No you can add PowerShell and modify the wim offline with DISM.  I saw the 
problem at another client that used a PowerShell script to prompt for computer 
name.  It gives you a recursion error in PowerShell but only on EFI machines.  
Since it was a simple script I just rewrote it in VBS so I'm not sure if there 
is a workaround, I didn't bother troubleshooting since its a known issue.

                 I'm using powershell scripts to manipulate the TPM chip and 
maintain other BIOS settings.  I am also using it to make calls to webservices. 
 It is not done in the full OS.  Same for MDAC, I use ZTIGather to pull data 
from the MDT Database, which I am all but certain uses MDAC.        
            I wonder if it is possible to use DISM to add components to the 
base WIM outside of SCCM.  i don't know what function is broken --- is it that 
you cant customize the boot WIM components from inside of SCCM or is it that 
you can't customize the components at all?  I am going to need ADSI to be 
installed and I also have to add components for 802.1x -- those I do manually 
outside of SCCM to the base boot WIM.  I know how to do that OK,  but I do need 
those components to work and be left alone when building boot images in the 
driver injection part and making USB sticks and deploying the Boot images to 
DPs.           
            Is it that Powershell and MDAC components can't be added to WinPE 
10 (RTM), that they can't function when they are added, or is it that SCCM 
can't add the components automatically in its internal Boot Image creation 
process?   That article i linked from Microsoft just alludes to problems in 
WinPE 10 RTM mentioning MDAC and Powershell, and says the problems are even 
worse in WinPE 10 from 1511.  so... that's what my problem is.  I don't have 
weeks to burn trying a lot of things on my test hardware that are already known 
to not work - so that is why I was planning to sit and wait, thinking I had 
until 2020 to figure it out.  Now there is a hard stop of July 2017 on Win 7 
for all the new computers we are receiving and that sounds much sooner than 
2020.  Meanwhile from research it sounds like there are significant problems in 
Windows 10 deployments still...  but people could be overblowing the problems, 
but Microsoft could also be downplaying them.

                                         I do use several PowerShell scripts in 
my task sequence, but they all kick off after the OS is applied so it's no 
longer running in WinPE. Where in the task sequence are your PowerShell scripts 
running?                       
                        The newer ADK supposedly fixes those problems, but i 
couldn't get it to work it kept giving me hardware errors.  I don't use MDAC so 
I can't comment on that issue.

                This post by Aaron says that win 10 ask (rtm) has problems with 
powershell and MDAC. Both of which I need to use.  Are those problems resolved 
in some way?

                                             I'm just wrapping a Windows 10 
project for a client and it went surprisingly well.  I installed SCCM 1511 with 
MDT 2013 u2.  The only issue I had was needing to roll back to The RTM Windows 
10 ADK due to a known WinPE bug.                              
                              I deployed a very large task sequence with over 
two dozen applications and also used the UDI wizard in MDT for other optional 
settings.  The client had lots of hardware including the surface pro 4 and 
surface book and things went very smoothly.  I used a MDT task sequence and 
customized it as needed.

                                                 I'm Looking for some advice 
among SCCM 2012r2 sp1, SCCM 1511, or wait a few more weeks...                   
                    
                                       Id like to get started with building a 
Windows 10 deployment and I am having trouble figuring out the best course of 
action.                                       
                                       I am currently deploying windows7 x64, 
Windows 7 x86, and Windows xp x86.  I am willing to drop support for XP 
deployment if I have to, but I still need to maintain SCCM client support for 
it.                                       
                                       I am using SCCM R2 with cu4 and MDT 2013 
integrated.                                        
                                       The last time I investigated everyone 
was complaining about lots of things being broken --- Powershell not working, 
DaRT being broken, ADK not installing components like MDAC in WinPE correctly, 
and driver packages exploding in size so I just decided to sit on the sidelines 
and let things settle down.                                         
                                       Then Microsoft announced that Skylake 
based systems will lose Windows 7 support in July 2017 so              that got 
my attention.  I need to get moving on Windows 10.                              
         
                                       So what is the current thinking?  
Upgrade SCCM to 1511 and MDT 2013 u2?  Upgrade SCCM to 2012r2 sp1 and MDT 
2013u1 and hold on to older Win10 ADK?  Hold out for a few more weeks for more 
bugs to get stomped?  Not sure what to do...                                    
   
                                       I rely heavily on the MDT database to 
drive ZTI task sequences.  DaRT, MBAM bit locker is important to me and I have 
several POSH based takes steps that need to work. I don't care about MDT 
standalone, but I do use the DB and the monitoring service- I just don't build 
any machines or images out of there.                                       
                                       I don't want to update to SCCM 1511 to 
find that that sticks me with a WinPE 10 version where other things I need are 
broken.  Also I'd like to maintain client support for XP so I'd rather not take 
a version of SCCM that can't manage XP unless I absolutely have to.             
                          
                                       Not sure where my next step should be, 
and I want to know what is going to break and what is not going to work before 
I go there.  It seems like there are a lot of people complaining about all 
kinds of things not working correctly with regards to Windows 10 releases 
especially around the ADK and I can't figure out what problems are fixed and 
what problems are real and what problems still exist.  Microsoft is not exactly 
forthcoming on what is not working so I have to rely on technet forums and the 
like and that is not always accurate advice...
