Guid

[viveksrivastava]

How to know MachineGuid?

[qxoz]

For windows OS you can read from registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\MachineGuid
but i think that GUID not unique as expected

[viveksrivastava]

not accessable

[tzander]

Maybe you want to generate one and write it to your config file to use it from then on out?

[viveksrivastava]

No, I want to read HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Cryptography\MachineGuid

[tzander]

Then why ask on a Qt forum? :)

You can use the microsoft APIs for that, I imagine.

Nope, QSettings can read from there just fine.

Thanks, I have already try QSettings and I easily read all other key in registry but in case of MachineGuid its return null.
