  1. Format the Linux partitions to create unallocated space, if you haven’t already. You can find a walkthrough on how to do this under External Links listed below.
  2. Change the BIOS so that your computer boots your CD drive first.
  3. Insert the Windows XP disc and reboot. It may take a few minutes to load.
  4. Select ‘Recovery Console’ by pressing ‘r’.
  5. Select the Windows system to log on to. The default option is ‘1’.

How to Fix Win32 Generic Host Error?

June 26, 2009 1 comment

What is an Generic Host process for Win32:

Generic Host Process for Win32 Services or svchost.exe is a legal and essential component of Windows which is used to host services which run from dynamic-link libraries (DLLs). Multiple instances of Svchost.exe can run at the same time. So it is not a problem in most cases if you see five or six or even more copies of svchost.exe running in your services because they host different groups of DLLs. However, there are several known spyware and trojans that pretend to be legal svchost.exe. They usually have the same name or one of the following names: svchost.exe, svchosts.exe (which often causes svchosts.exe page faults), Generic.exe, svcchost.exe and several others. Please note that legal svchost.exe should reside in Windows\System32 folder and should not appear in startup list.

Fixing Generic host Win32 Error:

Step1:

  1. Hop to ‘Run’ and open ‘Regedit’
  2. Navigate to:
    HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Services > Browser > Parameters
  3. Find the Key
    Name: IsDomainMaster
    and set
    Data: False
  4. Restart Your PC

Step2:

  1. Go to ‘Run’ and open ‘cmd’
  2. Type ‘netsh’ in command console then press enter
  3. Then type ‘winsock’ and press enter and then type reset
  4. Restart Your PC

Step3:

  1. Open ‘cmd’
  2. type regedit and press enter. This will lead you to the registry editor.
  3. Find the following key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\NetBT\Parameters
  4. In the right-hand window pane you will find an option called TransportBindName.
    Double click onTransportBindName and delete the existing default value and click Ok (This gives TransportBindName a blank value)
  5. Close Port 135: Navigate to the following registry key:
    HKEY_LOCAL_MACHINE\Software\Microsoft\Ole
  6. In the right hand window pane you will see an option called EnableDCOM. Double-click EnableDCOM and change the Y to an N and click Ok. Close the Registry Editor and restart your computer.

Hope this will solve your problem. 🙂

OpenSSL: Introduction

April 9, 2009 Leave a comment

OpenSSL is an open source implementation of the SSL and TLS protocols. The core library (written in the C programming language) implements the basic cryptographic functions and provides various utility functions. Wrappers allowing the use of the OpenSSL library in a variety of computer languages are available.
OpenSSL is based on the excellent SSLeay library developed by Eric A. Young and Tim J. Hudson. The OpenSSL toolkit is licensed under an Apache-style licence, which basically means that you are free to get and use it for commercial and non-commercial purposes subject to some simple license conditions.

Versions are available for most Unix-like operating systems (including Solaris, Linux, Mac OS X and the four open source BSD operating systems), OpenVMS and Microsoft Windows.

FIPS 140-2 Complience:

OpenSSL is one of the few open source programs to be validated under the FIPS 140-2 computer security standard by the National Institute of Standards and Technology‘s Cryptographic Module Validation Program.
[Note: FIPS stands for Federal Information Processing Standard]

Present Version:

openssl-1.0.0-beta1 [ Works under FIPS mode as weel as NON-FIPS Mode (Beta Version) ]

openssl-0.9.8k [Works under FIPS mode as well as NON-FIPS mode (Stable Version)]

openssl-fips-1.2 [ Works Under FIPS Mode ]

The other version of the setup files, documentations and other informations can be obtained from http://www.openssl.org/

Never Upgrade any Software!


Every year we see that various software companies release several software. Some of those software are so useful, that, we forget that, they will also need to update or upgrade.

For example, Nero. After opening the software in your machine you can see the version of it. It should show 6.x.x or 7.x.x or others. Right? Now, just Google the ‘Nero’. You will find, it is running 9.x.x version in the market.

Take another example, Adobe Acrobat Reader. We use this software for reading the PDF files. Now, open it. What version is it showing? 5? 6? 7? Or 8? Now, again Google the ‘Adobe Acrobat Reader’. It is running version 9 man!! What are you doing?

Go online and upgrade all these software. Open Nero’s website. Just a minute….what is it showing? The setup file of 9.0 version of Nero software is 370.5 MB???  Lol! Are they mad? If the setup is near about 400 MB, then what will be the size, if it installs??? Believe it or not, but it is 1.03 GB!!! Yes, from my personal experience, I am telling you. How horrible!!

In their site, they are saying that this time, Nero has become more user friendly and bla..bla..bla… But, in practical, if you see them, you will be more upset. What had they done? Is this our that Nero? It have become more user ‘foe’ly!  Not only Nero, but take any software.. Adobe Acrobat Reader, DivX, iTunes, Power DVD, Adobe Photoshop etc… you name it! These all are our everyday usable software. Not even software, now a days Operating Systems are also becoming monsters. Windows Vista? The os from Microsoft Corporation? Also have tested Windows 7. The same problem.

Now, lets take a small tour over the cons of these upgrading of softwares.

1. More and more Space: They want more AND more space every day. Previously, I have given an example of the Nero. Now, look at this table:

Name of the Software Previous / Most Used Version with Size Most recent Version with Size
Nero V6.x (<100 MB) V9.x (370.5 MB)
Adobe Acrobat reader V5.0 (<10 MB) V9.0 (>26 MB)
DivX V4.0 (0.7 MB) V6.8 (19.8 MB)
iTunes V4.1 (19.1 MB) V8.0 (65.6 MB)
Power DVD V1.5 (2.6 MB) V8.2 (76 MB)

These are the setup file sizes. Now, after installing, they occupy spaces like this: Nero 9.x = 1.03 GB, Adobe Acrobat Reader 9.0 = 230 MB, DivX 6.8 = 50 MB, iTunes 8.0 = 75 MB (without Quick Time, with Quick Time 100 MB). So, what will you do to your hard disk?

2. Unnecessary Functions: 99.9% of the users of Nero have a primary objective: burning a cd or dvd.  But, in the 9.0 version, you will find several tools that you will never use. For example, the Nero Home. I am sure that, you will never use it, if you have used the Windows Media Center once. More over, they give, a ‘Photoshop’-like software which is much harder in order to use the original Adobe Photoshop. You will find more applications like Nero Media Player. The ‘worst’ media player I (probably, you also!) have seen ever. Some times they provide some more ‘visually’ beautiful user interface (Eg. Nero 9), which looks great but works keen. They not only fail to do the job in time, more over pressures on the hardware of the computer which turns to our next point.

3. High Requirements: Windows Vista said that it will require at least 512 – 768 MB of RAM; however, 1GB is the best for the lowest requirement. Windows 7 has raised a step higher. It is demanding minimum 1GB of RAM. However, they said 2GB of RAM will be a good configuration in case of lowest RAM configuration. It was only the demand of RAM. Now, there remains more hardware: Processors, Hard Disk Space, Mother board, Optical Drive etc. Adobe’s latest Photoshop CS4 says of minimum requirement of 512 MB of RAM. But, in practice, I myself found, 1GB works good instead of 512 MB. But, if you guys could remember, the CS2 version had recommended requirement of 512 MB of RAM and, I myself had experienced, 320 MB was more than sufficient for it. My Intel 845GVSR motherboard with P4 2.4 GHz Processor ran the application very fast!

4. Customers are tester: When you buying a software, they will ensure in 1000 ways that, the software has been tested 10,000 times and rated “best value” by some ‘XXX’ magazine! You also look at that and think good of it and become the ‘bakra’. Coming back home, when you start installing it, the lines of problem starts. And until the software company provides a ‘patch’ or ‘update’, the problem persists. I think because of this since 2001 till today the Windows XP is providing ‘Service Pack 3’, ‘security updates’ and other ‘useful updates’. Not only XP, their last OS Vista had received a ‘Service Pack 1’ in 2008 after launching it in mid 2007. So, why will you buy new software, which has not been tested? Why don’t you use the previous versions of those software?? Here comes our last point.

5. Expensive: While Nero’s original burning software initially was used to given away with the CD-Writers at free of cost, the latest Nero 9 will cost you around US$200(probably). If you had purchased Adobe’s Photoshop CS2 or CS3 previously, then also, you have to buy it with near about US$1000(probably) with some US$100 discount. WHY? Why should I buy these software-monsters with 1000 bucks??

So, from the next time, before upgrading any software or OS, think twice. Don’t just follow the crowd of ‘latest versions’ and buy them. Apply your brain, is there really any need to buy a new software version? Can the Nero 9 burn ‘scratched’ discs?? You know the answer: No. Then why do you buy / upgrade it expending both your Income and the Internet Bandwidth??? Rather learn to use alternatives. Open Source Products. For example, In case of Vista os, use Fedora Core / Ubuntu / Cent OS…. These are FREE, OPEN SOURCE and FREELY UPGRADABLE Os which covers the solutions of all the problems stated above. Try to use ‘FoxIT Reader’ v2.3 (current) 2 free of cost with 3MB setup file size having all the features of Adobe Reader 8 and 9. Use VLC media player. This is also another open source media player software that plays nearly all types of files.  Yes, it is true, that, VLC is upgrading every month, but, that does neither require lots of internet bandwidth nor 100s or 1000s bucks as it is free and the latest version 0.9.8a (probably) has the less than 20 MB setup file; which will replace iTunes, DivX and Power DVD. So, apply your brain and think again before any software/os upgradation.
