Install Windows 7, 2008, 2008R2, 8, 2012 from USB

This is a quick how-to on installing Windows 7, Server 2008/R2, Windows 8 and Server 2010 using a USB flash drive. The reason I do this is because of the speed and not having to use, or be bothered with burning a DVD.

I will give you the steps I have taken along with some of the requirements.
First and most important; What you will need.

1. You will need a 4GB USB Flash Drive – I recommend using 8, this way you can load extra software installs, drivers etc.
2. You will need the installation media from Windows 7/8, Server 2008/R2 or Windows 2012.

Now for some simple fun – Rather than take you down the path of how to copy the files to the CD and set it to active and assign it a partition etc.  I am going to point you to some useful tools.

1. The Microsoft Windows 7 USB/DVD download tool – And this works for all the Operating Systems I listed above.  Its simple to use and 99% error proof.  Best of all this is supported by Microsoft.  You can obtain this tool here.
 2. Another tool of choice by me is the Universal USB Installer, I often use this to create live boot USB images for running things like Backtrack or Ubuntu. Also like that of Windows it allows me to have installation media without the need of a CD/DVD. The team over at pendrivelinux have done a wonderful job so I also recommend using this tool. You can download it here

If you as me, both tools has it place in my tool kit, so feel free to use which ever works best for you.  I hope this quick post was helpful.

SkyDrive for Windows and Mac

SkyDrive is back, and full integration in Windows and Mac

SkyDrive for Windows is the easiest way to access your SkyDrive from your PC. When you install SkyDrive, a SkyDrive folder is created on your PC. Everything you put in this folder is automatically kept in sync between your computers (PC or Mac) and SkyDrive.com, so you can get to your latest files from virtually anywhere. Whenever you add, change, or delete files in one location, all the other locations will be updated.

If you forgot to put something in your SkyDrive folder, you can still get back to your PC to access all its files and folders from SkyDrive.com

Windows Server 8 named Windows Server 2012

A few days ago Microsoft has announced that the Windows Server 8 will be named Windows Server 2012.

This was made known at MMS (Microsoft Management Summit) on April 17, 2012.  I just found out about it myself.  Not a big shocker for me.  I just wanted to share the news and keep the cycle of informaiton flowing

My thoughts on how to keep your data safe

I think that data security should be one of the top concerns for computer users. If your computer is stolen, often the impact of confidential or proprietary data being lost or compromised can be much higher than the cost of replacing computer itself.

There are many easy ways of keeping your data out of the wrong hands

Login Passwords

A login password consisting of a username and password to login to ones computer is the most basic security methods used today to gain access to a computer. But what about a shared computer systems others may have access to your data, especially anyone with an administrator account on the system

A login password does not protect data.  Your hard drive cans still be accessed and its as simple and pulling the drive out and hooking it up to a USB cable on another system.  And with advancement in tech. The thief can boot your system from a Live CD or USB thumb drive and get full access to your data.   It’s that simple.

Okay, so I will now enable a BIOS password.

BIOS Passwords

A BIOS system password prevents the system from booting ANY device without the correct password. It protects the physical system from being used, and goes a step beyond the login password above, by preventing the system from booting any attached drive (including removable ones). However, it’s still easy to defeat on desktop systems — a motherboard jumper can clear the password. Again, a BIOS password doesn’t protect the physical data on the hard drive — the drive can be put in a different machine and accessed.

What about hard drive passwords?  This is the next step, but not the last on my list of what to do

Hard Drive Passwords

A hard drive password or “hard drive lock” will cause the drive to not work until the correct password is entered. This follows the drive even if it’s removed from the system, and provides a level of security against a good number of would-be data thieves.

The drive can’t be used or reformatted. However, its not encryption — it’s read/write protection, and tools exist to remove it.  tools can be found here and my best set of all around tools here

I have had an hard time hard disk passwords in my day.  Especially when I set a hard drive down for a long period of time and can no longer remember the password.  This is why I choose encryption of data on disk.

Software Encryption

Encrypting the underlying data itself is one of the best ways to protect your data against compromise. AES encryption is almost unbreakable due to the theoretical limits pf an Brute-force attack. When it comes at a hit to system performance. TrueCrypt and Windows BitLocker are both great implementations of full-disk encryption software.

Closing Statement

There are many ways to protect your data and all of the above are good methods; some protection is better than none at all.  I advise you to “do the needful” and secure your system as best you can.

 

How to get your Dell Service Tag

There are those times you need the service tag from a system such as a noteboot, server, or pc and just can’t get to it.  Or… taking the “I’m not getting up for this method”.

Using the Windows Management Instrumentation Command-line (WMIC) you can pull this information right from the command prompt. Simply type the following:

wmic bios get serialnumber

You can also do something similar in Linux..  In my case I use Ubuntu and type:

dmidecode -s system-serial-number

Please note that in both systems you may need to elevate your rights to issues these commands.

Test your anti-virus product

I was thinking tonight about anti-virus programs used today.  And with the many malware attacks that aim to cripple your anti-virus solution, how can one test if its working or not.

To get past that fale sense of security; because what we don’t know will hurt us.  That said I suggest using a test virus (known virus saved on a CD or USB, or using the EICAR anti-virus test file

The EICAR Standard Anti-Virus Test File is a non-destructive test file that was developed for this purpose: To safely test anti-virus programs for proper operation, without having to actually expose the system to a destructive program. All anti-virus programs should detect to, and respond to, EICAR as a virus. However, is it not malicious.

You can download the EICAR test file directly from EICAR here and run it. Your anti-virus should immediately react.

You can also just create a new txt file with the following EICAR test string:

X5O!P%@AP[4PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*

Here is a screen cap of my test results:

Dynamic IP Restrictions in IIS7

The Dynamic IP Restrictions Extension for IIS provides IT Professionals and Hosters a configurable module that helps mitigate or block Denial of Service Attacks or cracking of passwords through brute-force by temporarily blocking Internet Protocol (IP) addresses of HTTP clients who follow a pattern that could be conducive to one of such attacks. This module can be configured such that the analysis and blocking could be done at the Web Server or the Web Site level. The module includes the following features:

  • Seamless integration into IIS 7.0 Manager.
  • Dynamically blocking of requests from IP address based on either of the following criteria:
    • The number of concurrent requests.
    • The number of requests over a period of time.
  • Blocking of requests can be configured at either site or server level.
  • Configurable deny actions allows IT Administrators to specify what response would be returned to the client. The module support return status codes 401, 403, 404 or blocking the requests entirely.
  • Support for IPv6 addresses.
  • Support for web servers behind a proxy or firewall.

2 Skype’s 1 Computer

For those of you who understand the topic reference.
Shame on you.

Doing some digging on how this would work i came across the following help document from our friends over at Skype (now, Microsoft) on how to run multiple Skype clients on a single desktop session. The procedure was shockingly simple to do.

From the Windows taskbar, click Start > Run

In the Run window, enter the following command (include quotes) and press OK

“C:Program Files (x86)SkypePhoneSkype.exe” /username:jermsmit /password:myspassword /secondary

As you notice you can add this to a batch file and give it the Skype icon and in a single click run to at once, or even just run each as needed.

Batch file would look something like this:

start /D “%ProgramFiles(x86)%SkypePhone” Skype.exe /username:jermsmit /password:mypassword /secondary
exit

 

Note: Please adjust your environment variables for your OS type

32 Bit:  %ProgramFiles%

64 bit: %ProgramFiles(x86)%

 

Enjoy running both your personal Skype along side the one you use at work.
