After upgrading to windows 7 I have certain internal and external websites that will not allow the numbers on side of keyboard to work. I found some .net 4 security updates that were blocking those number keys. After removing updates the problem went away for a short time on one computer. The other computer I had to remove .net 4 completely before I could use the numbers on the side. Both computers after seeing them work stopped working again without the security updates being reaplied.
The .net security updates that I removed from Microsoft said this, "This update resolves vulnerabilities that could allow elevation of privilege if a user goes to a specially crafted website or a website that contains specially crafted web content."
If I remote into the computer using vnc everything works fine. I just cannot use the side numbers keys when sitting at the local pc.
Any ideas that may help with this would be great.
