Fixing the Windows 7 is not genuine message

While I’ve run various builds of Linux for many years, I still have to routinely test my work in Windows. While I often attempt to keep my laptops able to dual-boot into Windows, that only (realistically) supports only a single version of Windows. For older versions, I generally rely upon VirtualBox and can then have different configurations available when needed, while keeping my Linux apps open too!

Occasionally, I’ve had a virtual machine running a licensed copy of Windows 7 start warning that it is not activated. This can prove to be annoying for several reasons, as such I did some research and found that others have encountered the same problem and shared the below solutions.

First method:

  1. Open a command prompt in Administrator mode.
  2. Execute “slmgr -rearm”
  3. NOTE: some sites tell you to locate and remove “slui.exe” – DO NOT DO THIS!
  4. Restart Windows
  5. Problem should be resolved

Alternative – reactive with your product key:

  1. Open a command prompt in Administrator mode.
  2. Execute “slmgr –upk
  3. Execute “slmgr –ipk (your product key)
  4. Restart Windows
  5. Problem should be resolved

Name based virtual hosting with Apache2 on Ubuntu

I often find it necessary to setup a temporary server for testing web applications. The easiest way to support this is often to create an integration (beta) test server that can be configured to support multiple hosts.

Initial Installation:

sudo apt-get install apache2
sudo a2enmod proxy
sudo a2enmod proxy_http
sudo a2enmod rewrite
sudo chmod 755 /var/www

To add a new site:

cd /etc/apache2/sites-available
sudo cp 000-default.conf yourdomain.com.conf
sudo vi yourdomain.com.conf
(change values as appropriate)
sudo chown -R YOURUSER:YOURGROUP yourdomain.com.conf
sudo mkdir -p /var/www/yourdomain.com
sudo chmod 755 /var/www
sudo vi /var/www/yourdomain.com/index.html
(add some fluff)
sudo chown -R YOURUSER:YOURGROUP /var/www/yourdomain.com
sudo a2ensite yourdomain.com
sudo service apache2 reload
sudo service apache2 restart

NOTE: replace YOURUSER and YOURGROUP with appropriate values for your server.

Open Source Desktop Virtualization

Through the years, I’ve had to develop, maintain and support software on a variety of systems. Unfortunately, it’s often impossible to maintain specific software versions or configurations installed on physical machines. In the realm of web development, this becomes increasingly complex because of the rapid release of multiple browser versions.

To aid in testing, I’ve found that it’s often best to run these configurations in Virtual Machines, I’ve used VirtualPC and VMWare in the past, but have recently become a fan of Sun‘s OpenSource release of VirtualBox as it runs on a wide variety of host systems and supports most x86 based operating systems as clients.

Microsoft Virtual PC

I happened to spend most of this week in an IBM class using VMWare for the training environment (Windows XP Pro hosted on a Windows 2000 machine). This got me wondering about the free systems offered by many providers.

Here’s a few quick thoughts on Microsoft‘s offering, which admittedly seems pretty good.

Their product overview shows that you can run most (all?) previous Microsoft Operating System’s (MS-DOS, Windows 95/98/Me/2000/XP/Vista… etc. ), even IBM’s OS/2 all on a single host machine with enough resources. Minimum usage per VM appears to be about 64MB RAM and 500MB disk space for the older OS’s, newer versions obviously requiring significantly more resources.

Since I’ve got most of these old OS installation disks in storage, I’ll give this a try and see how well it works. This may make for some interesting testing lab scenarios.
