It's not yet blacklisted. i enabled windows updates. nothing happened till now.. so it's just some rumour. some system is showing black listed , is because of wrong usage of loader or win7 Activation toolkit, even i experieneced that. but this lenovo key is still working fine for me in mod bios. even i daily trying installations in virtual pc's and getting activated successfully.. so I Agree that still the key is not blacklisted.
ya just ran mu & wu. Both worked with no issue. says no more updates available. I used the loader. Have it on 2 lappys and 1 desktop. all genuine and still activated.It confusing why your having that. Besides like everyone says it will be a wrap as of late October early November. by then too late for ms. keys will surface.
