Allowed WinPE instances

To allow a WinPE instance to run, the value corresponding to the command line parameter ‘ -instancename ‘ should be added to the below list. Read details about ‘SCCM – WinPE boot image setup’ in the previous section => Click here.

  • The feature can be used to rein in old USB and Full media boot devices.
  • This option helps administrators keep their USB boot devices up-to-date with the latest image.
  • Administrators should assign a new instance name, when changes are made to the WinPE boot image.
  • Use alphabets, numbers, – (hyphen) and . (dot); No other special characters are allowed. Cannot end or begin with a special character.
    Instance names can be up to 25 characters in length.

DCOM hardening issue.

This application fails to authenticate with WMI on the SCCM server because Microsoft has not yet hardened DCOM on their Windows Preinstallation Environment. We are working on a different approach, but it will only be released during the first quarter of 2024. But until that time, the only workaround will be to uninstall the update corresponding to KB5004442.
