Activate TPM Security
Hi everyone,
I'm having trouble activating TPM Security in the BIOS from Windows 7 x64.
I have two seperate executables, one which enables TPM in the BIOS and the other which is configured to activate TPM. The first one which enables TPM Security works fine however when the second file which is configured to activate TPM after rebooting the machine does not work.
Has anyone experienced this issue before and is there another way of activating TPM through Windows 7?
Thanks

Solution:
I simply resorted to using the following VBScript which enables bit locker and as a side will activate TPM if it is deactivated.. I could break it into two seperate tasks but have decided to keep it in the one.

'Version 1.2 - Updates
'1 - Removed infinate loop potential in the FindRemoveableDrive function. Three attempts are valid.
'2 - Added saving RK to the /USB option.
'3 - Will not look at local evet log if no policy key present.
'4 - Minor loging and text changes.
'5 - Fixed PIN input cancel button use.
