If you often install freshly windows system, then my post maybe will be helpful for you. Mainly it’s more related to creation of system images for further deployments in corporate network, but sometimes it saves time even for home geeks. After installation you usually update from Microsoft Update thru internet or from WSUS – it takes a lot of time even on beefy computers. My idea is to do this work only once (later just to update in usual way from time to time). When you finished updates:

1. backup to second partition your system by builtin windows backup (bare-metal system backup)
2. sysprep and shutdown
3. from WDS server prepare capture disk (2-3 minutes work if you have windows deployment server) Using this instructions prepare USB boot disk
4. boot from above USB disk and capture to wim your updated windows system to updated.wim
5. now just replace on your windows USB distributive disk install.wim by updated.wim (using name install.wim). Now you have slipstreamed updates inside your distributive

for Windows10 and windows2016 you need also convert wim to esd (DVD, ISO has not install.wim, but install.esd):

dism /Export-Image /SourceImageFile:”win10prox64-updated.wim” /SourceIndex:1 /DestinationImageFile:”install.esd” /Compress:recovery

ps2

If you need to create updated distributive again – restore from backup system, update as usually again and repeat above steps again (just update process now will be considerably shorter). if you don’t have any more backups – then install system from updated.wim and make next incremental update – and so on.
