Trying to expand Windows 11 volume

I have been running Windows 11 ARM via Parallels Dekstop 18 on my M1 Mac Studio for a while, and all is fine. I use it for gaming and that's it...

Recently I have been getting the dreaded "you are running out of space" message, and I went into Settings to clean up a bit, but alas, I need to expand my storage. I originally thought that 260GB would be enough, but I guess not.

With Windows shut down, I started by increasing the Hard Disk in Parallels to 400GB. and I thought I could just expand the disk in Windows 11 to use the extra 140GB... However, in Windows 11 Computer Management I only see a new partition, a recovery partition of 144GB, which I cannot get rid of, and there seems to be no way to expand my 255GB NTFS disk to include the 144GB.

Here is a screenshot of Computer Management in Windows 11:

How do I merge the two partitions, i.e. the 144GB and the 254GB ones?
 
Well, I finally figured it out...
  1. CMD
  2. DiskPart
  3. list disk
  4. selected disk #
  5. list partition
  6. select partition #
  7. delete partition
And if you get the message "Cannot Delete A Protected Partition Without the Force Protected Parameter Set", you'll need to use the override command in step 7:
7. delete partition override

After which the 144GB partition was gone, and I could expand the c: partition as usual...
