Memory Support in Windows – Kernal v User Virtual Addressing

Last week I was on a workshop by Microsoft it was for troubleshooting performance issues on Servers.

One of the interesting thing which I came across in the workshop was about the memory management  and the way Windows handles the memory.

By default Windows allocate’s virtual address space to User mode and Kernal mode, Windows assumes that it has 4 gb of virtual address space and it splits it into two half.

ie. 2 GB virtual address space to Kernal and 2 GB virtual address space to User

We can tweak it and  allocate virtual address space to programs 1 GB to the kernel and to executive component.

This is how you can do it:

First un-hide the hidden files and folder make sure you unhidden the Operating system files too.

on the root directory ie C drive you will find boot.ini file take a backup of it on keep it safe.

Edit boot.ini and add \3GB at the end Continue reading “Memory Support in Windows – Kernal v User Virtual Addressing”

How to Virtualize Your Computer

Last Friday I have virtualized my Windows XP Laptop, before I start telling you guys, how its done I think its worth mentioning why I need to do it?

We normal Virtualize the physical server that are very old and start getting faults very often or they are too big for us to keep in our data centres.

I have dual booted my laptop with Windows 7 ’64 bit’ edition, Which works brilliant. However Win7 is as this is 64 bit version of Windows I had to work around quite a few applications which I use on daily basis to get them work on Win7.
However the most important software which I need to work from home is the vpn client provided by CISCO. The VPN client is yet to be rewritten for Win ’64 bit’ CPU. As a result I could not use Win7 to work from home, as I was unable to install VPN client to deil.

Now you can guess why I virtualized my Windows XP OS. Continue reading “How to Virtualize Your Computer”

Windows 7 Awesome again!

Although I had a bitter experience with beta version of win7, I cannot stress how much windows 7 has improved from beta to the on the shelf product.

When comparing with  the nightmares of resource hungry  Windows Vista  which can only be compared with windows ME edition,  I am now convinced that Win 7 is the next best product after Win XP. And I am sure most of you who have started using Windows 7 can’t imagine going back to XP again.

As you might be aware that Microsoft always has different versions of products available for his customers, I have highlighted few features which can help you decide which version is best for you.

I hope this will help you decide which one is best for you!
