Windows 10 - 1809 - installing RSAT Toolset - error code of 0x800f0950

Question

Monday, October 14, 2019 6:23 PM

I'm trying to install the RSAT tools on my new laptop. I'm running Win 10 Ent, ver 1809, build 17763.740.

When I try to install the tools from Powershell, I get this error:

Add-WindowsCapability : Add-WindowsCapability failed. Error code = 0x800f0950

When I try and install from the settings ->apps ->optional features, I get this error: "Install failed on xx/xx/xx  Check your Windows Insider Program settings."

We aren't even using/on/registered for the windows insider program.  I've already tried several suggestions about changing the registry & changing local group policy - none of those are working.

We don't have any corporate GP's or firewall rules blocking the install (that we know of).  It just stopped working - even for a PC that is connected to MS/internet from outside the corp. firewall.

We will be opening a case with MS, but thought I'd try here as well.

Thanks.

Problem is resolved. I needed to download and install MS updates.  Not sure exactly which one fixed the problem though.

Hi,

Please note that:

  1. Remote Server Administration Tools for Windows 10 can be installed ONLY on computers that are running the full release of Windows 10 Professional, Windows 10 Enterprise, or Windows 10 Education.
  2. Remove all older versions of Administration Tools Pack or Remote Server Administration Tools—including older prerelease versions, and releases of the tools for different languages or locales.

Open CMD with admin permission, then, type below command to check/repair system files:
SFC /SCANNOW

Then, type below command to make sure that RSAT is displayed within the result:
DISM.exe /Online /Get-Capabilities

If problem persists, please open Run, type “winver” to check detail OS build number, and provide me the screenshot.
