To resize a partition:
The Technician Edition ISO (v8.7 in particular) is prized because it was the last version before AOMEI introduced stricter online activation checks. Many IT pros keep a copy of this exact build on a USB drive for offline emergency cloning and partition recovery on unlimited machines (that’s the “Technician” license—one copy, many PCs, no per-seat fees). It lacks the fancy new UI of v10+, but it’s rock-stable, small enough for a CD-R (approx. 130 MB), and doesn’t require an internet connection to work. aomeipartitionassistanttechnicianedition87iso
