Creating SSL PFX Certificate for IIS Windows

To create a PFX certificate file you can import into IIS on Windows from an openssl private key and certificate file on Linux, use the below command:

openssl pkcs12 -export -legacy -out iis_certificate.pfx -inkey your_private_key.key -in your_cert.crt -certfile your_chain.crt

Fix for Older SSH Keys Not Working on Windows Git

If your old SSH keys are not working on Windows after installing the latest Git client and tools, and you're being prompted to login (~/.ssh/config configuration being ignored), the fix is to add the following line to the bottom of the C:\Program Files\Git\etc\ssh\ssh_config file:

Host *
	PubkeyAcceptedKeyTypes +ssh-rsa

That's it.  It will work again.

Creating a SFX Installation Wizard with WinRar that Can Modify Registry Settings

WinRar's "SFX options…" dialog does not contain any information or guides that help you modify registry settings after the files for your installation have been extracted.  This is a hinderance, but it is extremely possible to modify registry settings by running a batch file after the installation has been completed.  First, make sure the .bat file is included with the rest of your installation files that you selected before making the SFX archive.  In the "Advanced SFX options" window, click on the Setup tab.  Under "Run after extraction", type in just the name of the .bat file you're going to be running.

The Batch File Itself:

This template batch file checks to see if the operating system is 32-bit or 64-bit.  This is an important distincting as it will affect how you setup keys for each type of operating system.  64-bit system keys are usually placed in the Wow6432Node key, so it is important to make this distinction so that your registry settings will work properly.  This batch file called "Program Registry Adder 1.0" provides examples on how to add and modify registry keys depending on the operating system type.

Adding Keys with a .bat (batch) File:

To add specific keys, you use the following parameters:

REG ADD "HKLM\SOFTWARE\My Proggy\" /f /v "InstallDir" /t REG_SZ /d "%PPROG%

The first parameter specifies which hive and key should be created.  The /f flag forces the addition.  The /v flag is the name of the key that should be created.  The /t flag specifies what type of Registry key should be created.  The example uses REG_SZ, which is just a string.  The possible types are:

The /d flag contains the value of the key.

Conclusion

Using both a self extracting installation wizard and a batch file for registry key settings makes for the perfect free to use professional looking installation script. You can always run the batch file silently by removing all pause statements in the script. 

Windows XP, Vista, and Windows 7 :: Keep Num Lock On at Startup

Despite what Microsoft claims, I've seen some computers not revert back to their last set num lock setting when Windows was last shut down.  Granted, this could be caused by Enterprise configurations.Here's a simple batch file that should keep Num Lock always ON when a user logs in.  It may or may not need to be run with administrator privileges based on your enterprise configuration.  I've had several users complain about the fact that Num Lock is turned off when they turn on their computers in the morning.  As a result, this batch file allows you to enable the setting that keeps num lock enabled after a user logs in with minimal effort.  I'm still under the impression that this is more work than the user simply pressing the num lock key to turn it back on.
