You can easily trigger SCSI UNMAP in Windows via PowerShell:
Optimize-Volume -DriveLetter C -ReTrim -Verbose
On a Windows Server with GUI, you can use the traditional method of setting the display resolution but as there's no Control Panel nor Settings app on Windows Server Core, the only way is through Powershell with the Set-DisplayResolution cmdlet.
Set-DisplayResolution -Width 1024 -Height 768
The cmdlet above sets the resolution to 1024x768. It will prompt you to accept the change, if you don't want that, append -Force parameter.
To get the current display resolution, you can use the Get-DisplayResolution cmdlet.
The equivalent of creating a disk image from a folder like in macOS can be achieved in linux as well. You'll need the genisoimage package, which will install the mkisofs command. After that, you can easily create ISO files from a folder's contents. The additional flags, such as -J make the ISO Windows-compatibel.
mkisofs -J -l -R -V "Label CD" -iso-level 4 -o output.iso input_directory
On Windows Server Core installations, you don't have Disk Management available. But you can quickly initialize and partition a new disk via diskpart. Here's a quick reference to the necessary commands in order.
When trying to sync updates in vCenter LifeCycle Manager, it may fail and throw the following error:
Error: ‘integrity.fault.HostPatchInvalidVendorCode’
It is usually followed by a variety of error messages, such as: invalid vendor code XXX in patch metadata.
If there are no customizations in your vCenter, you can easily fix this by resetting the vLCM update database, as per KB2147284. Run the following commands from a shell in vCenter:
service-control --stop vmware-updatemgr /usr/lib/vmware-updatemgr/bin/updatemgr-utility.py reset-db rm -rf /storage/updatemgr/patch-store/* service-control --start vmware-updatemgr
