I feel like this is a common issue and I've missed something, but I have been unable to fix it! My wife's laptop (Lenovo G550) came with Windows 7 Home Premium 64 Bit. It got to the point a few weeks back when I decided it was probably better to reinstall from scratch. So I did a clean install on a new hard drive of Windows 7 Home Premium 64 SP1. Unfortunately the sticker with the license code had worn down to the point of not being readable. I opted to use the OpaTool to install a SLIC key. At this point her computer says it is permanently activated and everything is working great except for one thing: it won't install Windows Updates. It says "Windows Update cannot currently check for updates, because the service is not running. You may need to restart your computer." I have tried several possible solutions I've found including stopping and restarting the update service; manually removing the SoftwareDistribution directory; running windowsupdatediagnostic.diagcab, and Microsoft Fixit 50202. I am not sure what else to try. I'm suspicious that it might be an activation issue, but I have not found any references to problems like this when Windows is actually reporting that it's activated. I'd appreciate any advice anyone has.
