Unable to log into Admin account even though no password was created

Good day all

I followed these instructions this morning to try to install software for my wifi adapter that windows 10 keeps on blocking.
Administrator account - Enable or Disable in Windows 10 - Windows 10 Forums[1]=User%20Accounts
I logged out of my local account, then logged into my Administrator account.
After I had logged into my Admin account I realised I still had to take my wife to work.
Without doing anything in my admin account, I shut my computer down.
When I got back home I tried to log back into my admin account but kept getting a message "incorrect password"

The problem is I have not set a password for my Admin account.
I have also tried to use my microsoft password but that doesn't work either.

Apart from turning turning my pc into a projectile, is there anyone that can off me assistance?

Try to disable the UAC and you should be able to download the app without being blocked, assuming that app is free of virus. Here is how to disable the UAC in Windows 10:

1. Open the Control Panel.
2. Go to User Accounts and Family Safety\User Accounts, click on the Change User Account Control settings link.
3. In the User Account Control settings dialog, move the slider to the bottom (Never Notify).
4. Restart your computer for your changes to take effect.

I disabled my antivirus, I also went to my firewall setting, told my firewall to let my app through & still get the same message,

I think I have found the problem though.
I see the digital signature has expired.
Windows has most probably revoked the software because of this.
D-Link has discontinued support the DWA 131 wireless usb adapter.

I upgraded from Windows 7 to Win 10 on Friday 25 September & everything was working fine until yesterday.
I see my cd/dvd drive is also not working now & had to download the software from their website even though I have a disk for it.

I still receive the same blocked message.

Hi Warren14! If you install an unsigned device driver on Windows 10/8 64-bit OS, it will cause a blue screen and your system will be unable to boot. But I don't know if this will also happen if you install a driver with an expired digital signature. Make sure you create a system restore point before proceeding to install your driver.

I have created a restore point.
I am running a windows 10/7 32 bit
Before I installed Windows 10 I checked my software & windows told me all my software was compatible with Windows 10.

I managed to delete my administrator account.
I typed cmd in the search bar.
Right clicked on it to run as administrator
enter

Code:

 net user administrator /active:no

to disable your administrator account.
then type

Code:

 net user administrator [/DELETE]

the just type "exit" to exit the command prompt
