- 1.6 Vredir Update
- 1.7 Windows 95 Password List Update
- 1.8 Microsoft Plus! Update
- 1.9 Printer Port Update
OLE 32 Update
The Windows 95 OLE 32 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 another application, such as Windows Notepad, 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, Microsoft Word, and Microsoft PowerPoint for Windows 95, the OLE 32 update is designed to prevent any application from potentially causing the same problem.
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.
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
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.
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.
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.
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.
Microsoft Plus! Update
The Microsoft Plus! Update provides an updated version of SAGE.DLL to fix a minor problem with System Agent: When version System Agent 1.0 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.
If Microsoft Plus! for Windows 95 is not installed, this update will have no effect. If Microsoft Plus! for Windows 95 is installed at a later date (after the Microsoft Plus! Update has been installed), the updated version of SAGE.DLL will remain on the system.
Printer Port Update
This 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. Windows 95 Service Pack 1 will automatically install a version of the parallel port driver (LPT.VXD) that was also available previously on the Windows 95 CD-ROM in the \Drivers\Printer\LPT folder. This driver corrects problems seen on some ECP (Extended Capabilities Port) equipped machines.
