Code Integrity (CI) protects Windows Vista by verifying that system binaries haven’t been tampered with by malicious code and by ensuring that there are no unsigned drivers running in kernel mode on the system. CI starts as Windows starts up. The boot loader checks the integrity of the kernel, the Hardware Abstraction Layer (HAL), and the boot-start drivers. After these binaries have been verified, the system starts and the memory manager calls CI to verify any binaries that are loaded into the kernel’s memory space. The binaries are verified by looking up their signatures in the system catalogs. Aside from the kernel memory space, CI verifies binaries loaded into a protected process and system installed dynamic libraries that implement core cryptographic functions.

I am surprised it boots t safe mode.

Do these steps.

1. With system off. Unplug any USB devices including memory/pen drives.

2. Boot normally. If still problem reboot to Safe mode.

3. Uninstall if allowed the last software you installed. (if this software is Windows installer based you will not be able to uninstall it in Safe mode).

4. Use Msconfig to disable all possible startup programs.

5. Try a normal boot.

If no joy then try a system restore.

Then report back!

it works!

i´ve disabled anything form system start with msconfig in safe mode.
then restart in normal mode - works.

after that i rechanged the settings in msconfig an did a restart. now it works in normal mode!

but what was the problem??
the latest software i´ve installed was windows update.
