Hello Tans,
The core of your issue centers on the line in your Diagnostic Report that reads:
File Scan Data-->
File Mismatch: C:\Windows\system32\dnsapi.dll[6.0.6001.18000]
This means the file has been Tampered, Modified or has become Corrupt. Vista sees this as an attack to bypass its Licensing security.
To resolve the issue, you need to either repair or replace the file with a known-good one (of the proper file version)
First try repairing Windows using System Restore:
1) Reboot Vista into Safe Mode
2) Go to Control Panel
3) On the left hand side of the Control Panel window, Click on "Classic View"
4) Double-click "Backup and Restore Center"
5) On the left hand side of the window, click "Repair Windows using system restore"
6) Select "Choose Different Restore Point", Put a check in the box that says "Show restore points older than 5 days", select the restore point that corresponds to the date Before you first noticed the issue.
7) Click the "Next" button.
8) Reboot back into Normal mode
9) Vista should no longer be in Reduced Functionality mode
If that doesn't work, we'll try doing a System Scan. The scan will look for bad Vista files and will attempt to repair them, if possible.
1) Login to Vista in Normal Mode (not safe mode)
2) Launch an Internet Browser
3) Type: %windir%\system32\ in the browser's address field
4) Scroll down till you find the file cmd.exe
5) Right-click the file and select 'Run as Administrator'
6) In the CMD window, type: sfc /scannow
7) Reboot twice and see if that resolves the issue.
If neither of these sets of steps resolves the issue, my only other suggestions would be either to contact Vista support at http://support.microsoft.com or reinstall Vista.
