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.

One of the questions I often get asked is, "What can I do to maintain my computer". So in this article, I am going to share my five favorite tips for maintaining your Windows-based computer.

Regularly check your drive(s) for errors

This is one of the first things I do when I get a system in the shop. An error on the disk can cause all sorts of issues, so occasionally running a quick standard disk check is recommended. It is always best to try fixing any errors before they become huge problems.

Manually defragment and optimize your drive(s)

Even though Windows runs Defrag as part of the routine maintenance (usually weekly), you can always occasionally run it, as it is 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 computer's drive. Disk Defragmenter takes care of that for you. And you can run it as a scheduled task too.

Select your operating system below for more information on how to use Disk Defragmenter.

Clean up your drive(s) regularly

Now, Windows does include programs to clean up the miscellaneous files that build up over time, but by default, it is not set up to run automatically. You can set up Windows to perform these routine tasks, which include deleting temporary files and emptying the Recycle Bin.

For more information on how to use Disk Cleanup and Storage Sense, select your operating system below.

Install Windows updates when they become available

Once a month, Microsoft releases security patches called Cumulative Updates. They fix known security issues and should be applied as soon as possible. Microsoft has been using the same schedule for
releasing them for decades now. The second Tuesday of every month is known in the IT world as 'Patch Tuesday', so mark your calendar. And if, for some reason, Windows Update does not work correctly, click on the link below.

Troubleshooting problems with Windows Update

Backup of your computer on a regular schedule

Nothing can beat a complete backup when it comes to getting a computer back running after a drive failure. Sure, a drive failure is an extreme example, but it could be an update that did not install correctly or a corrupt driver that is preventing your system from booting correctly. And the software is already built-in; all you need is an external drive for the backup and a USB flash drive for a repair drive.

In this article, I am going to spotlight Microsoft Security Essentials (MSE). This is not Microsoft's first venture into the ant-virus market, but it is probably the best. Having used some of the more well-know anti-virus software (Norton / Symantec, McAfee, etc.) for over a decade, I decided to give MSE a try.

All of the articles I had read on Microsoft Security Essentials were quite positive, so I installed it on my netbook running Windows 7 in June. Since then, I have taken the netbook on several on-site service calls and vacation. I am happy to report that the netbook remains virus-free. What I like is the small footprint the software has. It does not take five minutes to start up Windows, as can happen on systems with limited resources (such as netbooks).

MSE works quite well with Windows 7 built-in firewall. The interface is clean and easy to use, unlike some of the anti-virus software out there. It's easy enough for a novice user to navigate. It also integrates into Windows Update. Here's a quote from Microsoft's website:

Microsoft Security Essentials provides real-time protection for your home PC that guards against viruses, spyware, and other malicious software.

Microsoft Security Essentials is a free* download from Microsoft that is simple to install, easy to use, and always kept up to date so you can be assured your PC is protected by the latest technology. It’s easy to tell if your PC is secure — when you’re green, you’re good. It’s that simple.

Microsoft Security Essentials runs quietly and efficiently in the background so that you are free to use your Windows-based PC the way you want—without interruptions or long computer wait times.

I encourage you to take a look at Microsoft Security Essentials. It's simple and free.

When I changed over to the Android, one of the functions I wanted was to use its 3G data connection with my netbook. I found this great program from June Fabrics Technology called PdaNet. It allows you to tether your Android's 3G without having to do any hacking.

Once the installation is complete on both PC and Android, you will find connecting to be easy. Just connect the USB cable from the Android to the PC, start the PdaNet app on your Android and then use the tray icon in Windows to connect. Here's a quote from their website:

PDA.net has been one of the most popular software for Windows Mobile phones, Palm OS phones, and iPhones. It is now ported to the Android system! PdaNet provides you with FULL Internet access, so all your email, instant message programs will work without any setting changes. Supports both USB Tether and Bluetooth DUN.

PdaNet does NOT require root access or hacking your phone's firmware in order to work. It is just a regular Android application that works on all Android phones as-is. Tethering is fast, secure, and USB mode will also charge your phone at the same time. Your phone can either connect to 3G data, WiFi, or even through VPN, and PdaNet will share the connection with your computer.

If you are looking to connect to the internet on your computer through your smartphone, I recommend you go over to June Fabrics site and take a look at their line of PdaNet products. BTW: If you use Windows 7, you can create a WiFi hot spot with PdaNet and Virtual Router.

In my recent change to the Google Android from a Palm, I required two main functions. The second one was to be able to synchronize my Android to Microsoft Outlook. I have been using Outlook as a PIM (Personal Information Manager) for years now, as it's the 'de facto' standard in the corporate world. I was pleasantly surprised to find DejaOffice by CompanionLink.

Being on the Palm platform for years, I became kind of pampered when synchronizing data with Outlook. This really was one of Palm Pilot's strong points. So when I found DejaOffice, it was just the perfect replacement for the conduits from Palm. With the ability to sync Contacts, Tasks, Calendar, and Notes, this is a 'must-have' if you use Outlook. Here's a quote from their site:

Data from the PC sync to DejaOffice, a mobile office application suite for Android. DejaOffice features robust contacts, calendar, tasks, and notes apps that provide enhanced functionality over the native Android applications. Contacts and calendar automatically sync with the native Android databases to allow for full functionality with other apps.

I highly recommend you give this program a try. It's available from the Android page at CompanionLink.
