Microsoft blacklists leaked Windows 7 OEM key
Yesterday we were alerted to reports of a leak of a special product key issued to an OEM partner of ours. The key is for use with Windows 7 Ultimate RTM product that is meant to be pre-installed by the OEM on new PCs to be shipped later this year. As such, the use of this key requires having a PC from the manufacturer it was issued to. We've worked with that manufacturer so that customers who purchase genuine copies of Windows 7 from this manufacturer will experience no issues validating their copy of Windows 7
. At the same time we will seek to alert customers who are using the leaked key that they are running a non-genuine copy of Windows. It's important to note that no PCs will be sold that will use this key.
Windows 7 already includesan improved ability to detect hacks, also known as activation exploits, and alert customers who are using a pirated copy. There is a hack that is said to enable, when paired with the leaked key, a system to install and use a copy of Windows 7 Ultimate. Both the hack and the key are indications that a copy of Windows may not be genuine. The Windows Activation Technologies included in Windows 7 are designed to handle situations such as this one, and customers using these tools and methods should expect Windows to detect them.

Still im fine, but one day who knows ?
