Cloud computing is basically using resources either software or hardware that are in a different location(the cloud). The term cloud comes from when the internet is drawn in a technical diagram it is usually represented by a picture of a cloud. That means that you may login to a remote server to do your computing that means that any computer could essentially become your work computer with a simple login. There is also cloud storage, meaning that your data is stored in another location and then either synced to your device or accessed on demand.
The Windows 8 cloud
Windows 8 has cloud storage built into it using Microsoft’s Skydrive. Skydrive is a cloud storage platform that stores your data on Microsoft’s servers somewhere so you can access it on multiple platforms and wherever you go. Skydrive my be windows 8’s built in cloud storage but there are other options out there such as dropbox and google cloud storage. With skydrive integrated into the windows 8 platform it makes it quite easy to have your essential data on Microsoft’s cloud. Windows 8 will automatically sync any information that you place in the skydrive folder to the Microsoft cloud. So now you can write a word document on your desktop and then save it to your sky drive or other cloud storage service and then on the train you might remember you missed something so you access it on your phone and add what was missing save it back to the cloud and then when you get home that same copy has been changed to how you needed it to be.
Windows 8 also can sync your personal user preferences to the cloud so any Windows 8 device will pull information down from the Microsoft cloud and have the same theme and look as all of your other windows 8 devices. This makes it very easy to go from a Windows 8 desktop to a Windows RT tablet and also to the Windows 8 phone.
Many of the Windows 8 apps also use the cloud in one way or another whether it be by using processing power of a server instead of using your device or they may use the cloud to store the information relevant to you,
Active Directory or AD is a role that you can install on windows server to promote it to a domain controller and manage your domain.
AD has been designed by Microsoft to manage your domain. AD stores user, network and domain information in a single jet database and can manage the security surrounding all that information. Active directory is used by system administrators to control access to domain systems and also information and the way users interact with the system. Active directory was introduced in the 90’s by Microsoft to improve the windows NT flat domain model that was not scalable enough for larger domains. They based Active Directory on LDAP(lightweight directory access protocol), which is a protocol developed by the university of Michigan.
AD stores information on users such as first name, last name, address, phone numbers etc. for use by other applications and services like Microsoft Exchange(emails) and uniflow(canon print management system). Active Directory also stores information about computers, printers, services security permissions, domains, people and more. All of this information is then integrated to be used in the active directory environment.
With Active Directory you can group your computers and your users int o different groups to give them different security levels and system options like you may want only people in the finance department to be able to view the finance shared folder so you would add all of your finance department employees to a group and give that group permission to view the finance share.
Active Directory users are controlled by something called group policy. Group policy is a set of rules that the user must abide by eg. Password complexity, blocking task manager or using a certain printer. Group policy can contain multiple rule sets called Group Policy Objects or GPO’s and they can be mapped to correspond with different groups, you may have multiple GPO’s applying to one group and multiple groups using the same GPO’s.
Today you will be learning how to connect to the internet through your ADSL router or modem.
What you will need
Internet connection and details from ISP(internet services provider)
Make sure that your internet provider has told you that the internet has been connected. Sometimes it can take a couple of weeks to happen.
So you have all the information from your ISP? On it there should be a user name and password, vpi and vpc, encapsulation and multplexing. All of this information is needed for your connection to be established if there is a typo your internet will not connect so make sure everything is typed in correctly.
Always remember to press the save button before navigating away from a page in the router console as routers will forget what has been put into them unless it has been saved.
You will neet to connect your router/modem to a computer and into the phone line. make sure that the phone line is connected into the right port, the phone line port will be smaller then the computer port.
Power on the router, make sure that the lights on it are lit up and that the light for line is also lit(that indicates it is connected to the phone line)
Go on the computer/laptop that you have connected to the router bad make sure that it is configured to obtain an IP address automatically.
Go to command prompt and type in “ipconfig /all” this will give you your ip information. Find default gateway of local area connection. Note down the number.
Open an internet browser and type in the default gateway address (the number that you noted down) and press enter. This will direct you to the router.
Type in the username and password. If you dont know it it will most likely be the default username and password for your router, this will be on the paperwork that you recieved when you bought your router. If you do not have the paperwork then you can look them up on http://www.routerpasswords.com/.
Now you will be inside your router console you need to enter all of the details into here in the fields that correspond with the details that you have got from your ISP. Then make sure you save your internet connection settings or you will lose them when you navigate away from the page.
Find the test connection button and test your internet connection. If everything is set correctly then it will tell you it is s success.
If this returns a failure then ‘re-enter your internet settings and test again, if it still does work that’s when I would contact the internet service provider and get them to help you (don’t feel bad about ringing them that is what they are paid to do)
Most modern routers will have settings by default to automatically dial the internet connection(or connect to internet automatically) but you still should look for this setting and set your router to automatically connect. Make sure you save your settings.
Now you are connected to the internet and you should be able to browse the internet through your browser, so go ahead and look up heresjaken and all of your other favorite websites.
People often ask me to remove their viruses from there computer and i charge them for my time, which is fair enough, but why would you want to pay someone to do something you can do for free yourself. When I remove my friends viruses I show them how to do it themselves and they are usually surprised at how simple it is. I have decided to make this little tutorial to show you all how to kill your own viruses.
So your computer is doing weird stuff and you think you might have been infected. What do o you do now? Well there are two options. First you can pay anywhere from $50 to $200 to get someone to fix it, or you can do it yourself at home for nothing using the exact same virus removal tools they use.
You will need:
A backup drive(optional): to back up your data.
RKill: This stops any suspicious processes that your computer has running
CCleaner: To clean your registry after the virus removal process
Malwarebytes: This is the actual virus removal tool to run a virus scan and remove the detected files
Combofix: This is a last resort, it is a dangerous program to use because it can make low level changes to your operating system and render it unusable.
All of these programs are free!! The only thing that will cost you money is the backup drive. The backup drive is optional but i recommend it because sometimes the virus may have adverse effects on your data during the removal stage or even while it is infected. Always make sure you update your virus removal programs before use.
Boot to safe mode. You do this by powering on your computer and repeatedly pressing the “F8” key until the boot menu is opened. You want to select “Safe mode with networking” as we will need to update the virus removal software once it is started.
You may also want to back up your outlook data if you have e-mails coming through outlook. Outlook Data is located at “drive:\Users\user\AppData\Local\Microsoft\Outlook” in windows Vista , 7 and 8. In XP it is stored at “rive:\Documents and Settings\user\Local Settings\Application Data\Microsoft\Outlook”.
Download and run RKill, when you download it make sure you download the one marked iexplorer.exe and run that. The name of the program has been changed so malware does not know what it is and stop it from running.
Download and install Malwarebytes. At the end of the installation it will ask you if you want to enable a trial of Malwarebytes Pro, uncheck this box as we do not need it leave the other boxes checked that say to run on completion and to update the program.
Run Malwarebytes and do a full scan on all drives that are showing. This may take anywhere from an hour to all day so you might as well take a break. Have a coffee or a beer maybe…
At the end of the scan Malwarebytes will give you the results of the malware scan. I recommend removing all of them. But you may not want to because it can show some useful utilities as hack-tools or suspicious files. If your not sure then just select clean all. Once all of the viruses are removed it will prompt you to restart your computer, you definitely want to do this as some viruses may hide in your RAM and re-install themselves without you knowing.
Once your PC you will need to run Kaspersky TDS Killer. This will do another scan but inside of your system files. TDS Killer looks for root-kits which hide themselves as part of your operating system. If the scan from TDS Killer finds anything remove it. Hopefully it wont.
Now we use CCleaner to clean out the registry. This will remove any keys that point to not existent files, keys that have duplicates and also keys that your virus may have left behind.
Now it is time to test your computer, just do some normal things on it like browse the internet and what ever else you feel like doing on it. If you go to 3 minutes and 10 seconds on the video below it will show you how to clean out the registry. Always make sure you save a backup copy of the registry in case the program accidentally deletes something it wasn’t meant to then you can go through and restore the registry to a previous state.
If you still have problems…
So you still have problems??
That is not good. This means you will need to bring in the big guns.
WARNING: Combofix makes low level changes to your operating system. This is a utility that can leave your computer inoperable
Now we run Combofix. This anti root-kit utility may reboot your computer a few times while it runs. Once it has finished it will show a report outlining the changes that have been made. After running Combofix to remove your virus or root-kit you will want to run CCleaner to clean the registry again.
If you still have problems you most likely need to re-install your operating system or take it to a professional.
Now there are a lot of different versions of windows 8 and you may be wondering what they all mean. There are all the different builds and there is also ones called Windows 8, Windows 8 pro and Windows 8 enterprise. Well here is a list of them.
Windows 8 is the basic edition of Windows for the x86(32 bit) and x86-64(64 bit) architectures. This edition is also referred to as Windows 8 core edition. This edition contains features aimed at the home user and provides all of the basic new Windows 8 features including the Start screen with semantic zoom, live tiles, Windows Store, Internet Explorer 10, connected standby, Microsoft account integration, the Windows desktop and more.
Windows 8 Pro
Windows 8 Pro is comparable to Windows 7 Professional and Ultimate. This edition is more targeted towards enthusiasts and business users, it includes all the features of Windows 8 but add more features such as the ability to receive Remote Desktop connections, you can join a Windows Server domain, Encrypting File System, Hyper-V, and Virtual Hard Disk Booting, Group Policy as well as BitLocker and BitLocker To Go. Windows Media Center functionality is also available but is an additional software feature that needs to be purchased.
Windows 8 Enterprise
Windows 8 Enterprise provides all the features in Windows 8 Pro (except the ability to install the Windows Media Center add-on), with additional features to assist with IT organization such as AppLocker. This edition is available to Software Assurance customers, as well as MSDN and Technet Professional subscribers. For the regular user there is no point getting this version as it is aimed at enterprise level organizations.
Windows RT will only be available per-installed on ARM-based devices such as tablet PCs. It includes touch-optimized desktop versions of the basic set of Office 2013 applications to users—Microsoft Word, Excel, PowerPoint, and OneNote, and support device encryption capabilities. Several business-focused features such as Group Policy and domain support are not included.Normal programs able to run on windows will not run on Windows RT because of the different processor that it runs on.
Windows Release Preview
This is the same as the release candidate. This is a free demo copy.
Windows Consumer Preview
This was release before the release preview. This version is a free demo copy. Has more bugs that have not been worked out and does not have full functionality of the release preview.
A graphics card or GPU(Graphics processing unit) is a card that will plug into an expansion slot on your mother-board. The GPU is an additional processor that takes care of the calculations that generate the picture you see on your screen. The GPU takes the load off of the CPU so it has more power to use for other functions. The graphics card will often have multiple cores on its processing unit and also have its own on board RAM. The use of a graphics card can increase speed of you system and is often needed for playing games with high intensity graphics.
How to choose your graphics card?
You need to know what you intend to do with your computer, if you just want to use it to do internet browsing and writing word documents and email than the card that is built into your motherboard should suffice. If you want to play games with high intensive graphics or do video editing this is when you would want to look into getting a GPU. All this being said how do you know which one to get? There are thousands on the market starting from as little as $40 all the way to $600+.
There are sites out there like Video Card Benchmark out there that have benchmark scores of many different GPU’s to compare, basically the higher the score the better the card.
But still how do you know how much power you need in your card. Well once you know what you intend to do with your computer and what you intend to run on there, do some research. Look up the requirements and recommended hardware for the software you want to use and then base your needs off that. I always go extra then what the site says because you want it to run smoothly and not put to much stress on your system. You can also check out forums, Yahoo answers has a lot of information, many people have asked questions about them. Don’t take anything as 100% correct, make sure you find more than one source for your information because somebody could just be trolling you and telling you to get a shit one just for a laugh.
This is a video demonstrating how to install Windows 8 Pro. When installing any of the other versions of windows 8 you go through the same process.
I honestly found it more enjoying then previous windows installations, they have more pretty colours and stuff and give you a tiny bit of information on how to use it. Still no where near as entertaining as an Ubuntu installation but, oh well…
