Hash checking steps

Steps to check uploaded and downloaded ISO

Collect hash from each zip file (Before Upload)

Set-Location "C:\Users\ritracyi\Downloads\ISOs"

Get-ChildItem ".\" -Filter "*.zip*" | Get-FileHash | Export-Clixml .\UploadedZipFileHash.xml

Collect hash from each zip file (After Download)

Get-ChildItem ".\" -Filter "*.zip*" | Get-FileHash | Export-Clixml .\DownloadedZipFileHash.xml

Compare hashes against upload and download

Compare-Object (Import-Clixml .\UploadedZipFileHash.xml) (Import-Clixml .\DownloadedZipFileHash.xml -OutVariable 'downloads') -Property Hash -OutVariable 'NotEqual'

If nothing is displayed, the hashes are valid. Continue to build media. If a hash comparison comes back, there is a file that is not valid and must be re-downloaded and checked again. To find the invalid file run:

Retrieve invalid file name

Split-Path ($downloads | Where {$_.Hash -in $NotEqual.hash}).Path -Leaf

Steps to build OEM Media

Update MEDIA (intial/update)

Make updates to the OEM items if needed.
Run Update content on Media. This will build the initial or update content folder based on Deploymentshare used to build the media. WARNING: This may generate an ISO, but do not use this just yet

Add hash to customsettings.ini

NOTE Properties being added to the ini are:

Hash_DeployFiles=<hash>
Hash_DeployFolders=<hash>
Hash_DeployTS=<hash>
Hash_DeployWIM=<hash>

Store Hash Script

Command before Update Content

 .\LTIHashStoreUI.ps1 -WorkingPath "C:\DeployOEM\Content\Deploy" -StoreType StoreHash -TaskSequenceID WIN10_DEP

Check Hash Script

Command before OEM copy (OEM Tasksequence)

.\LTIHashCheckUI.ps1 -WorkingPath %DeployDrive%\Deploy -Title 'Validate Media' -CompareType StoredHash -TaskSequenceID WIN10_DEP -ShowStatusUI

Command after OEM copy (OEM Tasksequence)

.\LTIHashCheckUI.ps1 -WorkingPath %OSDisk%\Deploy -Title 'Validate Transfer' -CompareType StoredHash -TaskSequenceID WIN10_DEP -ShowStatusUI

Command before EUH UI (EUH Tasksequence)

.\LTIHashCheckUI.ps1 -WorkingPath %DeployDrive% -Title 'Validate Content' -CompareType StoredHash -TaskSequenceID %TaskSequenceID% -ShowStatusUI
