I was updating my Lab, and came to this little issue I would like to share with y’all.
I was applying the patch for KB4696 to ensure my 12.3 was fully patched, but then I noticed my free space on the C drive was insufficient.
First thought: easy… let's enlarge the drive (it's virtual), increase it, and continue…
The recovery partition didn't allow me to do so.
Find below the screenshot of the patch installation + steps for being able to extend your drive in case you also need to.














Let's fix this issue to be able to deploy the patch,
As you can imagine, we will shut down the VM, reboot, and then relaunch the install and continue.

Here's a breakdown of the methods:
Using Disk Management and Diskpart (Requires disabling and potentially deleting the recovery partition):
Disable the Recovery Partition:
Open an elevated command prompt and run reagentc /disable. This moves the recovery partition's functionality into a file (Winre.wim).
Delete the Recovery Partition:
Use diskpart to select the disk, list partitions, select the recovery partition, and then delete it with delete partition override.
Extend the C Drive:
In Disk Management, right-click the C drive and select "Extend Volume". Follow the wizard to merge the now-unallocated space.
Recreate the Recovery Partition:
If you want the recovery partition back, you'll need to create a new partition, format it, and then re-enable WinRE using reagentc /enable.
Now, let's continue with our patching…
I reboot the VM and restart the process. Here are the following steps.
