To be able to integrate updates (and SXS extracted packages) for Server 2008R2 on Windows 7/WinPE and vice-versa. To be able to integrate standard Windows 7's LIP (not MUI) on Server 2008R2/WinPE.
To clarify there are two branches of installers One (v12.x) by abbodi which is based on DISM and stock cabs + modified files the other V.8.8.x by T-S which doesn't use DISM at all, its basically a script that put in place the necessary files registry settings, services and so on. The former is conceptually more elegant but does not work on relatively recent windows, and also is prone to problems if uninstalled/reinstalled and generally on non virgin (if supported) windows installations. There are (or there were) few ways to fool windows DISM to accept a .cab not meant for a specific version, one of them was to export the package registry branch, editing it with the w8.1 version re-importing it, install the cabs, then remove the added registry settings. Nowadays is still possible to install an unintended cab, but that must be done offline, from a parallel OS (Or win PE), using the unpacked cab and editing the *.mum files, doing that may break monthly updates, given DISM has evolved in a way pickier thing than it was in 2015/2016. P.S. as stated above there is now a third kind of installer by garyan2, which is based on .msi just like a normal program (but it's available in x64 flavor only, which is a pity)
Can you post links about these two? It is intended for Windows 7/Server 2008R2 era, so probably should work.
Frankly I have not any link ready to any ready meal recipe, as those are methods found after long search and discussions Whatever Using the (online) registry method is relatively simple Launch regedit as trusted installer using nsudo/runasti or alike Export HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing\Packages Open the resulting file and replace the windows version with the one of the package you want to install (say 10.0.19041.1) Import the reg file, install your cab using dism. To remove the imported registry values edit the .reg again and add a - to the keys you want to remove (practically change any lines starting with [HKLM to [-HKLM. (EXCEPT THE FIRST LINE!!!! or you will remove the whole packages key) and import the .reg again
.mum files are also needed for online spoofing @maxtorix check install.cmd / dism.reg / dism folder from WMC_6.3.9600.16384_x64_v12.7z to see how it works
No, not with the technique I mentioned above. The cab/cabs are enough (at least that was the case with 2015/2016 and earlier). No idea if it still works on current CUs/SSUs
