Intel faces challenges in migrating from Windows XP to Windows 7, including application incompatibility and system readiness, the company said.
Intel worked with Microsoft to develop Windows 7 into a stable operating system, but there is still a lot of heavy lifting involved before migrating PCs to the new OS inside Intel's environment, wrote Intel staff engineer Roy Ubry in a blog entry. Challenges include issues related to backward application compatibility, web browser support, 64-bit computing and privacy controls.
"It means that a significant amount of work needs to be invested to prepare for Windows 7 application readiness," Ubry wrote. Intel last year announced it would migrate from the nine year old Windows XP OS to Windows 7 OS, skipping Vista, which was released in 2007. Now the company is starting its transition to Windows 7.
One of the biggest issues involves migrating applications that can run natively on Windows XP to Windows 7. The move from Windows XP systems to 64-bit computing in Windows 7 presents an application compatibility challenge while migrating PCs, Ubry wrote. Windows 7 no longer supports 16-bit programs, and Intel still has many legacy applications that will require the company to support older operating systems.
"Initially, you would think this would not be a big concern; 32 bit computing has been around for many years, and most applications have been ported to 32 bit," Ubry wrote. But for companies that want to migrate to Windows 7, the 16-bit programs will need to be changed to either 32-bit or 64-bit programs.
Another challenge involves the way Windows 7 deals with 32-bit programs. Windows 7 saves 32-bit programs on a different path, typically in a directory called Program Files (x86), from 64-bit programs, which are saved in the Program Files directory. That raises a set of problems while searching for specific applications, Ubry wrote. "Applications that are hard coded to look for 'Program Files' at runtime will fail when the application is installed in 'Program Files (x86)'," Ubry wrote.
As much of a challenge as it is, the move to 64-bit computing is necessary and timely, Ubry wrote. It prepares Intel for future computing needs and takes advantage of the higher memory capability of systems available on the market today.
Intel has also delayed deployment of Internet Explorer 7 and IE 8, as they are not compatible with specific add-ons and applications written for Internet Explorer 6. Many applications like some Office add-ons and versions of Java are written to run with IE 6, and "mitigation of these issues must be addressed," Ubry wrote.
Intel is also trying to tackle some improved privacy features built into Windows 7 that could create issues when trying to run programs. Microsoft has improved security in Windows 7 with an improved UAC (User Access Control) feature, which seeks permission from a user before providing access to programs. But some programs may not seek user permission and could just fail without warning, Ubry wrote. Microsoft has provided an answer that could remedy the problem with the option to run the program as an administrator.
Intel is also taking a number of steps to migrate smoothly to Windows 7. The company has set up application inventories and test environments and has established a "safety net" to run native XP applications. The safety net includes running XP applications in virtualised environments or using XP Mode, a feature in Windows 7 that allows users to run native XP programs.
