Uninstalled all default apps and can't reinstall them.

I uninstalled all the default apps (with CCleaner) knowing that each new build re-installs them. Build 14926 no longer re-installs uninstalled apps. I've tried every means I can find to re-install the apps but nothing works. Can I roll back to previous build (Build 14915), then upgrade to 14926 and have it reinstall the apps? If not can I install build 14393 from iso then upgrade to 14926 without loosing all my previously installed software i.e. Auto Cad, Revit, etc.?

Hi dchapin and welcome to Tenforums.
Starting with Insider 14926, Windows is no longer reinstalling what you deleted. I think you need to re-register the Windows Store, then install the apps that you want back.

Code:

Add-AppxPackage -DisableDevelopmentMode -Register "C:\Program Files\WindowsApps\Microsoft.WindowsStore_11606.1001.39.0_x64__8wekyb3d8bbwe\AppxManifest.xml"

I tried that code, it ran, but the apps didn't come back. However I did lose two or three I hadn't uninstalled. I tried reloading from Windows store but when I click "install" nothing happens. I also uninstalled the app installer.

Please read this thread; specifically posts #11, #35.

What will happen if I use a previous build iso. Will I loose all my installed programs?

No, you can not perform a repair install using an older version of Windows than what is on the system. You'd have to do a clean install if you're going to use an older ISO.
