Burn Image context menu item missing in Windows 7

English doesn't have a standard way of framing a question whose answer is an ordinal number. (Although, which and what can be used but they don't cover all the cases. Some familiar examples are: What grade are you in?, On which floor is your apartment?.

You can try framing the question in several ways but it doesn't guarantee that the answer will include an ordinal number. The context might shape the question also. Some possible questions for the OP are: "What child are you in your family?", "What number child are you in your family?", "Where do you come in your family?", "What is your birth order in your family?". However, you can always get answers like youngest, oldest, middle and such.

"What number" type of question in this context is not that usual and the answer can be a cardinal number also. For example, I am number two. When you start including phrases like where do you fall, birth order, age order etc.; the question gets unnecessarily long and formal, and it wouldn't sound natural in a conversation.

If you really want to get an ordinal number as an answer and sound natural also, I would suggest using the ordinal numbers in the question. For example:

What child are you (in your family)? First, second, third?

Most probably the answer will include the ordinal number, except the answer can be I am the only child.

Or, you might know the number of siblings (let's say three) and you can ask:

Are you the first, second or third child?

On the other hand, there are non-standard interrogative words that you can use in English but they don't sound natural. They are whatth (whath), whichth and how manieth. They include the usual interrogative words plus the suffix -th that forms ordinal numbers.

Whatth (whath) is the only one that is mentioned in a dictionary and it might be somewhat more acceptable than the others. Wiktionary includes a definition and example usages:

(nonstandard) Which ordinal number.

Thanksgiving is on the whatth of November this year?

In many languages, this kind of interrogative word is standard unlike English. Here is a list from omegawiki.org:

Here is an explanation about ordinatives from a credible source (Explorations in Functional Syntax: A New Framework for Lexicogrammatical Analysis by George David Morley):

Ordinatives: Exact ordinatives are known as 'ordinals', e.g.

    The first/second/fourth/fifty eighth shall be last.

They mark the precise numerical position of the entity under consideration in the order/sequence and are more fully known as ordinal numerals. However, they do not always require to take an article. As ordinatives, they answer the question 'Which?' in respect of numerical position, equivalent almost to asking 'the how-many-eth?' or 'the whichth?'.

Ordinatives may also be inexact, including words which mark the relative or non-numerical position of an entity in a series., e.g.

    The next/following/last is the best scene.

Some uses require an article, some don't. They answer the question 'Which?' in respect of relative sequential position but only in the sense of 'the whichth?'.

The above will work but an easier fix in Windows 7 is to go to control panel, select "default programs" then select "associate a file type or protocol with a program", this will display a list of file types, select the ".iso" file type then press the "Change Program" button, then select "Windows Disk Image Burner". If it's not in the list, browse to C:\Windows\System32\isoburn.exe. Press "OK". All done. Right clicking an iso file will now display "burn disk image".

Have you installed any other CD\DVD burning softwares? If so, it could be that they've associated themselves with ISO files. Try selecting the file, then right clicking it, then selecting "Open With" and see if Windows Disc Image Burner is one of the selections. If it is, just select it as the default program to open ISO files with with.

I tried the above fix, but .iso wasn't in the list of available file types. Right clicking on the iso file, selecting properties -> Open With allowed me to select Windows Disk Image Burner. Afterwards, the context menu contained the correct options and the .iso file type was available in the Default Programs list.

Good answers and comments; My comprehensive take on this question,and generalising, may I give a set of instructions building on previous answers to solve the problem?

In Windows 7, to force an Open With... to appear on the context menu (if it doesn't already!) when right-clicking a file, do the following:

1. Right-click on the file.
2. Choose Properties.
3. At the end of the line which starts Open with:, click on the Change... button.
4. Click on the 'v' chevron to open up Other Programs.
5. If the default program is not on the list shown, click on the Browse button.

6. You will now have to search for the utility program that you require to open the file. e.g. to process an ISO file, the utility required is: Windows Disc Image Burner and the program file to do this is isoburn.exe which is in the C:\Windows\system32 folder.

   Select this file and click OK. This will put an Open with... on the context menu, and also cause the ISO file to select the Windows Disc Image Burner application as the default.

Information on what executable file does what can usually be found by searching the web.

Yes, changing the file association by right-clicking the .iso and doing it in the Properties was the way I solved the problem. No other software was on my system as the default CD burning app nor was .iso in the file association list.
