How to Maintain the Speed of a Freshly Installed Windows OS

1. Normally, people ask 'Antivirus soft wares are supposed to be in-built for an OS if they promise security, right? So why is it that I can't find it in my OS?'
2. Well the answer is, improved security is one of the promises offered by any OS from its previous versions. As in Windows, there are two things which can be obviously seen. One is the Windows Firewall, the other is Windows Defender. Both took a giant leap from XP to Vista. But there is a silent warrior performing security measures in Windows apart from the above two. Anyway, I am talking about the Data Execution Prevention(DEP for short) module in Windows systems. By default, it is started up both in XP and Vista when the system boots up, their capabilities are widespread, but in a nutshell what they do, is they monitor every file in your OS, when they are MODIFIED, even in the most slightest way. Although DEP is a really great thing, it does the most to slow down your system. Initially in a freshly installed OS, you won't even notice DEP's influence, but as you install and add more files for your OS to monitor, that's when all hell breaks loose. Consider copying a file about the size of 500MB or more, when the OS is fresh, this should be nearly a piece of cake, but when your hard drive is filled up, you can take two cups of coffee before the process gets done, Phew! that's what happened when I had DEP enabled in Vista sometime ago. You can't really blame DEP, it's doing good to you at the cost of speed, so I think I gave you enough info on this, let's get to the point of disabling them, oh and don't PANIC!! It's no big deal. Here is what you need to do.

For XP Users

   Make sure you're a user with administrative rights.
2. How to Maintain the Speed of a Freshly Installed Windows OS Picture 2
   Go on to Control Panel -> System -> Advanced Tab, and under Startup and Recovery click Settings.

   A new window pops up, in which you must click the 'Edit' button.
4. How to Maintain the Speed of a Freshly Installed Windows OS Picture 4
   You should see a text file opening up. This is your system's bootloader settings, don't touch anything in their which you don't know about.
5. How to Maintain the Speed of a Freshly Installed Windows OS Picture 5
   In the last line you should see something like this '/NoExecute=OptIn'. Bingo!! You found the roots of DEP, all you have to do is change the value 'OptIn' to ' AlwaysOff ' (without quotes, 'A' and 'O' should be in capitals).
6. How to Maintain the Speed of a Freshly Installed Windows OS Picture 6
   Now save the file and close it, for those who want to know where the actual DEP is, under Advanced Tab click on Settings which is under Performance, you should find DEP in the popped up window.

   Now restart the system, and feel the first speed boost to your XP system.

For Vista Users

1. Since Vista doesn't allow you to directly edit the bootloader settings, here is how you do it in Vista.
2. How to Maintain the Speed of a Freshly Installed Windows OS Picture 8
   Be sure to be a user with administrative rights.
3. How to Maintain the Speed of a Freshly Installed Windows OS Picture 9
   Click Start -> Run and then type in 'command.com' without quotes and then you should have the command prompt.

   ' bcdedit.exe /set {currentuser} nx AlwaysOff ' (without quotes)
6. How to Maintain the Speed of a Freshly Installed Windows OS Picture 12
   If you did it correctly, it will say 'The Command Completed Successfully'. Now restart the system.
7. How to Maintain the Speed of a Freshly Installed Windows OS Picture 13
   For Vista users who do not own Vista Service Pack 1, I would recommend you order it, and get it installed in your system as soon as you can. Personally I felt a great speed boost in Vista SP1 compared to the normal Vista installation. I would recommend you to disable DEP after you install Vista SP1 if you really have the need for speed .

   If DEP is disabled, doesn't that make my system more vulnerable to attacks though it improves my speed?'

   1. 3rd party Antivirus softwares will rescue you from that trouble, That's what they were built for! I wrote this post, because, DEP is somewhat old school to hackers and viruses. They learned to get past them, so DEP is just slowing things down for you, if you think keeping them enabled will save you from malicious codes. As for antivirus softies unlike DEP, they are not embedded to your OS, you can always turn them off with a simple click later, so they don't pick on your operating system's speed while your working.

1. Virtual Memory is very important if your running applications which require large memory space to run. It acts as a standby to load memory-hungry applications until actual physical memory becomes available. It works on the concept of swapping. You're going to use a predefined hard-disk space which is going to emulate the actual physical memory. So let's see how to access your Virtual Memory settings from Windows and modify it to favor speed.
2. How to Maintain the Speed of a Freshly Installed Windows OS Picture 32

7. How to Maintain the Speed of a Freshly Installed Windows OS Picture 37
   Select any of the partitions in which you have abundant space. Now click on custom size, and set the initial and maximum size to be the same value. This is very important because, when you set both the sizes to the same value, it helps to assure Windows that, at any given time, this specified space will be readily available for it to use, if done otherwise, causes some delay for Windows to move from initial value to the mark in the maximum value.
8. How to Maintain the Speed of a Freshly Installed Windows OS Picture 38
   Click OK, and restart the system.
9. How to Maintain the Speed of a Freshly Installed Windows OS Picture 39
   If you're having some trouble in picking a virtual memory size for a partition, consider your physical memory space to help.

   1. For example, if you have 512MB physical memory in your computer, it's wiser to set the initial and maximum value to the double of 512 in other words set it to 1024MB. Whatever your memory size be, just double it and set it for the virtual memory.

If you're not a big fan of Windows Searching capabilities like in the start menu or when you open a window, you might want to disable the Indexing capabilities of Windows as well.
