Security in Microsoft Windows 7's

Windows 7 security is the top most dominating feature, which has raised the global demand of its installation. There are plenty of new features along with some good modification in the previous features and the operating system offers enhanced security for both online and offline activities.

Microsoft has blessed its new operating systemwith some innovative features, such as DirectAccess, Biometric Security, Applocker, Windows Filtering Platform (WFP). Besides, there has been a considerable improvement in previous features, like Windows Secuirty Center of Vista has been presented in a more effective way as Action Center, BitLocker has been revised to perform advanced job.

With the modified and innovative features, like BitLocker, you can share your data with your colleague without any worry, DirectAccess helps to share your office network in a secure manner, when you are on move. With Action Center, you can troubleshoot the problems arising with software and hardware conflicts in a much better way. BitLocker feature, which is useful for encrypting your data files, is not available with the Windows 7 Home Premium Edition. It has been observed that the files encrypted are hard to recover, in case of any data loss.

Windows 7 Firewall has been modified to a great extent, now it can filter both inbound and outbound traffic of your computer's network. Windows Defender can be customized well, under the Advanced Setting option, available in Control Panel, for quick, complete and partial scanning of your computer's memory. While in Vista, you were permitted for doing only basic setting. In addition to this, you can also customize it as per your need to scan public network, home network or work network. Moreover, you can perform scanning of each one at the same time, it was also restricted in earlier Vista, where you can do scanning of one network at a time. Next improvement has been done with the restriction from User Account Control, which doesn't allow others to perform any setting change over your PC in your absence.

With effective Windows Firewall, Windows Defender and software, you can keep your computer safe from viruses and ensure good performance. Adding on, you can remain free from frequent computer's issues like sluggish performance, slow startup, blue-screen error and computer's freezing. You can keep your Windows registry in sound condition, which is the God father of your computer.

Understanding the global threat about cyber-crime and other malilcious softwre, Microsoft has done a complete overhauling in the security feature of Windows 7. With the new operating system, you can share your computer's data and peripheral devices like, printers and scanners in a much secured manner.

Advantages and disadvantages are always associated with any development. There are some limitations in Windows 7 security, like Windows Firewall has been observed to be getting disabled on attack of some sophisticated viruses. Windows 7 still using the same encrypt arithmetic as the previous versions of Windows. That means that if you need to reset Windows 7 password, you can just use the similar methods like Windows Vista or XP. Sometimes you even have to use some Windows 7 password recovery software that is used for Windows 7 password reset. Further, it also raises issues while installing some new programs or making some download from any website. Windows Defender needs to be configured well after each and every new installation work you perform on your computer.

For attaining better security over your Windows 7 installed computer, you should keep your Windows update enabled, when you are online. Status of Windows Defender should be monitored on regular basis. In addition, your computer must have a compatible antivirus program.

Windows Registry Cleaners

What is Windows Registry? Why does it need cleaning?

The Windows registry is a directory which stores all the important hardware and operations settings for Microsoft Windows operating systems i.e. Windows XP, Windows Vista etc.

This registry can be corrupted over time, just by using it, and by spyware, viruses or the installing and removal of software where not all programs are removed cleanly, leaving invalid files in the registry, adware and anything else that should not be there.

The result of this is that you will find that your computer will get slower, doesn't load applications, gets computer errors, inexplicable system crashes and eventually the dreaded blue screen. This usually means your Windows registry needs cleaning.

The way to fix this is to do a Registry scan and then clean or repair your registry. This needs to be done at regular intervals. You will then find that this will speed up your computer, reduce the computer errors and keep it running smoothly.

You can edit this registry yourself but it is strongly advised that if you are not an expert then leave it alone! Careless editing can cause irreversible damage to your computer - and expensive repair bills.

The alternative, used by most people, is to use one of the several excellent registry cleaners which can be downloaded from the internet and quickly put to work cleaning your registry.

As you only need to use this a few times a year you will obviously not want to spend too much money. You can find good programs which can fix windows registry for $25 -$35 per year which is not a bad price for a clean,faster, smoother computer and peace of mind.

There are numerous registry cleaners for Windows and a search will soon show good quality registry cleaners. You need to look for a program that is backed by technical support and which puts safety first.

Most good registry cleaners will have a free trial download which will give you a "feel" for that particular piece of software.

The good cleaners all do a good job and tend to vary very little. A good piece of advice is to search for reviews and see what other people have to say.

Finally, whether the software has backup or not, it is strongly recommended that before running any registry software ,that you create a System Restore point first - just in case.

If you have not done this before this can usually quickly and easily be found via the Control Panel/Performance And Maintenance/System Restore or All Programs Menu /Accessories/System Tools/System Restore although this can vary with your version of WindowsFree Reprint Articles, country etc.

History of Computer Operating Systems - Unix

Unix like Operating Systems
We are all aware of the fact that Unix is an open source operating system. By open source, we mean that its source code is kept free for changes. No doubt, for a full version Linux, you will need to have the license key from the vendor from whom you are getting the operating system. There are various vendors like Red Hat, Fedora, etc. who design Linux operating system.

History of Computer Operating Systems - Unix
Unix operating system is designed by many vendors today. However, the success of UNIX can be many attributed to the AT&T's Bell Laboratories from where it was desiged and released in 1970's. By the end of the 1970's most people who had done pioneering work in the success of this operating system were holding important positions in the computer world. They insisted on using UNIX. Educational institutions, Government bodies and electronic companies, all continued to use Unix. This led to various vendors entering into this market and producing their own versions of Unix. In 1980, 'The Open Group' or X/Open Company Ltd. was formed by a group of vendors to limit the encroachment by larger companies who wanted to control the system interface. Open Systems had to meed specific standards and Unix system was chosen as the platform for the open systems. In 1993, AT&T sold its Unix System Laboratories to Novell and in 1995, SCO bought the same from Novell. In 1995 X/Open introduced the Unix 95 brand for computer systems. It was meant to guarantee the Single Unix specification.

Windows 7 backup

Create copies of data files and system image which includes system settings, programs and files with Windows Backup. Choose custom location in Windows 7 for data backup. You can check for this option under System and Security in your Control Panel and can also access it through Action Center.

Some vital functionality was missing in Windows Vista which Microsoft has tried to cover up in Windows 7. Windows 7 has build on the new features in Windows Vista Backup. Windows 7 provides you with in-built tool to back up your data. Microsoft has introduced consolidated Backup and restore Center in Windows Vista but Windows 7 has in-built backup center. It’s in-built “Shadow Copy” feature restores the previous versions of files and folders and makes repetitious backups when required, if certain part of the file has been changed then it only transfer that part and copy it over.

Backup and Restore Center will show you the backup device you have selected, the space left on it, the space occupied by windows Backup and how far you are into the process if you are currently running a backup. Windows 7 backup facilitates you by providing access to your previous system image files for deletion, it also displays how much space is being used by each of its backup components.

Try the following steps to create backup:

1 Start the process of creating a backup from the Backup and restore center in the Control Panel.

2 Choose the location where you want to create your backup.

3 Network location can be selected to create backup. Add your network path by clicking Add New Location.

4 Choose what to backup, once you have chosen the location.

5 You can choose your own files as well as Windows chosen file.

6 Start backup process. the Backup and Restore center notifies that backup is in progress.

7 Restore the files once backup process is over.


But it is far more easier to backup your files over the network, if you are using Professional or Ultimate edition of Windows 7 then you need not keep the drives as you also have the option of backing up your files to a network.

You can set up your network to save the copies of critical files. It will surely proved to be a worthwhile investment as a Home Network backup can easily maintain the copies of the electronic data files thus securing the data in case of theft, disaster and computer failures. You have the option to choose from online service or Home Network backup. There are different methods using which you can set your data on Home Computer Network such as backups to CD-ROM or DVD-ROM discs, network backups to a local server and online backups to a remote hosting service.

In network backup to a local server you don’t require to burn several disks considering setting up a backup server on your home network. A backup server has a large hard disk drive and network to receive other home network files. In Network backup to a Remote Hosting Service many Internet sites offer backup hosting services which results in automatic network backups.

All these features help the user to have the full control over the flies which are backed up and you can have automatic backup capability with suitable software in Local Servers Backup. In Remote Hosted Backup your data is saved with lower risk from theft.

Multilingual User Interface for Windows 7

Based on your company's current geographic and IT infrastructure, you need to determine your language and country/region requirements, as well as your hardware requirements and limitations to deploy the appropriate language configurations of Windows 7 and configure country/region support.

You will also need to:

* Determine the roaming user needs in your organization.
* Evaluate the hardware requirements for multilingual support.
* Determine whether your organization will need to deploy a single global image or specific country/region builds for different offices in your organization.

Assessing hardware requirements for multilingual support
Supporting multiple languages can impact your hardware requirements in two areas:
Hard disk space: Some languages require more hard-disk storage space than others. The more languages installed on a computer, the more hard-disk space consumed.
Specialized hardware devices: Some languages or users require special keyboards, IMEs, or alternative input devices.

Determining the requirement of language and country/region
If you have polyglot office environments or you do business in multiple languages then you need to know which languages or bids your organization requires. Also you need to know that whether these languages require input devices or input method editors (IMEs).

You must determine whether currency, time zone, or calendar formats vary between the different countries/regions if you do business on international level. Additionally, you must determine which line-of-business applications you have that must accommodate such country/region differences.

A four-column planning table can help you determine your language and country/region needs. You can organize the table as follows:

* In column one, list your offices or divisions.

* In column two, list the languages or dialects used in those offices or divisions.

* In column three, note the corresponding Windows 7 language collection and locales that support those languages or dialects. For tables listing Windows 7 language packs and settings, see Supported Language Packs and Default Settings.

* In column four, note special standards and format settings, input language support, or default languages for non-Unicode programs required for your offices or divisions.

So, as release date of Windows 7 is close, we find ourselves with revolutionary and new Microsoft OS: Windows 7. Windows 7 seems poised to succeed where Vista couldn’t as it is built on the latest technologies introduced with Vista, but with a renewed focus on performance and compatibility. We’ve finally received a final build of Windows 7 and have run it through the wringer in both the Lab and in the real-world. Here’s what we found.

Questions To Be Consider When Going for Windows 7 upgrade

Whether you’re keen to upgrade to Windows 7 or you just wish to know what to expect if and when you do, there are lots of things to keep in mind.

Can I upgrade directly from XP?
Many users who are still running Windows XP want to know whether they can upgrade to Windows 7 without losing all their data and settings. The answer is, well, sort of. Microsoft doesn’t provide a direct upgrade path from Windows XP to Windows 7. An in-place upgrade is available only if you’re running Vista SP1 or later. If you have Windows XP, even if your hardware is compatible, you’ll have to perform a clean installation of Windows 7. However, you can use the Microsoft Deployment Tool, which includes the User State Migration Tool, to transfer your user settings for the desktop and applications to the new Windows 7 installation.

Can I do a Vista in-place upgrade?
If you have Windows Vista, remember that you must install SP1 or SP2 before you can perform an in-place upgrade to Windows 7. If you try to upgrade a Vista computer that doesn’t have a service pack installed, you will get a message informing you that to upgrade to Windows 7, the computer needs to be running Vista with Service Pack 1.

Will there be driver compatibility issues?
A big problem in Windows Vista was driver incompatibility. Too many users upgraded their Windows from XP to Vista only to find that a favorite peripheral, such as a printer or scanner, would no longer work. Vista also introduced a new display driver model, WDDM, which required video card vendors to write completely different display and video miniport drivers. And security enhancements in Vista affected how the OS handles drivers. Even though Vista was in development for few years, many hardware vendors did not have Vista drivers ready for all of their products when the OS was released.

Now that Vista has been out for more than two years, most hardware vendors have updated their drivers to work with it. Because Windows 7 uses the same driver models as Vista, the vast majority of hardware devices that work with Vista will work with Windows 7. For Vista drivers that won’t install on Windows 7, you can usually solve the problem by installing in Compatibility Mode. To do this, right-click the driver’s setup file, select Properties, click the Compatibility tab, enable compatibility mode, and select the appropriate operating system from the drop-down box.

Which Windows 7 version shall I choose?
Windows 7 is also comes both Home Basic and Home Premium editions. There is also a Starter edition, which comes with low-powered netbooks.

What if I have applications that won’t run on Windows 7, even in Compatibility Mode?
There may be some XP programs that you can’t get to run on Windows 7, even using Compatibility Mode. However, you may still be able to enjoy all the benefits of Windows 7 without giving up your favorite applications, thanks to a new compatibility tool called XP Mode. XPM is a host-based virtualization solution that will reportedly be made available at no cost to users of Windows 7 Professional, Enterprise, and Ultimate editions.

Windows 7 Guide- Changes To Security in Windows 7

Microsoft launched Windows 7 with few enhancements such as HomeGroup, Aero, etc. However, there are several of new and enhanced security features as well. Here’s a rundown of key changes you must know about.

Everyone’s talking about the interface changes, the new taskbar, omission of the sidebar, a new look for Windows Explorer. Under the hood, there are few more changes, including latest and enhanced security features. Let’s look at some security features that have been changed or added in Windows 7.
Action Center- In Vista, security configurations can be access from the Security Center in Control Panel. In Windows 7, you won’t find a Security Center. That’s because it’s been replaced by a new Action Center. The Action Center offers security configurations as well as options for other administrative tasks, such as Backup, Troubleshooting And Diagnostics, and Windows Update.

Windows 7 UAC- User Account Control (UAC) was introduced with Vista, made to provide better protection from malware. It makes all user accounts run as standard users, even administrator accounts. If you need to perform something that requires administrative rights, it asks for permission. And asks. And asks. This in-your-face aspect of UAC has caused numerous complaints and has led some users to turn it off completely, thus exposing themselves to threats.
In Windows 7, UAC is still there, but now you can set up how vocal it will be. There are four settings you configure from the UAC settings in the Action Center. You can set UAC to:
• Always notify you when you install software or make any changes to Windows settings (as Vista does now).

• Notify you when programs make changes but not if you make changes to Windows settings (default Setting).

• Notify you only when programs make changes but turn off Secure Desktop, which dims the desktop while the UAC prompt is displayed. ( Preferred setting.)

• Never notify you. ( Not recommended.)
BitLocker- Windows 7 comes through and allows you to encrypt removable storage drives. And it’s easy to do. Just open the BitLocker applet in Control Panel, choose the drive you want to encrypt, and click Turn On BitLocker.

Windows Filtering Platform- Windows Filtering Platform (WFP) is a set of APIs introduced in Vista. In Windows 7, developers can use it to iinclude some parts of the Windows Firewall into their own programs. This will allow a third-party program to turn off certain parts of the Windows Firewall selectively if need be.

DNSSec- Windows 7 supports for DNSSec (Domain Name System Security), which is a group of extensions to the DNS platform that improved security. With DNSSec, a DNS zone can take advantage of digital signature technology so that you can validate the authenticity of data that’s received.
