2. To work around this issue, you can generate a new certificate. To do this, follow these steps:
- Shut down or save all virtual machines.
- Restart the Hyper-V VMMS.
- Start the virtual machines.
Because the Hyper-V VMMS certificate is valid for one year, the update has to be applied to prevent this issue from occurring in the future
