This System Update includes features for networking, security, and accessibility issues. It is part of the Windows 98 Customer Service Pack, which includes the following components:

• Windows 98 System Update
• Outlook® Express Year 2000 Update
• Windows 98 Year 2000 Update 2

This system update addresses the following issues:

• Active Accessibility
  This update addresses issues with color schemes when using Microsoft® Active Accessibility options.
• Computer Does Not Resume To Recognize USB Device From Standby
  If you connect a Universal Serial Bus (USB) device to your Windows 98-based computer while the computer is in Standby mode, the computer does not resume. The computer remains in Standby mode and may not recognize the USB device once it has resumed.
• Bulk Transfer URBs Can Specify More Than 64 Bytes
  The Universal Serial Bus (USB) 1.00 specification defines bulk transfers to be 4, 8,16, 32 or 64 bytes. However, the TransferBufferLength field of _URB_BULK_OR_INTERRUPT_TRANSFER can specify a much larger byte size. The USB specification limits the bulk transfer size to a maximum of 64 bytes at the port driver level.
• Computer with Plug and Play Network Adapter Is Not Found
  After you have upgraded to Windows 98 on a Windows 95-based computer with a Plug and Play Network Interface Card (NIC) installed, your computer may not be visible in Network Neighborhood to other computers on the network.
• System Policy to Require Validation by Network May Not Work
  If you are using a system policy that requires validation by the network for Windows access, you may be able to access the desktop even when the network does not validate your user account.
• Computer Hangs After 49.7 Days
  If your computer is left running for 49.7 days without restarting, your Windows 98-based computer may stop responding (hang). This is caused by a problem with the timing algorithm in the Vtdapi.vxd file.
• New Dialing Rules for Spain and Italy Require TAPI Update
  A new numbering and dialing plan for Spain became effective on April 3, 1998. The previous numbering and dialing plan was discontinued on June 5, 1998. As a result, when using a computer running Windows 98 you may not be able to correctly dial long-distance telephone numbers if your current dialing location is in Spain or Italy.
