If you are setting the Asset Tag the same name that the computer is, it makes sense to only have to input it once. I created a powershell script that will do the following:

If VM or Mac: Exit 0

If  computer exists in SCCM: Exit 0

If AssetTag Exists/Not empty: Set OSDComputerName to AssetTag, Exit 0

If AssetTag doesn't exist: Bring up an error message, Exit 1

Tested with HP and Dell machines.

Update: Added optional script that uses the HP Ownership Tag

How to use:
Create a package for the script

Copy serviceUI.exe (From MDT Toolkit) to the same folder.

In the Task Sequence after initial format of the drive create a Run Command Line step using the package that you created

with the command: ServiceUI.exe -process:TSProgressUI.exe %SYSTEMROOT%\System32\WindowsPowerShell\v1.0\powershell.exe -NoProfile -WindowStyle Hidden -ExecutionPolicy Bypass -File AssetTag.ps1

Thanks Nickolaj and Dave Green for the initial form

Quick Post on the install order of  - Use your favourite App Packaging Wrapper / PSADT

Update: CloseApp Line for PSADT: 

1. If package has Exceptions
   Exceptions\ExceptionDeployer.exe --workflow=install --mode=pre --installLanguage=en_US
   Don't do en_GB - seems to break acrobat
2. If package has Acrobat
   Build\Setup\APRO15.0\Adobe Acrobat\setup.exe
   Always do this where applicable or acrobat may break
   If you want to customize Acrobat customize the msi in here using the Acrobat DC Customization Wizard
3. Run main setup
   Build\setup.exe --silent
   If you don't use silent, it never exits
4. If package has exceptions
   Exceptions\ExceptionDeployer.exe --workflow=install --mode=post --installLanguage=en_US
5. Firewall Exceptions
   Node.exe: netsh advfirewall firewall add rule name="Adobe Node"  dir=in action=allow program="%Programfiles%\adobe\adobe dreamweaver cc 2017\node\node.exe" enable=yes
   Scout.exe: netsh advfirewall firewall add rule name="Adobe Scout"  dir=in action=allow program="%Programfiles%\adobe scout cc\scout.exe" enable=yes
6. Disable CC startup and set all office addins to only load if user chooses to
   regedit.exe /s AcrobatAddinReg.reg
   https://1drv.ms/t/s!Apq2Xflj18I1wGkFeyX_T3lbtM5G
7. Remove shortcuts bat
   REM Delete Shortcuts
   del "%ALLUSERSPROFILE%\Microsoft\Windows\Start Menu\Programs\Adobe Creative Cloud.lnk" /F /Q
   del "%PUBLIC%\Desktop\Adobe Creative Cloud.lnk" /F /Q

If you are putting the apps in a base image you may need to run the main setup.exe if you want to avoid Acrobat crashing on first use.

I don't think outlook should be making PDFs.. You can disable the add-ins with group policy

Download Office ADMX files
2013: https://www.microsoft.com/en-au/download/details.aspx?id=35554

2016: https://www.microsoft.com/en-au/download/details.aspx?id=49030

Copy the files under ADMX to your policy central store

Now create a group policy, browse to

User Configuration > Administrative Template > Microsoft Outlook 2016 > Miscellaneous > List Of Manage add-ins

Edit the policy setting, click show

Then specify the add-ins you want to disable with a value 0

To block other add-ins you need to find the progID for the addin, they can be found in the registry for each app in the suite:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Outlook\Addins or HKEY_CURRENT_USER\SOFTWARE\Microsoft\Office\Outlook\Addins

To block Adobe out of Office altogether:

Admin Templates - For each List of manage Add-ins

Microsoft Excel 2016:
PDFMaker.OfficeAddin 0

Microsoft Excel 2013:
PDFMaker.OfficeAddin 0

Microsoft Word 2016:
PDFMaker.OfficeAddin 0

Microsoft Word 2013:
PDFMaker.OfficeAddin 0

Microsoft Powerpoint 2016:
PDFMaker.OfficeAddin 0

Microsoft Powerpoint 2013:
PDFMaker.OfficeAddin 0

Microsoft Outlook 2016:
AdobeAcroOutlook.SendAsLink 0
PDFMOutlook.PDFMOutlook 0

Microsoft Outlook 2013:
AdobeAcroOutlook.SendAsLink 0
PDFMOutlook.PDFMOutlook 0

Another option (less harsh) is to change the load behaviour to 2 via registry after install or possibly a preference. This makes the plugin not loaded by default but allows the user to load it manually.

Example Reg https://1drv.ms/t/s!Apq2Xflj18I1wGkFeyX_T3lbtM5G

If this happens during OSD, it is likely due to 2 settings in the BIOS.

I recommend

WIN7 -

Boot mode: Legacy
Sata mode: AHCI

Win10-

Boot mode: UEFI
Sata mode: AHCI

Update: Adding more scratch space to the boot wim seems to have resolved the problem on Windows 10, Windows 7 seems to still have issues.

Update: This update is also in Windows 10 CU 3163018, causing the same error. No workaround yet 

If your build and capture is failing at the capture step make sure you don't have the cumulative Security Update for IE11 KB3160005. It's somehow stopping the registry load part of the step.

There is an issue that causes the login to be significantly slower when using Folder Redirection and NetApp.

The problem is a file lock occurs on the Desktop.ini files during login.

Our current workaround is to use a logoff script to delete the desktop.ini

Download DeleteDesktopIni.zip

It's very easy to customize the trusted sites for users by using group policy preferences without locking the settings down however what about websites that need to be ran as a different user?

To work around this I created a simple C Sharp program that sets the registry before launching the site in IE

Zones:
Value Setting
------------------------------
0 My Computer
1 Local Intranet Zone
2 Trusted sites Zone
3 Internet Zone
4 Restricted Sites Zone

Create the Installer:

Compile the package and copy it to where you want it on the clients system. Then create a shortcut to the exe.

Copy the exe and shortcut to your network share.
Create an Install.bat:

Deploy!

This problem will increase more and more as everyone starts to use wim's instead of the OS media in SCCM.

There are a few workarounds for this problem however the best method is to force the new OS the reevaluate Drive Letters with 3 easy steps after applying the OS

Create a Run Command Line step for each of the 3 commands

Reg.exe load HKLM\Temp %OSDTargetSystemDrive%\Windows\system32\config\system

Reg.exe delete HKLM\Temp\MountedDevices /va /f

Reg.exe unload HKLM\Temp

This forces the default behaviour of Windows to choose the drive letter.

If you are getting alot of error 2719 under SMS_INVENTORY_DATA_LOADER in a multiple user enviroment such as a lab of computers consider tweaking the data you are collecting.

Inventory Data Loader failed to process the file G:Program FilesMicrosoft Configuration Managerinboxesauthdataldr.boxProcessH5CCBXME.MIF because it is larger than the defined maximum allowable size of 5000000.

Solution: Increase the maximum allowable size, which is defined in the registry key HKLMSoftwareMicrosoftSMSComponentsSMS_INVENTORY_DATA_LOADERMax MIF Size (the default is 5 MB), and wait for Inventory Data Loader to retry the operation.

Solution is not increasing the maximum allowable size and make your DB massive.

In a multiple user environment the class that will be expanding those mifs is the 'CCM_RecentlyUsedApps'.

To cut the fat go to the Administration pane in SCCM 2012, then Client Settings. Right click 'Default Client Settings' and choose properties.

In the new window click 'Hardware Inventory'

Click 'Set Classes'

Search for 'CCM_RecentlyUsedApps', expand it. Is up to decide what you really need but we have deseleted the following.

Get the Servicing Exstension from Microsoft NOW as it does all the work!!! http://blogs.technet.com/b/configmgrteam/archive/2014/12/09/now-available-microsoft-system-center-2012-configuration-manager-servicing-extension.aspx

Once you have this, in the Admin node, there's a site servicing section -> client targeting. You click 'Create Query' and it makes a nice query for your collections.

Then you go about creating your collection.

click next. Select Add Rule -> Query Rule

Click Import Query Statement and choose the nice query microsoft made for you.

Deploy the cumulative update to the clients.
