   [IMAGE] IMAGEMAP This page lists the fixes contained in the
   Microsoft&reg; Windows&reg; 95 Service Pack 1 Update. 
    1. OLE32 Update
       The Windows 95 OLE 32 update addresses file-management behavior in
       Microsoft Word, Microsoft Excel, and Microsoft PowerPoint® for
       Windows 95. Because of the way these applications use OLE for file
       storage, files created by these applications might contain
       extraneous data from previously deleted files. This data is not
       visible while you use the applications. However, when such a
       document file is viewed by using Windows Notepad (for example), it
       might be possible to see pieces of information from the previously
       deleted files. This could pose information security or privacy
       concerns if you distribute electronic versions of files created
       using these applications.
       
       The OLE 32 update addresses this problem. Although the problem is
       known to occur only in Microsoft Excel, Word, and PowerPoint for
       Windows 95, the OLE 32 update is designed to prevent any
       application from potentially causing the same problem.
       
       Notes
          + If you use Microsoft Office with Windows NT™, this problem
            does not affect you, because the operating system initializes
            (clears) any disk space used by deleted files.
          + If you use Microsoft Word 6.0, Microsoft Excel 5.0, or
            Microsoft PowerPoint 4.0 with Windows version 3.1 or on an
            Apple® Macintosh® computer, contact Microsoft Customer
            Services to obtain the "C" maintenance releases of these
            products. Early releases of these versions are known to have
            a similar extraneous-data problem, which is fixed in the "C"
            releases. If you use Microsoft Word 6.0, Microsoft Excel 5.0,
            or Microsoft PowerPoint 4.0 with Windows 95, you should also
            obtain the "C" releases of these products.
   
       
    2. Microsoft Windows 95 Shell Update
       This update to Shell32.dll makes it possible to browse NetWare®
       Directory Service printers from the Add Printer wizard. The Add
       Printer Wizard is found in the Printers folder. This change is
       applicable to you if you have installed Service for NetWare
       Directory Services.
       
       This update to the Windows 95 Shell32.dll file also fixes a
       problem in which files copied onto themselves can be truncated to
       a zero-byte file size. This occurs only in the following
       circumstances:
          + When you copy a file onto itself using two different views of
            the same network resource (these can be different mapped
            drive letters or UNC connections to a network resource).
          + When you copy a file onto itself using a drive that was
            created by the SUBST command.
   
       
    3. Windows 95 Common Dialog Update for Windows 3.1 Legacy Printer
       Drivers
       In Windows 95, when 32-bit applications print using Windows 3.1
       monolithic drivers or the Windows 3.1 Pscript.drv / Unidrv.dll
       driver, the applications sometimes fail. This update addresses
       that problem.
       
    4. Vserver Update: File and Printer Sharing for Microsoft Networks
       This update is for a problem with File and Printer Sharing for
       Microsoft Networks and a certain UNIX® network client (Samba's
       SMBCLIENT). The update corrects a problem with share-level
       security documented in the Microsoft Knowledge Base on October 9,
       1995. The update also includes a correction for a similar problem
       with user-level security that Microsoft recently discovered as
       part of its internal testing of the new driver.
       
       Note
          + The phrase "Microsoft Networks" refers to Microsoft's
            networking software, not MSN™ (The Microsoft Network online
            service).
   
       
       Windows 95 enables users of the Samba SMBCLIENT to gain
       unauthorized access to the drive on which sharing is enabled by
       accepting certain specific networking commands. The Samba client
       is the only known SMB client that sends such networking commands.
       SMBCLIENT users do not automatically have access to the Windows 95
       drive, and must know the exact steps to send these commands.
       
       The updated driver prevents Windows 95 from accepting these
       commands, preventing SMBCLIENT users from accessing the drive on
       which sharing is enabled. With the updated driver, an SMBCLIENT
       user will have access only to those shared folders that a Windows
       95 user has designated.
       
    5. NWServer Update: File and Printer Sharing for NetWare Networks
       This update is for a problem with File and Printer Sharing for
       NetWare Networks which might affect data security for corporate
       users. If your computer is configured for file and printer sharing
       and Remote Administration is enabled, another user on the network
       might gain read-only access to your computer after the
       administrator has logged off the computer and before you have
       restarted your computer. To correct this problem, Microsoft has
       issued an updated driver for File and Printer Sharing for NetWare
       Networks. The updated driver ensures that only valid
       administrators have access to the computer's drive.
       
    6. Vredir Update
       The Vredir Update fixes a problem that affects only Windows 95
       users who use Samba UNIX servers. The problem arises from the
       basic Windows 95 and UNIX filename formats. UNIX allows filenames
       that include the backslash (\) and asterisk (*) characters, but in
       Windows 95, these are wildcard characters. Suppose that a Samba
       server contains a file named \\server\share\*.*, a legal UNIX
       filename. If a Windows 95 user connects to that server and tries
       to delete the *.* file by using Windows Explorer, all the files on
       \\server\share are deleted instead. This updated version of Vredir
       prevents this from happening by rejecting filenames that contain
       the \ or * characters.
       
    7. Windows 95 Password List Update
       The Windows 95 Password List Update protects your password file
       against potential security violations. When you connect to a
       password-protected resource, such as a network drive, you can
       choose to save that password. Windows then stores the password in
       an encrypted file on your hard disk. An algorithm was posted on
       the Internet for decrypting this file. If someone has access to
       your password file and knows the decryption algorithm, they may be
       able to decrypt it and the passwords it contains—and then gain
       access to the password-protected resources. The Password List
       Update provides vastly improved encryption that is 2^96 (2 to the
       96th power) harder to decrypt than the previous encryption method.
       
       
    8. Microsoft Plus! Update (System Agent Update)
       The Microsoft Plus! Update provides an updated version of Sage.dll
       to fix a minor problem with System Agent: When version 1.0 System
       Agent is running, programs that perform floating-point
       calculations might be slightly off in precision. This problem does
       not occur if System Agent is turned off.
       
       Note
          + If you do not have Microsoft Plus! installed on your
            computer, this update will have no effect on your system. If
            you install Microsoft Plus! at a later date (after the
            Microsoft Plus! Update has been installed), Microsoft Plus!
            Setup will leave the updated version of Sage.dll file on your
            system.
   
       
    9. Printer Port (Lpt.vxd) Update
       This Lpt.vxd Update adds support for ECP (Enhanced Communication
       Parallel) port bi-directional communications used with certain
       printers (such as the Hewlett-Packard&reg; LaserJet Series 4 and 5
       printers, some Lexmark LaserPrinters, and possibly others). It may
       prevent timeout errors when printing.
       
       Note
          + The Lpt.vxd Update was also included in the
            Drivers\Printer\LPT folder on the Windows 95 CD-ROM; however,
            it was not installed by default during setup.
