Microsoft would prefer if everyone only used the Balanced profile along with the power slider it provides in the system tray. I will send you an updated version of ThrottleStop that handles the Windows power plans better but it might not be able to solve the problem you are having. How did you create the additional power plans that you were using? Did you import them from a file or did you duplicate one of the profiles that you already had? If you duplicated one of the profiles that Windows likes to hide then that profile you created might now be hidden. Switch back to your Balanced profile (Zrownowazony) and the power slider should reappear. If you switch to the default Windows High Performance profile or to the default Windows Power Saver profile, the slider will disappear. The slider in the system tray to change power plan settings is only available when you are using the Windows Balanced profile. Windows 10 has a feature where it likes to hide the power plans that are on your computer. What version of Windows 10 are you using?
These power settings in registry are called 'System Unattended Sleep Timeout', and are not available in GUI on Microsoft Windows Vista, 7, 8, 10, or maybe later versions. Before you do, make sure you back up the registry first, you can restore it if anything goes wrong. ThrottleStop did not delete any of your Windows power plans. This fix involves manual changes of registry settings for power plans.
