Windows 2008 R2 Standard Server.
Server manager's Role and Features show error.
Yet, the patches were installed successfully. I have tried to reinstall the patch, the system said "it's already installed"
I tried to install "MS update readiness tool" patch, it failed to install.
Any idea, suggestion?
Thanks
