After removing an expired Norton Security from a Dell laptop, I found out that WindowsXP (H.E.) is not updating correctly. The first time I recognized the problem was when I have installed Windows Defender and tried to update it. After a few attempts to update it, the error "0x8024001D" came up. Then, the Windows Update, through IE, has been reading "Error number: 0x8024001D." Microsoft offered a solution to error "0x8024001," not "0x8024001D," which I have followed to the exact fix, but to no avail. Did anyone encounter this error? Or, has anyone managed to fix this error with success? (NOD32 has been installed to replace Norton, and it is working perfectly--after a few update difficulties).
