my friend told me : {I cant uninstall any features that you install it to win server,For example he installed web server to win server but he could not remove it anymore}.
is it possible to unable uninstall features after i install it?
how can i do that?
he installed the standard edition of windows server 2008 r2
Yes, you can remove features. You'll need to go to Server Manager, Expand the "Features" tab and then use the Add/Remove Features buttons on the right-hand side. IIS, though, your web server is a role rather than a feature.
For how to install server roles, have a look at this technet article.
Yes, it is possible - corrupt windows installs are always possible.
It also is possible he has no rights to remove it on the account he uses.
But otherwise - no, features can be added and removed.
