Batch Scripting on Windows 7 - Windows 7 Command LineThere are numerous reasons that batch scripting can help users get a more full experience out of Microsoft Windows 7. They can be used to automate tasks just as easily as they can contain long commands that are not easy to work around. By starting with more simple models, a programmer can usually get the feel for what batch scripts are supposed to look like. That being said, anyone who has some experience with the command line can essentially take a group of commands that they've entered and use them as a makeshift batch script with no further editing.

PowerShell: Windows Command Line on Speed - PowerShellWho needs another shell? Unlike the Unix world, Windows hasbeen pretty consistent with the shell environment. First there was MS-DOS (COMMAND.COM) and later Windows NT (CMD.EXE). You can actually still get to COMMAND.COM if you really, really want to. But for all intents and purposes, these have been the only two shells Windows users have ever known.

Microsoft wants to change that. When .Net was announced in 2000, Microsoft promised everything would one day be .Net. Unfortunately, Microsoft stuck the .Net name on things that were not .Net at all, such as Passport.Net which had no managed code in it at all.

Computer Training Excuses - No ExcuseYou wouldn't go to a doctor who had never been to medical school, or hire a lawyer who never studied law. One side-effect of a world advancing as rapidly as ours is that fields are becoming more and more specialized and narrow. People can no longer get by on general knowledge in their careers, something I found out for myself not too long ago. I'd been out of high school for two years, scraping by on my own and picking up scraps of programming as I went. I saw all of the self-taught programmers breaking into the IT industry, and I hoped to do the same. After all, IT is one of the few industries out there where being creative and a quick learner is more important than a degree.

MD5 File Hasher 1.3 - MD5 File HasherThe hash function is a way of mapping a collection of information that can be various lengths in other values of fixed length. The values that the hash function gives are called hash values, codes, sums, checksums or simply hashes. MD5 is a cryptographic hash algorithm, which means that it takes information of arbitrary length and creates fixed lengths for it, a cryptographic hash value, in a way that any change of data (accidental or on purpose) leads to the change of that value.

What are Operating systems? - Operating systems The way that computers work is that they use something called an Operating System, basically a platform in the form of a low level software which enables programers and other people to make other, more complex programs.

Server - both a Web server and an office server. Windows 2000 Server lets users build Web applications and connect to the Internet.

Advanced Server - an operating for line-of-business applications and e-commerce. It contains all the functionality of the standard version of Windows 2000 Server, plus additional features for applications that require higher levels of scalability and availability.

Data Center Server - developed to work in high-traffic computer networks, it is designed for enterprises that need reliable high-end drivers and software. It supports up to 32-way SMP and up to 64 GB of physical memory.

What We Cover

This category mainly covers Windows 2000 Professional (W2Kpro) from a users' point and not server, advanced server, or data center which is mainly for use of Systems Administrators. However, to get heavy duty info for those operating systems you may visit our MCSE Certifications category which maybe just what your looking if W2Kpro is not your query.

Tips

Speed up the Boot Menu

Tired of waiting thirty seconds to boot Windows 2000 if you don't select from the boot menu? Speed up the booting process by only showing the available operating systems for just a couple of seconds.

Right-click "My Computer" on the desktop and choose "Properties". On the "System Properties" multi-tabbed dialog box that follows, click "Advanced". Click the "Startup and Recovery..." button. Then, on the "Startup and Recovery" dialog box that follows, next to "Display list of operating systems for ... seconds", select the number of seconds that you want the computer to wait before continuing with the default OS. When you're done, press "OK" to close the dialog box.

Desktop Disappearing?

Although Windows 2000 is more stable than previous versions of NT, in some situations, strange things can happen. If, for example, Explorer crashes, most of your desktop, including the "Start" button, disappears. To bring back Explorer without rebooting your machine, press CONTROL-ALT-DELETE. When the "Windows Security" dialog box appears, click the "Task Manager" button. If the "Windows Task Manager' dialog box appears as it should, select the "File" menu and then "New Task (Run)". When the "Create New Task" dialog box appears, just type in "Explorer" and press the "OK" button. Windows Explorer should then reappear, complete with the "Start" button.

Change Process Priority

Is a particular program or process running too fast or too slow? Is a program or process taking too much of your CPU time or can you allow a process or program to take more of your computing power? To change these settings for a particular process, just right-click on an empty area of your taskbar and choose "Task Manager..." On the "Windows Task Manager" dialog box that follows, select a process and right-click it. On the popup menu that appears, select "Set Priority" and choose one of the following priorities: "Realtime", "High", "Above Normal", "Normal", "Below Normal", or "Low". The lower the priority is on the popup menu, the lower percentage of CPU time will be delegated to said priority.

Note that depending on the process and your administrative rights to your machine, you may not be able to change a particular process's priority.

Put the Desktop in your Taskbar

Do you frequently multitask? If so, all of the windows created by running applications can quickly cover your desktop. If you'd like, you can make the desktop icons immediately accessible from your taskbar. Just right-click an empty area of your taskbar, choose "Toolbars", and check "Desktop". Your desktop icons will then be immediately accessible without having to minimize your current windows. If you have a lot of desktop icons, click on the two greater-than arrows (">>") to the right of your desktop icons and a popup menu will appear allowing you to select from any of the available desktop icons not immediately visible on your taskbar.

Changing DOS Window Titles

If you use DOS a lot, you may frequently have more than one DOS window open at once. Perhaps you'll have one a window for FTP, one for debugging a batch file, one for doing basic tasks such as displaying directories, etc. If so, it can get very confusing navigating between the different DOS windows since each of their titles just say "Command Prompt". If you'd like, you can change the titles of a DOS window so you can easily see what tasks you are performing in each window.

To change the title of a Windows 2000 command prompt window, just enter in the TITLE command, followed by your desired window title. For example, to name a DOS window "Debugging Window", just enter the following command at a DOS prompt:

TITLE Debugging Window

Save the Current Directory Name

Windows 2000 lets you temporarily store the name of the current directory that you are in, letting you recall the directory name later after you are doing other processing. This may be useful if you are jumping around DOS directories a lot, either manually or through a batch file.

To store the name of the current directory, or rather, to PUSH the name of the current directory onto the stack, enter the PUSHD command followed by the name of a directory that you would like to access next. For example, if you are in the "C:\Program Files" directory and want to push that directory name onto the stack, jumping to the C:\WINNT" directory, enter:

PUSHD C: WINNT

After you are done working in the "C:\WINNT" directory and ready to go back to the "C:\Program Files" directory, don't type in "CD C:\Program Files", just POP the old directory from the stack by entering:

POPD


Did You Know?

  • Windows 2000 is becoming the OS of choice for many web hosts due to its higher compatibility with ASP.NET applications.

  • An Indian discovered that in MS Operating Systems, nobody can create a folder anywhere named as "con". Not only con but you cannot create folders named as "aux" nor "nul". This is something pretty cool...and unbelievable... At Microsoft, the whole Team, including Bill Gates, couldn't answer why this happened! Try it out yourself...
