Windows 7 installation tutorial
Backup
You may be installing Windows 7 on a machine that already has an operating system installed. In that case, you
will have to consider what to do with existing data on the disk.
You may want to completely wipe the existing data and start clean. Or you may want to incorporate Windows 7 into the existing setup, whether as a side-by-side installation or an upgrade.Whatever you choose, please make sure your files are safely backed up, so that you do not accidentally, irrecoverably overwrite critical data during the installation.
Installation key
Please make sure you have the Windows 7 installation key available. Without it, you will not be able to install
the operating system.
Drivers for the computer hardware
There is no guarantee that Windows 7 built-in set of drivers will include your specific hardware. Therefore,
please make sure you have the right drivers available before you start the installation. The drivers usually
come on CD/DVDs supplied by the manufacturer with newly purchased hardware. Alternatively, you may also
download them from official vendor websites.
Having the drivers available will make sure that after you have installed Windows 7, your system will perform to its fullest. If you meet the above three requirements, we are ready to go.
Boot from Windows 7 DVD
The first step is to place your Windows 7 DVD into the DVD tray and boot the machine. Your computer needs to be configured to boot from DVD. This is done via BIOS. On most computers, the BIOS menu can be accessed by pressing either the F2 or Del keys while the machine is booting.Once you have completed this stage, Windows 7 will start loading. If you see the below image, you're doing well so far.
After a few moments, you will reach the installation menu. Your first step is to choose the language and the keyboard.
You will be now taken to the Install now menu. We have already prepared for the installation, so you can click Install now and proceed.
The next step is to accept the license agreement.
After this, you will have to decide whether you want to Upgrade an existing installation or perform a Custom (advanced) installation, which is basically creating a new copy of Windows.
We will discuss multiple boots in a separate tutorial. For now, if you are interested, you may want to explore a Dual boot tutorial that tackles this issue from the Linux side, with a Linux distribution being installed alongside Windows XP. In the soon-to-come multiple-boot tutorial, I will address the installation of Windows 7 alongside other Windows (XP and 7), as well as Linux.
Partitioning
The next step is to choose where you want to install Windows 7. This is probably the most important part of the entire installation, so you need to be very careful here and make the right choices.We only have a 20GB unallocated space on our disk, so we have no dilemma. However, it is possible that you may have other partitions from previous installations present, or you may have created a custom partitioning setup before starting Windows 7 installation using a third-party partitioning software, like GParted. We will soon this discuss in greater detail. For now, let us create our Windows 7 partitions.
Inexperienced users can simply highlight the unallocated space and click Next. The partitioning layout will be created for them. However, we want to explore additional features. To this end, we need to expand the Drive options (advanced).
You now have the option to create new partitions, format them with a desired filesystem, change the size of existing or newly created partition (Extend), or delete them. The Load Driver function is usually necessary if you want to create more complex setups like RAID, but this is currently beyond the scope of this tutorial.
We will create a new partition. According to official system requirements, Windows 7 needs 16GB of free space. However, you can do with less. The minimum recommended space for a partition where you want to place Windows 7 is 10350MB. Eventually, the installation itself will take approx. 7GB.
Just for your information, here's a snippet of what would happen if you try to install Windows 7 on a partition that does not meet the minimum expected size limit:
This does not mean your installation won't succeed. It might, but why risk it?
Windows 7 installer will now tell you that it will have to create an additional partition for the core system files. This will be a small primary partition ahead of your newly created one.
This is what it looks like:
Important technical bits to pay attention to!
We now have a system partition and a primary partition, plus some free space. In purely technical terms, there
is no such thing as a partition of the type system. There are only two types of partitions: primary and logical. The above-mentioned partition is a primary
partition.
In total, there can only be up to four primary partitions on any physical disk. Windows 7, by itself, creates and uses at least two primary partitions. If we created another partition in the free space, it would too, become a primary partition.
Some quick math, this means that if we want to have more than two Windows 7 installations side by side, we don't have enough partitions available.
Recommendation:
Use a third-party partitioning tool to create a partition layout beforehand. This will allow you to place
Windows 7 files on a logical partition, saving yourself the precious commodity of wasting primary partitions on
what is essentially non-system data. We will see this example in a separate tutorial.
Begin installation
If you're comfortable with your setup, highlight the created partition and click Next. Windows 7 will be installed to this partition. Depending on your hardware, this can take some time. My testing shows approx. 30-40 minutes.During the installation, your computer may restart several times. Let it be.
User settings
Eventually, you will be asked to provide your username and a computer name. You will also have to password-protect your account. This is most advisable. You should opt for a strong password.Activation
The next step is to activate your Windows. Grab your key and type it here.Updates
You will be asked to configure your updates. You can choose either setting you like. However, I recommend you configure this choice later, after Windows 7 is installed and running properly.We will discuss this separately in the Windows 7 security tutorial. Therefore, I will choose Ask me later, but you may want to go for either the first or the second option, as you see fit.
Time zone
Configure your time zone:Location
Your location will determine the firewall settings for your newly installed Windows 7. You have three choices: home, work or public network. Home and work networks are supposed to be trusted, so you should not experience any problems adding other machines to your group or sharing data with them.However, the public network is meant to be untrusted. So if you have installed Windows 7 in, let's say, Internet cafe, then you should choose the third option.
Congratulations!
Congratulations, you have just successfully installed Windows 7.Monday, January 28, 2013

Windows 8
Windows 8 is the current release of the Windows operating system, produced by Microsoft for use on personal computers, including home and business desktops, laptops, tablets, and home theater PCs. Development of Windows 8 started before the release of its predecessor, Windows 7, in 2009. Its existence was first announced at CES 2011, and followed by the release of three pre-release versions from September 2011 to May 2012. The operating system was released to manufacturing on August 1, 2012, and was released for general availability on October 26, 2012.
Windows 8 introduces significant changes to the operating system's platform, primarily focused towards improving its user experience on mobile devices such as tablets to rival other mobile operating systems like Android and Apple's iOS.Windows 8 introduces a new touch-friendly shell and user interface based on Microsoft's "Metro" design language, featuring a new Start screen with a grid of dynamically updating tiles that represent applications. The Start screen replaces the "Start menu" of earlier Windows versions. There is a new app platform with an emphasis on touchscreen input, and the new Windows Store to obtain and/or purchase applications to run on the operating system.
In addition, Windows 8 takes advantage of new or emerging technologies like USB 3.0, 4Kn Advanced Format, near field communications, cloud computing, and the low-power ARM architecture. It includes new security features such as malware filtering, built-in antivirus capabilities, a new installation process optimized for digital distribution, and support for secure boot (a UEFI feature which allows operating systems to be digitally signed to prevent malware from altering the boot process). Synchronization of certain apps and settings between multiple devices is supported.
Windows 8 was released to mixed reception. Although reaction towards its performance improvements, security enhancements, and improved support for touchscreen devices was positive, the new user interface of the operating system has been widely criticized for being confusing and having a steep learning curve (especially when used with a keyboard and mouse instead of a touchscreen). Despite these shortcomings, 60 million Windows 8 licenses have been sold through January 2013, This includes upgrades and sell in to OEMs for new PCs.
Windows Explorer, which has been renamed File Explorer, now includes a ribbon in place of the command bar. File operation dialog boxes have been updated to provide more detailed statistics, the ability to pause file transfers, and improvements in the ability to manage conflicts when copying files. A new "File History" function allows incremental revisions of files to be backed up to and restored from a secondary storage device, while Storage Spaces allows users to combine different sized hard disks into virtual drives and specify mirroring, parity, or no redundancy on a folder-by-folder basis.
Task Manager has also been redesigned, including a new processes tab with the option to display fewer or more details of running applications and background processes, a heat map using different colors indicating the level of resource usage, network and disk counters, grouping by process type (e.g. applications, background processes and Windows processes), friendly names for processes and a new option which allows users to search the web to find information about obscure processes. Additionally, the Blue Screen of Death has been updated with a simpler and modern design with less technical information displayed.

New and changed features
Main article: Features new to Windows 8
New features and functionality in Windows 8 include a faster startup through UEFI integration and the new "Hybrid Boot" mode (which hibernates the Windows kernel on shutdown to speed up the subsequent boot), a new lock screen with a clock and notifications, and the ability for enterprise users to create live USB versions of Windows (known as Windows To Go). Windows 8 also adds native support for USB 3.0 devices, which allow for faster data transfers and improved power management with compatible devices, and 4Kn Advanced Format support, as well as support for near field communication to facilitate sharing and communication between devices.Windows Explorer, which has been renamed File Explorer, now includes a ribbon in place of the command bar. File operation dialog boxes have been updated to provide more detailed statistics, the ability to pause file transfers, and improvements in the ability to manage conflicts when copying files. A new "File History" function allows incremental revisions of files to be backed up to and restored from a secondary storage device, while Storage Spaces allows users to combine different sized hard disks into virtual drives and specify mirroring, parity, or no redundancy on a folder-by-folder basis.
Task Manager has also been redesigned, including a new processes tab with the option to display fewer or more details of running applications and background processes, a heat map using different colors indicating the level of resource usage, network and disk counters, grouping by process type (e.g. applications, background processes and Windows processes), friendly names for processes and a new option which allows users to search the web to find information about obscure processes. Additionally, the Blue Screen of Death has been updated with a simpler and modern design with less technical information displayed.
Safety and security
Additional security features in Windows 8 include two new authentication methods tailored towards touchscreens (PINs and picture passwords), the addition of antivirus capabilities to Windows Defender (bringing it in parity with Microsoft's Security Essentials software) SmartScreen filtering integrated into the desktop, and support for the "Secure Boot" functionality on UEFI systems to protect against malware infecting the boot process. Parental controls are offered through the integrated Family Safety software, which allows parents to monitor and control their children's activities on a device with activity reports and safety controls. Windows 8 also provides integrated system recovery through the new "Refresh" and "Reset" functions. Windows 8's first security patches would be released on November 13, 2012; it would contain three critical (most severe as per Microsoft) fixes.Hardware requirements
PCs
The minimum system requirements for Windows 8 are slightly higher than those of Windows 7. Notably, Windows 8 now requires that a system's CPU support certain hardware features, specifically the PAE, NX bit, and SSE2. Windows Store apps require a screen resolution of 1024×768 or higher to run, while a screen resolution of 1366×768 or higher is required to use the snapping functionality for apps.| Criteria | Minimum | Recommended | ||
|---|---|---|---|---|
| Processor | 1 GHz clock rate IA-32 or x64 architecture Support for PAE, NX and SSE2 |
x64 architecture Second Level Address Translation (SLAT) support |

|||
| Other | USB 3.0 port UEFI v2.3.1 Errata B with Microsoft Windows Certification Authority in its database Trusted Platform Module (TPM) Internet connectivity |
Tablets and convertibles
Microsoft released minimum hardware requirements for new tablet and convertible devices designed for Windows 8, and defined a convertible form factor as a standalone device that combines the PC, display and rechargeable power source with a mechanically attached keyboard and pointing device in a single chassis. A convertible can be transformed into a tablet where the attached input devices are hidden or removed leaving the display as the only input mechanism.| Graphics Card | DirectX 10 graphics device with WDDM 1.2 or higher driver |
|---|---|
| Storage | 10 GB free space, after the out-of-box experience completes |
| Standard buttons | 'Power', 'Rotation lock', 'Windows Key', 'Volume-up', 'Volume-down' |
| Screen | Touch screen supporting a minimum of 5-point digitizers and resolution of at least 1366x768. The physical dimensions of the display panel must match the aspect ratio of the native resolution. The native resolution of the panel can be greater than 1366 (horizontally) and 768 (vertically). Minimum native color depth is 32-bits. |
| Camera | Minimum 720p |
| Ambient light sensor | 1–30k lux capable with dynamic range of 5–60k |
| Accelerometer | 3 axes with data rates at or above 50 Hz |
| USB 2.0 | At least one controller and exposed port. |

Brontok virus
Brontok virus is also called :
W32/Rontokbro.gen@MM, W32.Rontokbro@mm, BackDoor.Generic.1138, W32/Korbo-B, Worm/Brontok.a, Win32.Brontok.A@mm, Worm.Mytob.GH, W32/Brontok.C.worm, and Win32/Brontok.E, W32.Rontokbro.D@mm., I-Worm.VB.DV,opopopopo, about.Brontok.a, W32.Brontok.a
When Brontok is first run, it copies itself to the user's application data directory. And then he sets itself to start up with Windows. It disables windows regedit.exe (registry editor) and he also turn off firewall.
Removing Brontok!!
Brontok removal tool. Free and secure download link.
Or follow these stepes.
Boot your laptop/pc into Safe Mode. (Start tapping the F8 key as soon as the computer starts displaying the initial startup gobbledygook. At the options, choose Safe Mode WITHOUT network support.) Sorry if you already know this, but Safe Mode boots the computer with as few components as necessary. Many viruses and spyware hide in the extras, making them basically impossible to get rid of in regular mode.
Now insert your Brontok washer floppy and run it. When it's down, do a complete shutdown of the laptop/pc (not a restart.) Boot the laptop back into Safe Mode with no networks and check to be sure Brontok is gone. You may have to run it a few times to get everything completely cleaned off.
Still in Safe Mode no Networking, install Spybot S&D and run it as well until it reads clear, closing the laptop down completely at each go. Spybot S&D is my favourite spyware blocker-scanner.
Also i strongly recommend use Malwarebytes Anti-Malware instead of Spybot SD but that's only how i do it.
Finally, when Spybot S&D says you're clean, boot your laptop in regular mode and install Crap Cleaner. Crap Cleaner cleans up all the crap Micro$uck..er..soft leaves in the registry. When you open CC, click on the issues button and have it scan. Again, it will take a few runs to get your laptop cleaned up, but with CC, you don't have to do complete shutdowns.
There is some free download links to help you in process :
Spybot S&D
malwarebytes anti-malware
Thx to tbbrick for nice explanation for this problem.
