a complete backup for your recovery partition or the whole system disk in case any unexpected error occurs.
EaseUS Partition Master Professional empowers you to create, resize, merge, and split partitions. With this tool, you can enhance the control over disk space by enabling partition resizing and relocation. Its "Resize/move" and "allocate space" can help users extend the recovery partition and make room for the update KB5034441.

Beyond using a professional partition resizer, Microsoft released a guide to teaching users to shrink the C: partition by 250 MB and create a new recovery partition using the reagentc.exe and dispart command lines, which can accommodate WinRE security updates. Notice that this solution requires users to be proficient in operating command lines. If you are a beginner, I highly recommend you try the first method. Refer to the step-by-step instructions provided by the Microsoft Support:
Step 1. Launch the Command Prompt, run it as administrator, and type the following cmd(press "Enter" each time to confirm the action):
- reagentc /info (check the WinRE status)
- reagentc /disable (disable the WinRE before the process)
Step 2. Run diskpart to shrink the OS partition for a new recovery partition and delete the old one. Input the command lines (press "Enter" for each cmd):
- list disk
- sel disk(which is the same disk index as WinRE)
- list part
- sel part
- shrink desired=250 minimum=250
- sel part
- delete partition override
Step 3. Create a new recovery partition. Before starting, you need to check if your disk partition is GPT or MBR by running the commands:
- list disk (GPT disk will show an asterisk character in the GPT column)
If your disk is GPT:
- create partition primary id=de94bba4-06d1-4d40-a16a-bfd50179d6ac
- gpt attributes =0x8000000000000001
If your disk is MBR:
- create partition primary id=27
- format quick fs=ntfs label="Windows RE tools"
- list vol
- reagentc /enablem (enable WinRE)
- reagentc /info (confirm the WinRE is enabled)
