Hello,

The issue with Guest OS WA-GUEST-OS-7.56_202509-01

On 10/15 correspondent cmdlet returned:

Version Family IsActive IsDefault Label

WA-GUEST-OS-7.53_202506-01 7 False False Windows Azure Guest OS 7.53 (Release 202506-01)

WA-GUEST-OS-7.54_202507-01 7 True True Windows Azure Guest OS 7.54 (Release 202507-01)

WA-GUEST-OS-7.56_202509-01 7 True True Windows Azure Guest OS 7.56 (Release 202509-01)

Since 10/16 it returns False

Version Family IsActive IsDefault Label

WA-GUEST-OS-7.53_202506-01 7 False False Windows Azure Guest OS 7.53 (Release 202506-01)

WA-GUEST-OS-7.56_202509-01 7 False False Windows Azure Guest OS 7.56 (Release 202509-01)

WA-GUEST-OS-7.57_202510-01 7 False False Windows Azure Guest OS 7.57 (Release 202510-01)

There was similar issue in the past when released OS was made inactive by personnel mistake. Is it the same issue? Our Cloud Services already using September Guest OS.

Will 7.56 come back?

Sergei.
