Hi I instaled windows 7 Enterprise SP1 VLK and i cant activate it i got error 0xC004F035 and a warning "It will be impossible to activate via KMS duw to OEM BIOS issues" I want to have it activated via KMS. Does the bios needs to be modified to use kms? if yes what and how? the laptop model its TOSHIBA C660-1LZ PSC1JE rw-EVERYTHING: sendspace.com/file/kohghv BIOS: support1.toshiba-tro.de/tedd-files2/0/bios-20120613151531.zip Ive searched the forum and didnt found a staight answer. I tried to add slic to bios, says succesful but when i verify its the same.
