List of Windows and DOS Command Prompt Environment Variables

Windows and DOS (Command Prompt) have several environment variables which provides a set of dynamic values that points to important system locations or settings. Environment variables provided a way for running programs and batch command script to access the true discrete values, system paths or user management settings for configuration and processing purposes, avoiding the use of hard-coded values which may fail on some systems due to great variety of system configuration.

Tip: Batch file (.bat or .cmd) also uses environment variables to store temporary values for reference later in the script, and also to communicate data and preferences to child processes.
The table lists the common built-in environment variables in Windows operating system, together with their brief explanations and default values. All environment variables is not case-sensitive.

Windows XP: How to load and save sound schemes?

Windows XP store its sound scheme in the registry, under

HKEY_CURRENT_USER\APPEVENTS\SCHEMES\APPS

XP also stores her original .wav files for its sounds under C:\Windows\Media (assuming C is your root drive).

Thus, if you want to export this sound scheme for others, I recommend you follow these steps :

1. Put all your sounds in a single folder, e.g C:\OS_SOUNDS
2. Use Windows XP Control Panel > Sound and Audio Properties > Sound to configure Windows to use the sounds in C:\OS_SOUNDS
3. Export the registry key for HKEY_CURRENT_USER\APPEVENTS\SCHEMES\APPS

At this time, if you copy your C:\OS_SOUNDS to another computer (also under the same C:), and import the registry key you have just exported out, your sound scheme will be able to be transferred.

Transfer your PuTTY settings between computers

PuTTY is tops on the short list of applications I install first on any Windows machine. Over the years I've used PuTTY, I've installed it on a huge number of computers but I've always had one complaint; There isn't a configuration file I can backup or move to a new machine.

Getting all the little comfort settings correct for each SSH connection can be a pain. The third time you set emulation, keys, encryption type, etc. for each machine you regularly access, you lose patience. The fifth time you find yourself re-entering settings you might do what I did, find a better way.

Moving PuTTy settings between computers is an easy task once you know what's involved. We'll find the registry keys where PuTTy stores its configuration information and export them to a file. We'll then use that file we've made to import our configuration on the target machine.

Useful Shortcuts For Windows

RUN command shortcuts
I know there are a lot of people who love using the run prompt or the command prompt rather than using the mmc control, so here are some quick tips that you can use. Enjoy!

Symantec Backup Exec Migrate Data and catalogs to a fresh server or upgrade version of server

This week our backup server had to be replaced. We currently run Backup Exec 11d on Server 2003.  We are in the process of upgrading our servers to server 2008. At this point since there we are two versions behind would it be recommended to just wipe the server and start from scratch with 2008 and BE 2010 or upgrade BE 11d to 2010 and then upgrade to server 2008.

So there will be two options

In place upgrade:
1  : Upgrade BE11d to 12.5 and then to BE2010
2  : Upgrade W2003 to W2008

New Server upgrade: (With Same Name)
1  : On W2003 Server upgrade BE11d to 12.5 and to 2010
2  : On W2008 install BE2010 and migrate BE Databases from W2003 to W2008.

7-Zipping multiple folders to separate/individual zip/archive files

The problem was I had several folders I wanted to zip into individual 7z archives.  7-zip lacks a ‘Add to “*.7z”‘ explorer context for multiple selected files or folders (even though it does include a ‘Extract to “*\”‘).  Nor does this option appear within the application itself or via the command-line.  I seem to recall this feature being available in the Explorer contexts for some ZIP program I once used (I think it was TUGzip), but I wanted to choose quite aggressive compression settings for the archives and I didn’t think this would be achievable except via the command-line.

So using a bit of Google skills I discovered the ‘for… in… do’ batch command.  Which is quite powerful and I’m sure will come in handy again now that I know about it. Coupled with the 7-zip manual I arrived at a batch file with this line in it:

For 7z archive files

for /d %%X in (*) do "c:\Program Files\7-Zip\7z.exe" a "%%X.7z" "%%X\" -mx=9 -ms=on -md=26 -mfb=256
