Despite widespread belief that Windows XP will continue to thrive in the business environment, one analyst believes that actually XP is very close to the end of its life in enterprise.
Here are five other key factors that Forrester believes will loosen Windows XP's grip on the enterprise and make way for Windows 7.
Businesses are supporting old infrastructure
Forrester's Gray says that because of the recession, IT managers needed to lower costs by extending the life of existing desktops and laptops.
Many also held off on hardware upgrades because they wanted them to coincide with a Windows 7 deployment. For global companies that support thousands of apps, compatibility testing can take up to 18 months.
So if they've been testing in anticipation of Windows 7's release, full deployments will conclude by the end of 2010.
Windows XP support is waning
Since April of this year, Windows XP SP2 has been in the extended support stage, which means support is no longer free and only includes security updates and patches.
Next July, XP SP3 will enter extended support as well. All support for Windows XP SP2 and SP3 will end in April 2014.
Windows XP availability will get pinched
The ability to buy Windows XP machines will change now Windows 7 is available. With the release of Windows 7's first service pack, scheduled to be a year or so after its initial release, OEM licenses bundled with every PC will no longer have downgrade rights to XP.
This means that to deploy Windows XP on a new PC, companies will have to purchase volume license copies of Windows along with the new PCs or use existing, unused Windows volume licenses.
Business reasons encourage upgrade to Windows 7
Forrester has found that the enterprise features in Windows 7 will help companies improve networking and security and ultimately cut costs.
Some features that Forrester recommends IT departments prepare for include:
- DirectAccess, which lets remote workers connect to corporate networks without the use of a VPN
- BranchCache, which speeds up access to networks in remote offices that are away from corporate headquarters
- BitLocker To Go, an extension of the BitLocker hard-drive encryption feature introduced in Vista that will now protect removable devices like external hard drives and USB thumb drives
- AppLocker, which aims to protect users from running unauthorized software; and federated search, which promises to simplify access to data across local and remote networks.
Improved client virtualisation can accelerate deployment plans
Windows 7 ships with Windows Virtual PC and Windows XP Mode, which provide the ability to run apps not yet compatible with Windows 7 in an XP-compatible virtual machine.
Moreover, customers with software assurance agreements can use MDOP (Microsoft Desktop Optimisation Pack), a subscription-based suite of apps that includes virtualisation technologies allowing IT pros to deploy and manage virtual images, "thus removing the last barriers to deploy Windows 7," says Gray.
