How To Disable Windows Firewall ?

Allowing Connections Through the Firewall

In some situations, you want to allow other computers to initiate a connection to your computer . For example, you might use Remote Desktop, play multiplayer games, or chat via an instant messaging program; these types of programs typically require inbound connections so that others can contact you .

The simplest way to enable a connection is to click Allow A Program Or Feature Through Windows Firewall, a link in the left pane of the main Windows Firewall window . The list of programs and features that initially appears in Allowed Programs, shown in Figure 15-6, depends on which programs and services are installed on your computer; you can add others, as described in the following sections . In addition, program rules are created (but not enabled) when a program tries to set up an incoming connection . To allow connections for a program or service that’s already been defined, simply select its check box for each network location type on which you want to allow the program . (You’ll need to click Change Settings before you can make changes .)

How To Enable Windows Firewall ?




The Block All Incoming Connections check box in Customize Settings provides additional safety . When it’s selected, Windows Firewall rejects all unsolicited incoming traffic—even traffic from allowed programs or that would ordinarily be permitted by a rule . Invoke this mode when extra security against outside attack is needed . For example, you might block all connections when you’re using a public wireless hotspot or when you know that your computer is actively under attack by others.

How to edit Windows Registry?



Because of the registry’s size, looking for a particular key, value, or data item can be daunting . In Registry Editor, the Find command (on the Edit menu; also available by pressing Ctrl+F) works in the forward direction only and does not wrap around when it gets to the end of the registry . If you’re not sure where the item you need is located, select the highest level in the left pane before issuing the command . If you have an approximate idea where the item you want is located, you can save time by starting at a node closer to (but still above) the target .

After you have located an item of interest, you can put it on the Favorites list to simplify a return visit . Open the Favorites menu, click Add To Favorites, and supply a friendly name (or accept the default) . If you’re about to close Registry Editor and know you’ll be returning to the same key the next time you open the editor, you can skip the Favorites step, because Registry Editor always remembers your last position and returns to that position in the next session .

Registry Editor includes a number of time-saving keyboard shortcuts for navigating the registry . To move to the next subkey that starts with a particular letter, simply type that letter when the focus is in the left pane; in the right pane, use the same trick to jump to the next value that begins with that letter . To open a key (revealing its subkeys), press Right Arrow . To move up one level in the subkey hierarchy, press Left Arrow; a second press collapses the subkeys of the current key . To move to the top of the hierarchy, press Home. To quickly move between the left and right panes, use the Tab key . In the right pane, F2 to rename a value, and press Enter to open that value and edit its data . Once you the hang of using these keyboard shortcuts, you’ll find it’s usually easier to zip through the subkey hierarchy with a combination of arrow keys and letter keys than it is to open outline controls with the mouse .

Adding or Deleting Values

To add a value, select the parent key; open the Edit menu, and point to New . On the submenu that appears, click the type of value you want to add . A value of the type you select appears in the right pane with a generic name . Type over the generic name, press Enter twice, enter your data, and press Enter once more . To delete a value, select it and press Delete .

Changing Data

You can change the data associated with a value by selecting a value in the right pane and pressing Enter or by double-clicking the value . Registry Editor pops up an edit window appropriate for the value’s data type .

Adding or Deleting Keys

To add a key, select the new key’s parent in the left pane, open the Edit menu, point to New, and click Key . The new key arrives as a generically named outline entry, exactly the way a new folder does in Windows Explorer . Type a new name . To delete a key, select it and then press Delete .

Registry Data Types

The registry uses the following data types:

REG_SZ The SZ indicates a zero-terminated string This is a variable-length string that can contain Unicode as well as ANSI characters When you enter or edit a REG_SZ value, Registry Editor terminates the value with a 00 byte for you

REG_BINARY The REG_BINARY type contains binary data—0s and 1s

REG_DWORD This data type is a “double word”—that is, a 32-bit numeric value Although it can hold any integer from 0 to 232, the registry often uses it for simple Boolean values (0 or 1) because the registry lacks a Boolean data type

REG_QWORD This data type is a “quadruple word”—a 64-bit numeric value

REG_MULTI_SZ This data type contains a group of zero-terminated strings assigned
to a single value

REG_EXPAND_SZ This data type is a zero-terminated string containing an unexpanded reference to an environment variable, such as %SystemRoot% (For information about environment variables, see “Using Environment Variables” on page
968 ) If you need to create a key containing a variable name, use this data type, not REG_SZ

Internally, the registry also uses REG_LINK, REG_FULL_RESOURCE_DESCRIPTOR, REG_RESOURCE_LIST, REG_RESOURCE_REQUIREMENTS_LIST, and REG_NONE data types. Although you might occasionally see references in technical documentation to these data types, they’re not visible or accessible in Registry Editor

About Registry in Windows

Windows 7 is designed in such a way that direct registry edits by end users are generally unnecessary When you change some detail about your system’s confguration using Control Panel, Control Panel writes the necessary updates to the registry for you, and you needn’t be concerned with how it happens When you install a new piece of hardware or a new program, a myriad of registry modifcations take place; again, you don’t need to know the details On the other hand, because the designers of Windows couldn’t provide a user interface for every conceivable customization you might want to make, sometimes working directly with the registry is the only way to get a job done And sometimes, even when it’s not the only way, it might be the fastest way Windows includes a registry editor that you should know how to use—safely.

How to access the Windows Registry?

To get access the Windows Registry Editor:

1. Click the Start button, type regedit, and press Enter or click "Ok".




2. When prompted, click "Yes". And now you can use Windows Registry Editor.

Readyboost How To?

To enable ReadyBoost: 

1. Put your USB thumb drive into a USB port on your computer.
2. When the AutoPlay menu appears, click Speed up my System with Windows ReadyBoost.


Requirements for ReadyBoost

For a USB thumb drive to be compatible, it needs to have a minimum of 256 MB free space. Most modern USB thumb drives will meet the space and speed requirements of
ReadyBoost.

How Does ReadyBoost Work?

Solid state memory (what your USB drive uses) has excellent transfer speeds; therefore, it can be used to store and access data that is needed quickly. Windows 7 ReadyBoost uses the USB thumb drive as an extra cache between the processor and the hard disk. Unlike RAM, the data is stored on your thumb drive and can be used next time you use your computer—a great time saver if you use many different programs and run many of them simultaneously.

What is ReadyBoost?

ReadyBoost uses a USB thumb drive to create an extra cache of the most commonly used data, which is quickly accessible when needed. Microsoft’s website states:

Windows ReadyBoost [is] a new concept in adding memory to a system. You can use non-volatile flash memory, such as that on a universal serial bus (USB) flash drive, to improve performance without having to add additional memory under the hood.

Use ReadyBoost to Speed Up

Using Windows ReadyBoost is a great way to improve the performance of your computer when doing your day-to-day tasks.

Memory Diagnostic Tool

Memory (RAM) can become corrupted and not work properly. Usually, a replacement is needed to fix the problem, but before you replace your hardware, you should use the Windows Memory Diagnostic tool. This tool is available in both Windows Vista and 7.

Windows 7 Shut Down Faster

As you install programs on your computer, it slows down — we all know that. However, what you may not know is that the programs install services. Windows is “kind” enough to patiently wait for these services to stop when you shut down your computer; however, if you have all your work saved, there is no need to wait.

Speed up External Hard Drives

The default setting in Windows 7 disables write caching for external drives. This is done so that you can remove an external drive at any time without data loss. If you are willing to eject your drive each time using Safely Remove Hardware, you can increase the performance of your external hard drives by enabling write caching.


Enhance SATA Disk Performance

You can improve the performance of your SATA hard drive by enhancing write caching. If you are not sure whether or not you have an SATA drive in your computer, please check with your manufacturer. A quick warning: If you turn this setting on and your computer is not connected to a battery backup, losing power increases you risk of data loss or corruption. If you are using a laptop, the chances of this are unlikely as you have a battery in the laptop that will act as a power source if there is an outage.


Windows Performance Rating Tool

Like Windows Vista, Windows 7 comes with a performance rating tool, which rates your system and then gives you tips on improving it. In this section, you’ll learn how to use Windows 7’s Performance Information Tools to rate your system.

Use Startup Delayer to Reduce Boot Time

Some programs need to start right away, like your dock or your antivirus program. Some programs can wait; for example: Messenger programs, etc.

With StartUp Delayer, you can set programs to start up in defined intervals, which will smooth the startup process considerably. The program also acts as a startup manager, allowing you to uncheck programs you don’t want to run at all.

Reduce Boot Time Windows 7

Does your computer boot slowly? If you shut your computer down regularly, this can be a real pain. Anything more than about 45 seconds tests my patience and I’ve used computers that take well over five minutes to boot (really, not kidding.)

There are three easy things you can do to improve boot time:

• Remove unnecessary startup programs.
• Delay non-essential programs on startup.
• Remove Spyware.

Increase Performance Windows 7

Windows runs pretty well on its own. I am very impressed by how well Windows 7 works out of the box, but there are still a few things you can do to improve performance. In here I will focus on the key things you can do to get the most performance out of doing the least work.


As always, I recommend you make backups before making major changes to your system.

To enable options, double click on the specified option in the right-hand pane, and change the setting to Enabled (below):


Access the Group Policy Editor

Access the Group Policy Editor :

Click the Start button, type gpedit.msc, and press Enter


Group Policy Editor

Group Policy is a feature of Microsoft Windows that provides centralized management and configuration for your computer or computers in a domain. This tool is mainly used by systems administrators to control a group of PCs; however, you can use it to customize your personal machine.

Using Windows XP Mode

After you have prepared your computer to use Windows XP mode, the first thing you need to do is install your Windows XP programs. To install them in Windows XP Mode, begin by starting Virtual Windows XP from the Start menu. A Virtual Windows XP window appears, displaying a desktop for the Windows XP operating system. You install your programs just as you normally would on a computer using Windows XP; you can download software from the Web, use CDs or DVDs, or access it from a network. After you install your Windows XP programs, you can run them in Seamless or Desktop mode. Seamless mode allows you start your Windows XP programs directly from the Windows 7 Start menu, while Desktop modes opens in a separate window (Virtual Windows XP) where you can start your Windows XP programs from the Start menu.

While you run Windows XP Mode, you can share drives, USB devices, Clipboard,and printers. This means you can cut, copy,and paste data between Windows 7 and Virtual PC and use file and printing resources.

Install and Use Virtual XP Mode

To enable and use Virtual XP mode, first check for compatibility, with SecurAble, or you’ll be presented with the error below:




Requirements for XP mode (Windows 7)

Requirements for XP mode:

• Check for compatibility with SecurAble.
• 1 GHz 32-bit / 64-bit processor required.
• Memory (RAM) – 1.25 GB required, 2 GB memory recommended.
• Recommended 15 GB hard disk space per virtual Windows environment.
• NB: Windows XP Mode is only available in Windows 7 Enterprise, Windows 7 Professional, and Windows 7 Ultimate.

Windows 7 - XP Mode

Windows XP Mode for Windows 7 allows you to install and run your Windows XP programs directly from Windows 7. Windows XP Mode uses Windows Virtual PC software to provide a virtual Windows XP environment for Windows 7 Professional, Ultimate, or Enterprise users. This allows you the flexibility to run many older programs. After you install your Windows XP programs, you can access them just as you would any other Windows 7 program.

Geographic Location

Many programs in Windows 7, such as Firefox, will utilize your geographic location. This location will be used in a variety of ways including letting people know where you are when you send emails and take pictures, etc.

To set your default geographic location:

1. Click the Start button, type loc, and click on Default Location.

2. From this screen, you can set your default location settings.



3. When you are done, click Apply. Now you are ready for maximum utilization as more location-aware programs and services are released.
