Windows 7 Rollups and preventing Updates

By david  //  Technical Tips  //  Comments Off on Windows 7 Rollups and preventing Updates

The following Windows Update Rollups have recently been made available in the Windows Update utility for Windows 7 SP1 and Windows Server 2008 R2 SP1.

If they are installed, there is a good chance that they will also install the Windows 10-related KBs that were previously hidden in the post Update – preventing Windows 10 upgrade.

After installing any of the Rollup KBs, I would recommend running the uninstallation scripts and following the instructions on that page.

Comodo and Ksoftware have been generously providing replacement certificates to current customers, as a result of the SHA-1 phaseout. The following link explains new code signing (Authenticode) steps, to support multiple Windows versions.

This impacts Software vendors/developers, and should not be confused with the SSL certificate replacement for browsers.

An important prerequisite mentioned in the article – the Windows 8.1 SDK version of Signtool is needed, for dual signing capabilities.

DLL Registration – Win32 vs .NET

By david  //  Technical Tips  //  Comments Off on DLL Registration – Win32 vs .NET

There are different methods for registering a Win32-based DLL, versus a .NET DLL. Win32 DLLs were typically created with legacy Visual Studio 6 C++, whereas .NET DLLs are created using Visual Studio 2005 or later.
To register a Win32 DLL, REGSVR32.exe is used. Format: REGSVR32 [dllname]

To register a .NET DLL, REGASM.exe is used. Format: REGASM [dllname]

The REGSVR32.exe tool is located in the library: C:WindowsSystem32
The REGASM.exe tool is located in the library: C:WindowsMicrosoft.NETFrameworkv2.0.50727 (or later versions of the .NET framework)

These Microsoft Links provide additional information regarding the registration tools:

Firefox Downgrade and Reinstallation

By david  //  Technical Tips  //  Comments Off on Firefox Downgrade and Reinstallation

About once a year, I go through the steps of completely uninstalling Firefox, deleting associated folders, and reinstalling the browser. This has an amazing impact on the performance of the product.
Even though the settings in Firefox are to not send any information to Mozilla, or retain data, a large number of files are being collected in the AppData folders.

In Firefox version 35, Mozilla added a feature called the “Hello Chat Video Service”, in the form of a button the toolbar. Around the same time, several of my favorite extensions began having compatibility problems with Firefox. To restore functionality from these extensions, I decided to downgrade to a lower version of Firefox.

Windows 10 Preview on Windows 7/VM Workstation

By david  //  Technical Tips  //  Comments Off on Windows 10 Preview on Windows 7/VM Workstation

To test the technical preview of Windows 10, I followed the instructions at Petri Windows 10 how-to to safely install the preview inside of a Virtual sandbox environment. One important note is to not add Virtual Tools to the VM environment until after Windows 10 has been installed. Otherwise, Windows 10 may encounter problems locating device drivers during the setup phase. Although Petri’s guide refers to Workstation 10, Workstation 11 can be used.

A 30-day trial version of VMWare Workstation can be downloaded here – VMWare Workstation Download Update: VMWare Player may be a better choice for most users, since it isn’t limited to a 30-day period. Download VMWare Player here

The ISO file download from Microsoft for Windows 10 can be downloaded here – Windows 10 Download
Windows 10 Screenprint

Oracle VirtualBox is also available as a VM environment for running Windows 10. My attempts to install the technical preview within VirtualBox, were not successful.
