Utilities

[This is preliminary documentation and subject to change.]

Utilities are products such as shell extensions, disk optimizers, antivirus software, certain query engines, and accessibility aids for people with disabilities.

Because utilities are considered Non-File-Based Applications, they are not required to provide OLE or UNC support.

They must meet all other general requirements contained in this document with the following special requirements, and with the following exceptions:

Special Requirements for Utilities

• Provide meaningful functionality on both Windows 95 and Windows NT. (Required)
• Extensively test any utility that uses the Exclusive Volume Locking function. (Required)

Special Exceptions for Utilities

• Certain components of utilities may be 16-bit, such as those that must use the Exclusive Volume Locking function, soft interrupts, or components that must communicate directly to 16-bit drivers. The user interface and other components of these applications must be 32-bit and use the Windows® 95 thunking mechanism to access these 16-bit components.
