Fast Startup is a Windows feature designed to reduce the time it takes for the computer to boot up from being fully shut down. Using Fast Startup may negatively affect connectivity when using UA devices.
Symptoms
If Fast Startup is enabled, booting up from a full shutdown with your UAD-2 device connected to the computer and powered on may cause issues such as erroneous sleep mode error messages and disabled UAD plug-ins.
Disabling Fast Startup
To disable Fast Startup, press the Windows Key + R to bring up the Run dialog, type powercfg.cpl and hit Enter. The Power Options window should appear. Click Choose what the power buttons do from the column on the left.
Scroll down to Shutdown settings and uncheck the box for Turn on fast startup.
Note: If these options are greyed out then you may need to click Change settings that are currently unavailable.
Click the Save changes button to apply the changes.
