You must first remove the plastic cover. By doing so you agree to accept and honor Microsoft rights to all TV dinners. You may not give anyone else a bite of your dinner (which would constitute an infringement of Microsoft’s rights).

This is a simple procedure. Remove the dinner from the oven and enter

Many users have reported that the dinner tray is far too big, larger than the dinner itself, having many useless compartments, most of which are empty. These are for future menu items. If the tray is too large to fit in your oven you will need to upgrade your equipment. Dinners are only available from registered outlets, and only the chicken variety is currently produced.

If you want another variety, call Microsoft Help and they will explain that you really don’t want another variety. Microsoft Chicken is all you really need. Microsoft has disclosed plans to discontinue all smaller versions of their chicken dinners. Future releases will only be in the larger family size.

Excess chicken may be stored for future use, but must be saved only in Microsoft approved packaging. Microsoft promises a dessert with every dinner after ‘98.

However, that version has yet to be released. Users have permission to get thrilled in advance. Microsoft dinners may be incompatible with other dinners in the freezer, causing your freezer to self-defrost.
This is a feature, not a bug. Your freezer probably should have been defrosted anyway.
