This is a heads up for people upgrading to Windows 8
I recently upgraded to the RTM of Windows 8. I went through quite a bit of hassle not related to BitDefender but like others doing a simple upgrade
from Windows 7 Ultimate to 8 Pro caused me to uninstall and reinstall BitDefender. That wasn't a big issue.
So then comes the Windows Activation. I had Microsoft on the phone for about an hour with their head scratching, so at one point they suggest
disabling my AV. So, I turned off active virus scanning etc. rebooted and viola Windows activation worked with BD Antivirus disabled. I've since re-enabled it and I'm still activated.
So if you see strange errors trying to Activate Windows 8, here's what we did.
From the Main Panel, Click on the cog wheel on Anti-virus, disable both On-Access and Active Virus control. Make sure the on-Access is permanent for now.
Reboot, activate your product and turn these settings back on.
