How to resize C drive by third party utility


New Member
I could manage to resize the system partition by using a third party utility software but think there must be more efficient way to do it. Here's how I did it:
1. I let the Surface 3 Pro boot from a USB bootable drive for the third party utility.
2. Noted that I could not resize the OS drive or any drive.
3. I disabled TPM and Secure Boot Control on UEFI.
4. Surface 3 Pro did not boot and instead got to recovery mode asking for recovery info.
5. I could not find the info anywhere and I reset the Surface 3 Pro.
6. I launched the third party utility again and could resize the partition this time.
BTW: I enabled TPM and Secure Boot Control and the drive can no longer be resized.
Any suggestion or comment is appreciated.
