Following the installation of AU, I have been playing with Fast Restart and Hibernate on my 4 GB 64-bit PC.

powercfg /h /type full
works, but the alternative option
powercfg /h /type reduced
gives "The parameter is incorrect."

I have tried
powercfg /h /size 1
(in spite of the minimum percentage being shown as 40), then
powercfg /h /type reduced
which now works!

Is this the experience of anyone else?
