I had to do some fixed to my password tool to cope with forums that used a very short field
some choked on even a short 128-bit password
so now running servers ad-nauseum under Hyper-V, how strong can I protect the administrator account?

Upper range is 128 bit ( 127 practical scenario)

and if you are testing on Local accounts it is 28 character long.

I use remote desktop to manage my virtual machines and as such they are equivalent
I am aware that Windows 8 can use at least 16 symbols which is its limit

Per the link Sainath provided, the limit is 128 bytes (characters) for passwords in AD. When I tested in the past I was able to assign a 127 character password, but the GUI did not allow 128. 127 bytes is 1016 bits.

256-bit is about 80 characters based on the entropy found in printable ASCII
using a TOP SECRET rated password helps make it safer (256-bit or more)
