Method 2: Use Diskpart to Create a Larger Recovery Partition

Aside from utilizing a professional partition resizer, Microsoft has published a guide that teaches users how to shrink the C: drive by 250 MB and create a new recovery partition using the reagentc.exe and diskpart command lines, allowing for WinRE security updates. It's worth noting that this approach demands users to be proficient in operating command lines. If you are a beginner, I strongly advise you to try the first method. Please refer to the step-by-step instructions provided by Microsoft Support:

Step 1. Open the Command Prompt, run it as an administrator, and type the following commands (press "Enter" after each one to confirm the action):

• reagentc /info (check the status of the Windows Recovery Environment)
• reagentc /disable (disable the Windows Recovery Environment before the process)

Step 2. Run the diskpart tool to shrink the OS partition for creating a new recovery partition and delete the old one. Enter the following command lines (press "Enter" after each command):

• 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 beginning, you need to check whether your disk partition is GPT or MBR by running the following commands:

• list disk (GPT disks will display an asterisk character in the GPT column)

如果您的磁盘是 GPT 格式：

Translate the following text into English:
• Create partition primary id=de94bba4-06d1-4d40-a16a-bfd50179d6ac
• GPT attributes =0x8000000000000001

如果您的磁盘是MBR：

• create partition primary id=27
• format quick fs=ntfs label="Windows RE tools"
• list vol
• exit
• reagentc /enable (enable WinRE)
• reagentc /info (confirm the WinRE is enabled)
