Update to Windows 95

Microsoft Windows 95 Service Pack 1 includes an update for Windows 95. Installing this updates your version of Windows 95 to version 4.00.950a. This section explains how to install the update and describes the contents of the update.

Note The update is designed to solve specific issues. If these issues do not apply to your configuration(s), you might not need to install the update. For more information about the Update, see the section "What does the Windows 95 Service Pack 1 Update do?" later in this document.

Updating a Single Computer

This section explains how to install the Service Pack 1 Update on a single computer running Windows 95.

To install the update on a single computer

1. Quit any applications that are currently running. If you use the Microsoft Plus! System Agent, right-click the System Agent icon on the toolbar, and then click Suspend System Agent.

   2. Insert the Windows 95 Service Pack 1 CD.

2. Double-click the Setup.exe file, and then follow the instructions on your screen.

When the Setup.exe program completes, your version of Windows 95 will be updated to version 4.00.950a.

To remove the update from your computer

1. Click the Start button, point to Settings, and then click Control Panel.

2. Double-click Add/Remove Programs.

3. Click the Install/Uninstall tab, click Windows 95 Service Pack 1, then click Add/Remove.

4. Follow the instructions on your screen.

During the update the Service Pack version of Net.exe is also copied to Netpwl.exe. This file can be used if Net.exe is overwritten. Net.exe may be overwritten by network setup while adding or removing network components.

The Service Pack includes an update to Microsoft Exchange that enables users to use shared (public) folders on the post office with Microsoft Mail. If you use Microsoft Mail, then after installing the Service Pack updates, you need to carry out the following procedure in order to use shared folders. (You do not need to carry out this procedure if you do not use the Microsoft Mail service in Microsoft Exchange.)

To reconfigure Microsoft Exchange to use shared folders (if you use Microsoft Mail)

1. In the \Admin\Componts\Updates\Exchupd folder, run Exchupd.exe.

2. In Control Panel, double-click the Mail And Fax icon.

3. Click the Microsoft Mail information service, and then click Remove.

4. Click Add, and then select Microsoft Mail from the list of services.

5. In the Microsoft Mail configuration dialog box , click the Connection tab.

6. In the Edit box, type the path to your Microsoft Mail post office.

7. On the Logon tab, type your mailbox and password.

8. To add the service, click OK, and then click OK again to save the changes to your profile.

This section explains what each Service Pack update does. Most updates address a specific problem or a specific configuration. These updates have previously been available to download from various electronic locations such as the Microsoft Web site and MSN - The Microsoft Network.

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.

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.

Microsoft Windows 95 Shell Update

This update to the Windows 95 Shell32.dll file 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)

  the SUBST command

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.

Vserver Update: File and Printer Sharing for Microsoft Networks

Microsoft is issuing an update for a known problem with File and Printer Sharing for Microsoft Networks and a certain UNIX shareware network client (Samba's SMBCLIENT). The update corrects a problem with share-level security documented in the Microsoft Knowledge Base on October 9th, 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 access 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 only have access to those shared folders that a Windows 95 user has designated.

NWServer Update: File and Printer Sharing for NetWare Networks

Microsoft was recently made aware of an issue 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.

Vredir Update

The Vredir Update fixes a problem that affects only Windows 95 users who use Samba servers. The problem arises from the basic Windows 95 and UNIX filename formats. UNIX allows filenames that include the \ and * 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.

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. Recently, 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 might 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.

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.

Microsoft Exchange Update

This update provides a version of Microsoft Exchange that supersedes the version of Exchange included with Windows 95. The updated version enables users running Microsoft Exchange with Windows 95 to access their Microsoft Mail shared folders. (The Microsoft Mail information service included with Windows 95 does not provide access to shared folders.)

Important To use shared folders with Microsoft Mail, you must reconfigure Microsoft Exchange after installing the Service Pack updates. To reconfigure Microsoft Exchange, follow the second procedure in "Updating a Single Computer" earlier in this document.

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 LaserJet Series 4 and 5 printers, some Lexmark LaserPrinters, and possibly others). It may prevent timeout errors when printing.

Notes The Lpt.vxd Update was included in the Drivers\Printer\LPT folder on the Windows 95 CD-ROM; however, it was not installed by default during setup.

The file dates on the updates have been adjusted to "12-31-95 9:50AM." Setup uses internal version information when updating files, so the date change will not affect adding the same components again from an electronic site or if you have previously installed them.
