After a site upgrade with new version of ADK and WinPE to 1903 we run into a problem when booting a WinPE iso in VMware. The machine just stops/hangs/freezes with the Windows logo and with a high cpu usage. Turned out to be a known issue with VMware and WinPE/Windows 10 v1903 and a workaround to to disable vIOMMU on the virtual host. (This is a security feature that you have to decide if you want to disable). More information here: https://kb.vmware.com/s/article/68043
