In a previous article, I discussed Microsoft Security Essentials (MSE). I like the ease of use, the integration with Windows Update, and the small footprint it has, especially on my netbook. Recently, Microsoft has released Microsoft Security Essentials Version 2 with some new features, including a new and improved protection engine, Windows Firewall integration, and a Network Inspection System.

A new look for MSE V2

As you can see, the user interface changed slightly, with a new color palette and mesh graphics. There are a few more options for the user to configure, but it is still one of the easiest anti-virus applications to setup. For more on the major improvements, here is a quote from the MSE web site:

Windows Firewall integration
Windows Firewall can help prevent attackers or malicious software from gaining access to your computer through the Internet or a network. Now when you install Security Essentials, the installation wizard verifies that Windows Firewall is turned on. If you have intentionally turned off Windows Firewall, you can avoid turning it on by clearing a check box. You can change your Windows Firewall settings at any time via the System and Security settings in Control Panel.

Network Inspection System
Attackers are increasingly carrying out network-based attacks against exposed vulnerabilities before software vendors can develop and distribute security updates. Studies of vulnerabilities show that it can take a month or longer from the time of an initial attack report before a suitable security update is developed, tested, and released. This gap in protection leaves many computers vulnerable to attacks and exploitation for a substantial period of time. Network Inspection System works with real-time protection to better protect you against network-based attacks by greatly reducing the timespan between vulnerability disclosures and update deployment from weeks to a few hours.

Award-winning protection engine
Under the hood of Security Essentials is its award-winning protection engine that is updated regularly. The engine is backed by a team of antimalware researchers from the Microsoft Malware Protection Center, providing responses to the latest malware threats 24 hours a day.

Now, in going through the program, I did find two options quite interesting...

Enable behavior monitoring and Enable Network Inspection System options in MSE V2

I did a little digging in the MSE V2 Help file and found this description of these features:

Enable behavior monitoring
This option monitors collections of behavior for suspicious patterns that might not be detected by traditional anti-virus detection methods.

Enable Network Inspection System
This option helps protect your computer against “zero day” exploits of known vulnerabilities, decreasing the window of time between the moment a vulnerability is discovered and an update is applied.

Here are a few of the other changes inside of MSE V2:

• Microsoft Security Essentials also supports Windows XP Mode in Windows 7
• The ability to limit CPU usage during scanning
• Automatic removal of quarantined files after a set amount of time
• You can now select between monitoring all files, incoming or outgoing

Microsoft Security Essentials Version 2 is available for Windows XP (SP 2 or SP 3)(x86), Windows Vista (x86, x64), and Windows 7 (x86, x64) and can be downloaded here.

Note:
The only issue I came across was that the update function inside Version 1 would not update the program to Version 2. I tried it on a couple of systems without success. I had to uninstall Version 1 first, then install Version 2.

Windows XP is currently the most popular operating system, with Windows 7 quickly catching up. As more and more people are moving from Windows XP to Windows 7, I thought I would spotlight a series of articles that I wrote a little while back. My move from Windows XP to Windows 7 was a 'side-by-side' migration, with two separate systems.

I, believe it or not, never used Windows Vista on any of my production systems. I ran Windows XP up until Windows 7 was released. I did run Windows 7 Release Candidates on a test system for several months before its release and was very happy with it. I even wrote a series of articles about it too. Here they all are.

Network shell (Netsh) is a tool an administrator can use to configure and monitor network devices on Windows based computers at a command prompt. A common use of Netsh is to reset the TCP/IP stack back to default settings.

But not only will Netsh reset the TCP/IP stack, but it can also completely reset your network adapter(s). It will also display the network diagnostics page in Windows XP.

Using Netsh in Windows XP

To use Netsh, you will need to open a Command Prompt. There are two ways to do this:

• Click the Start button, then All Programs, then Accessories, then click on Command Prompt

or

• Press + R. This will bring up the Run dialog box. Type CMD and press OK

Netsh commands in Windows XP

The following is a list of the Netsh commands you can use to reset your Windows XP network adapter:

Resets network interface informationnetsh int reset all

Resets TCP/IP and related components to a clean state.netsh int ip reset c:\resetlog.txt

Resets IPv6 configuration state.netsh int ipv6 reset

Displays the web page user interface.netsh diag gui

Resets Winsock Catalog to a clean state. All Winsock Layered Service Providers which were previously installed must be reinstalled. This command does not affect Winsock Name Space Provider entries.netsh winsock reset

When your computer runs low on Random Access Memory (RAM), and more is needed to complete your current task, Windows uses hard drive space to simulate system RAM. In Windows, this is known as Virtual Memory and often called the Pagefile. The default size of the virtual memory pagefile (appropriately named Pagefile.sys) created during installation should be 1.5 times the amount of RAM on your computer.

You can optimize virtual memory use by dividing the space between multiple drives and removing it from slower or heavily accessed drives. To best optimize your virtual memory space, divide it across as many physical hard drives as possible. When selecting drives, keep the following guidelines in mind:

• Try to avoid having a pagefile on the same drive as the system files.
• Avoid putting a pagefile on a fault-tolerant drive, such as a mirrored volume or a RAID-5 volume. Pagefiles do not need fault-tolerance, and some fault-tolerant systems are slow because they write data to multiple locations.
• Do not place multiple pagefiles on different partitions on the same physical disk drive.

#1 - Find out how much RAM your computer has

To open the System Properties, press + Pause. In the System section, under Memory (RAM), you can view the amount of RAM your computer has.

#2 - change the size of the virtual memory paging file

You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings might also prevent you from completing this procedure.

1. To open the System Properties, press + Pause


2. On the Advanced tab, under Performance, click Settings.


3. On the Advanced tab, under Virtual memory, click Change.


4. Under Drive [Volume Label], click the drive that contains the paging file you want to change.
5. Under Paging file size for selected drive, click Custom size, and type a new paging file size in megabytes in the Initial size (MB) and Maximum size (MB) box, and then click Set. If you decrease the size of either the initial or maximum page file settings, you must restart your computer to see the effects of those changes. Increases typically do not require a restart.

Notes:

• To have Windows choose the best paging file size, click System managed size.
• For best performance, do not set the initial size to less than the minimum recommended size under Total paging file size for all drives. Use the following formula for calculating the correct pagefile size. Minimum pagefile size is one and a half (1.5) x amount of memory. Maximum pagefile size is three (3) x minimum pagefile size. Say you have 4 Gb (4,096 Mb) of memory. 1.5 x 4,096 = 6,144 Mb would be the min. pagefile size and 3 x 6,144 = 18,432 Mb would be the max. pagefile size. Usually, you should leave the paging file at its recommended size, although you might increase its size if you routinely use programs that require a lot of memory.
• To delete a paging file, set both initial size and maximum size to zero, or click No paging file. Microsoft strongly recommends that you do not disable or delete the paging file.

In this article, I am going to share my five favorite tips for maintaining Microsoft Windows.

1. Checkdisk. This is the first thing I do when I get a system here in the shop. Errors do occur, and files do get damaged. Best to take care of this first thing. And yes, this can take a while, so I always recommend leaving your system on and let Checkdisk run overnight. That way, your computer is ready to go first thing in the morning.
   

   For more information on how to perform a Checkdisk, select your operating system below:

   Windows 10 Checkdisk

   Windows 8.1 Checkdisk

   Windows 7 / Windows Vista Checkdisk

   Windows XP Checkdisk

2. Delete Temporary files. This is the first place to look when you need to free up some hard disk space. These files served their purpose at one time, but the program that used them did not delete them for some unknown reason. When deleting temporary files, some may still be in use. I recommend deleting all files/folders that are over a week old. See below for the location of the temporary files folder on your version of Windows:
   
   Windows Vista / 7 / 8.1 / 10 - C:\Users\username\AppData\Local\Temp
   Windows XP - C:\Documents and Settings\username\Local Settings\Temp
   
   
3. Delete the Internet Explorer cache. This is the second place to look when you need to free up some hard disk space. I have seen systems with over 9 Gb of temporary files. Open Internet Explorer and go to Tools > Internet Options and change the following settings:
   
   
   
   
   
4. Pagefile optimization. This one often gets overlooked. There is a formula for calculating the correct pagefile size. Minimum pagefile size is one and a half (1.5) x amount of memory. Maximum pagefile size is three (3) x minimum pagefile size. Say you have 4 Gb (4,096 Mb) of memory. 1.5 x 4,096 = 6,144 Mb would be the min. pagefile size and 3 x 6,144 = 18,432 Mb would be the max. pagefile size.
   
   
   

   To change the pagefile size, you need to access the System Properties dialog box. Press + Pause (Windows Vista / 7 / 8.1 / 10 users select 'Advanced' system settings). Then select the 'Advanced' tab and under 'Performance' click on Settings. Then select the 'Advanced' tab and under 'Virtual memory' click on Change.

   For more information on how to change the pagefile size, select your operating system below:

   Windows 10 Pagefile Settings

   Windows 8.1 Pagefile Settings

   Windows 7 Pagefile Settings

   Windows Vista Pagefile Settings

   Windows XP Pagefile Settings

5. Disk Defragmenter. Probably the best single thing you can do to speed up your computer. Imagine a filing cabinet where all of the folders were out of order, and files were misplaced throughout the cabinet. How could you find anything? Same thing with your hard drive. Disk Defragmenter takes care of that for you. And you can run it as a scheduled task too.
