Microsoft said Friday that its inquiry confirms that a tool aimed to make it easier to load Windows 7 on a Netbook does in fact contain open-source code.
"After looking at the code in question, we are now able to confirm this was indeed the case, although it was not intentional on our part," Microsoft's Peter Galli said in a blog posting. "While we had contracted with a third party to create the tool, we share responsibility as we did not catch it as part of our code review process. We have furthermore conducted a review of other code provided through the Microsoft Store and this was the only incident of this sort we could find.
As a result, Microsoft said it will make available next week the source code for the tool as well as the binaries under the terms of the General Public License (GPL v2). Microsoft will also make the tool again available to customers at the Microsoft store.
Microsoft had pulled the software utility down earlier this week after blogger Rafael Rivera noted in a posting that the tool appeared to use code from the open source ImageMaster project. (Of note, that project is now no longer available on CodePlex, where it had been posted).
Though somewhat arcane, the Windows USB/DVD Tool was Microsoft's answer to a tough problem--upgrading the operating system on Netbooks and other PCs without an optical drive.
Microsoft had been exploring for months different ways to handle the issue, eventually settling on this software program, released last month, which lets users take a downloadable copy of the operating system and create a bootable drive.
Releasing software under an open-source license is not entirely new to Microsoft, although Microsoft typically doesn't do so under the GPL, which it sees as one of the more restrictive of the open-source licenses.
The software maker did release a few Linux drivers under GPLv2, although it may have had its hand forced there as well. Some have suggested the drivers contained GPL code, meaning that they necessarily would have had to be released back under the same GPL license.

Microsoft has halted distribution of a tool aimed at making it easier to put Windows 7 on Netbooks amid allegations that the utility makes improper use of open-source code.
The software maker said on Tuesday that it has pulled down the Windows USB/DVD Tool while it investigates the issue, which was raised last week by Windows blogger Rafael Rivera on his Within Windows blog.

In his blog post, Rivera said Microsoft appears to use code from a tool called ImageMaster that is licensed under the GPLv2 open-source license. The General Public License, like other open-source licenses, allows code to be freely used by others, but has its own set of terms and conditions, such as sharing any modifications made to the code.
Microsoft confirmed it has launched a review of the matter and taken the utility off its online Microsoft Store until that inquiry has been completed.
"Microsoft is looking into this issue and is taking down the (Windows 7 updating) tool from the Microsoft Store site until its review is complete," the company said in a statement. "We apologize to our customers for any inconvenience."
Though somewhat arcane, the utility is important because it solves a technical challenge in upgrading the operating system on Netbooks and other PCs without an optical drive.
Microsoft had been exploring for months different ways of trying to help users of Windows XP-based Netbooks move to Windows 7. The tool, which was released last month alongside Windows 7, allows users to take a downloadable copy of the operating system and create a bootable drive.
The issue is also a thorn in Microsoft's efforts to show that it can play nice with the open-source community. As ZDNet blogger Mary Jo Foley notes, this isn't the first time Microsoft has been accused of misusing GPL code.
The latest dust-up comes as Microsoft is celebrating the third anniversary of its deal with Novell, one of Microsoft's biggest--and most controversial--efforts to blend its world with the open-source world.
Under that deal, Microsoft agreed not to sue Novell customers for their use of its Linux distributions.
Microsoft has also released a number of products under various open-source licenses itself, though typically not under the GPL, which it sees as one of the more restrictive licenses. Redmond has been particularly critical of terms in version 3 of the GPL.
The software maker did release a few Linux drivers under GPLv2, although it appears its hand may have been forced there. Some have suggested the drivers contained GPL code, meaning that they would have necessarily needed to be released back under the GPL.
Microsoft has taken a number of different approaches to open-source software, particularly Linux. The software maker has at times accepted the notion of a heterogeneous world where Linux and Windows co-exist, pledging to do better to make sure IT administrators can manage mixed environments.
At other times, Microsoft executives have lashed out, painting open-source software as violating hundreds of Microsoft patents. In its lawsuit against TomTom earlier this year, Microsoft for the first time made those accusations in court, alleging that TomTom's implementation of Linux in its GPS systems infringed on Microsoft patents. The two companies quickly settled the matter, although terms were not disclosed.
Microsoft's move to offer several Linux drivers owes a lot to a key programmer at Novell.
Linux veteran--and Novell fellow--Greg Kroah-Hartman suggested to Microsoft about four months ago that the company release the three drivers to be part of Linux under the GNU General Public License (GPL) terms that govern Linux code. Kroah-Hartman, who helps oversee the inclusion of drivers into Linux, said he worked within his company to find the right contacts at Microsoft.
"They reacted well," Kroah-Hartman said in a telephone interview on Tuesday. "They were open to it. It just took a while to hash out all the details."
Microsoft's Sam Ramji credited Kroah-Hartman for helping guide Microsoft through the process. "He provided valuable guidance and feedback to the Open Source Technology Center, which enabled the team to contribute the code in a way that was acceptable with the Linux kernel community processes," Ramji said in an e-mail interview.
The move illustrates the combination of social, legal, and technical factors that must be addressed before Microsoft's code could arrive. Anyone may contribute software to the Linux kernel, but actually getting it accepted can be a complicated matter, even for a company that hasn't bad-mouthed the GPL. This time, at least, Microsoft's pragmatism carried the day.
Microsoft had been working on the code contribution for some months, Ramji said; it happened to be ready in time to announce this week to coincide with the OSCON 2009 open-source conference.
As I noted yesterday, Microsoft made the move largely to help strengthen Windows Server as a host environment for Linux.
"Microsoft decided to release the drivers to support broader adoption and facilitate better performance of Linux running as a guest operating system where Windows Server 2008 is the host," Ramji said.
Kroah-Hartman said Microsoft met all the requirements for inclusion of the code in the Linux kernel and said it will probably show up in version 2.6.32 of the kernel, which will be released about four or five months from now.
Microsoft said it made sense to release the code under version 2 of the GPL, even though Microsoft has been critical of the GPL and used other open-source licenses for most of the code it has made freely available in the past.
"Because GPLv2 is the license of the Linux kernel, we are releasing the device driver code under the GPLv2 license to facilitate interoperability," Ramji said. "Our use of the GPLv2 license, as requested by the Linux community, means we will not charge a royalty for or assert any patents covering the driver code we are contributing."
Kroah-Hartman, who heads the Linux Driver Project, has been arguing for some time that all Linux drivers should be released under open-source licenses and said that Microsoft's move represents a change in its attitude toward the GPL and highlights that the GPL is a valid license for a project to be released under.
"It's just a validation of what all of us have been publicly saying for many years," Kroah-Hartman said.
He noted that Microsoft is now a full fledged Linux developer and will be responsible for maintaining its piece of Linux. He noted that the community has already submitted a couple of patches aimed at improving Microsoft's code.
Microsoft didn't close the door to contributing more to Linux.
"We expect to maintain the Hyper-V Linux device drivers as part of our product development and support process for Hyper-V, which we expect will involve ongoing contributions," Ramji said. "Part of the OSTC's charter is to continually evaluate open source, market conditions, customer requests and scenarios, and as such we will evaluate possibilities to work with additional open source projects in the future, including the Linux Kernel."
I asked Ramji whether Microsoft sees any dissonance in contributing to Linux at the same time it has claimed that Linux violates its intellectual property. His answer:
"Microsoft is pragmatically focused on helping customers and partners be successful in a heterogeneous technology world," Ramji responded. "We both compete and partner with traditional commercial vendors, and will continue to do so with open source-based businesses, with a focus on providing value for shared customers."
Kroah-Hartman said he doesn't spend a lot of time on the legal questions.
"Hey, companies are big," he said, noting that sometimes one part of a company has a different stance than another. "It has nothing to do with me."
Microsoft and TomTom have reached a settlement in their respective patent suits, the companies said Monday.
As part of the deal, as TomTom will pay Microsoft for patent protection related to mapping patents and file-management patents that Microsoft claimed were infringed by TomTom's use of the Linux kernel. Microsoft will also get access to the TomTom patents that were cited in TomTom's countersuit against Microsoft, although Microsoft won't make any payment to TomTom.
In a statement, the two companies said that the settlement provides TomTom patent coverage "in a manner that is fully compliant with TomTom's obligations under the General Public License Version 2." As part of the agreement, TomTom will "remove from its products the functionality related to two file management systems patents" over the next two years. The agreement protects TomTom's customers under the patents during that time, the companies said.
The settlement has a five-year term. Specific financial terms were not disclosed. With respect to Microsoft's mapping patents and TomTom's patents, the two companies have agreed to take no further legal action for the duration of the term. In the case of the three file management patents, Microsoft is providing an agreement not to sue customers for their use of TomTom's products.
"We are pleased TomTom has chosen to resolve the litigation amicably by entering into a patent agreement," Microsoft deputy general counsel Horacio Gutierrez said in a statement.
Microsoft filed its legal actions against TomTom last month. Attention was focused on the Linux claim as it marked the first time that Microsoft had filed court papers with its long-held assertion that Linux infringes on its intellectual property.
"This agreement puts an end to the litigation between our two companies," said Peter Spours, Director of IP Strategy and Transactions at TomTom, in a statement. "It is drafted in a way that ensures TomTom's full compliance with its obligations under the GPLv2, and thus reaffirms our commitment to the open source community."
Although the pact may settles things for TomTom, it adds further questions marks for where Microsoft is headed with its broader claims against Linux. The software maker has refused to go into detail as to what actions it might take against other companies that use Linux commercially.
However, the company has aggressively sought patent deals with companies that use Linux commercially. In addition to its deals with Linux vendors such as Novell, TurboLinux, and Xandros, Microsoft has also signed pacts with consumer electronics firms that use Linux, such LG, Samsung, and Fuji Xerox.
In recent interviews, Gutierrez has said that, although each case is different, Microsoft has an obligation to its shareholders as well as to the companies that have taken patent licenses to ensure that Microsoft is being fairly compensated for its intellectual property, including in cases involving Linux.
Until the TomTom case, we had only seen examples where Microsoft was able to convince companies to take a license. The TomTom case shows, though, that we may see Microsoft begin to take further action when negotiations don't lead to a deal.
