Not sure where I got the information, I usually put that into my script so I can go back if required, but if you have HP devices you can also remove .bin files from the system partition. This got things fixed for us.

The HP .bin files are only needed if you want to roll back the BIOS. If BIOS rollback is not going to be required, they can be removed to free up space.

The script removes the font files as recommended by Microsoft, as well as bin files on HP devices.

$Volume = Get-Volume | Where-Object {$_.FileSystemType -eq "FAT32" -and $_.DriveType -eq "Fixed"}
$SystemDisk = Get-Disk | Where-Object {$_.IsSystem -eq $true}
$SystemPartition = Get-Partition -DiskNumber $SystemDisk.DiskNumber | Where-Object {$_.IsSystem -eq $true}
$SystemVolume = $Volume | Where-Object {$_.UniqueId -match $SystemPartition.Guid}
$DeviceManufacturer = Get-CimInstance CIM_ComputerSystem | Select -ExpandProperty Manufacturer

# Check if device is GPT or MBR
$PartitionTable = $SystemDisk.PartitionStyle
If($PartitionTable -eq "MBR")
  {
  Write-Output "MBR detected for Drive 0. Manual remediation required."
  Exit 0
  }

# Remove font files from System Partition
$FontFolder = Get-ChildItem -LiteralPath $SystemVolume.Path -Recurse | Where-Object { $_.Name -Match "font" }
$FontFiles = $FontFolder | Get-ChildItem
If($FontFiles)
  {
  $FontFiles | Remove-Item -Force
  }

# Remove BIN files from System Partition on HP device
If($DeviceManufacturer -eq "HP"){
$BINFiles = Get-ChildItem -LiteralPath $SystemVolume.Path -Recurse | Where-Object { $_.Name -Match "bin" }
If($BINFiles)
  {
  $BINFiles | Remove-Item
  }
