+# Frequently Asked Questions
+
+
+## Which build do I choose?
+This is a question only **you** can answer.
+
+
+## Which build entry do I choose?
+Most builds will be available as one of the following:
+ * Cumulative Update (AKA „***Update** to [...]*”)
+ * Feature Update (AKA „***Upgrade** to [...]*” or no special name at all)
+
+If you want to create an updated image or you're not sure, choose the **Feature Update**.
+
+So: _Cumulative Updates generally aren't very useful, avoid them._
+
+## How do I choose Enterprise/Education or other editions?
+Select their **base edition** first.
+
+| Virtual Edition      	| Base Edition 	|
+|----------------------	|--------------	|
+| Enterprise           	| Pro          	|
+| Education            	| Pro          	|
+| Pro Education        	| Pro          	|
+| Pro for Workstations 	| Pro          	|
+| IoT Enterprise       	| Pro          	|
+| Home Single Language 	| Home         	|
+
+You can select the **virtual editions** after you choose to **add additional editions** (third **Download method**).
+
+
+## "There are no languages available for this build."?
+This means the chosen entry is **not** a complete build of Windows.
+
+It's probably one of the following:
+ * standalone update.
+ * Server build without metadata
+
+Those entries **cannot** be made into Windows images. Their files can sometimes be useful though.
+
+If you see this on a regular build of Windows or Windows Server, that means it's metadata ESD is unavailable.
+
+
+## Debloat?
+No. Don't.
+
+
+## There's a build with a `(2)` in its name. What does this mean?
+Most often that the build was pushed to more than one channel.
+
+Alternatively this could be a build of a different release type that was mistaken for a duplicate.
