Vmware Vcenter Converter Standalone Unable To Start The Change Tracking Driver May 2026

It was 11:47 PM on a Friday. Sarah, a senior infrastructure engineer, was two hours into what should have been a routine P2V migration. The source machine: an aging Windows Server 2008 R2 box running a critical line-of-business app. The destination: a shiny new vSphere 7 cluster.

The next conversion attempt was clean. The driver started. The clone synced block by block. It was 11:47 PM on a Friday

She checked if the driver was even present. On the source machine, she opened C:\Windows\System32\drivers and looked for vmware-ctk.sys . Nothing. That meant Converter never installed it properly—or the OS blocked it. The destination: a shiny new vSphere 7 cluster

Sarah ran bcdedit /set hypervisorlaunchtype off , disabled Hyper-V from Windows Features, removed Device Guard via registry, and rebooted twice (the second to finalize). The clone synced block by block

A quick sc query vstor2-mntapi10-shared showed the driver service wasn't there either.

At 2:13 AM, the conversion finished. She shut down the source, powered on the VM, and the app came up without a hitch.
