Close Disk Management

Click your Start Button, then just type cmd

From the resulting list, right click Command Prompt and choose 'Run as Administrator'

Paste this command and hit Enter:

diskpart

select volume x

extend filesystem

When that completes, close Command Prompt and try shrinking that partition again in Disk Management
