Is this for ESXi or Workstation?
From memory you can only shrink from workstation using VMware tools.
If its on ESXi your best bet is to resize using VMware converter (painful I know).
This blog post looks pretty good
"VMWare tools can also not be found under the control panel"
Is it in Add/Remove programs?
If you are using Workstation, ill need to spin up a windows 10 box and have a look to see if the option is still there.
Its not something I've tried in a long time.
It is for a workstation and VMWare tools does show up in add/remove programs. Please do let me know if you have some other insights/need extra information.
