Cannot switch from Selective startup to Normal startup in MSCONFIG
Windows 11/10 stuck in Selective Startup
MSConfig offers three modes— When Windows gets stuck in selective startup, then even when you select the Normal startup option, the option may change to the Selective startup option when you restart your computer.
If Normal startup reverts to Selective startup as MSCONFIG cannot select or save settings after reboot, then try this:
Type MSConfig in the Run prompt (Win +R) and press the Enter key.Switch to the Boot tabClick on the Advanced Options button.Clear all the that is selected thereClick on the OK button.Restart the computer, and now everything should boot normally.
Microsoft mentions that the Normal startup option reverts to Selective startup if you select any of the options in the Advanced Boot Settings dialog box in MSCONFIG. This behavior is by design. Additionally, if any of the System Services have been disabled or changed from their default value, the computer will set the startup type as Selective. Switch to the Services tab, and then check if you have anything disabled under the Date Disabled column, and enable it. If this does not help, you may boot Windows in Safe Mode and try to make the changes and see if that works.
Selective Startup is not a bad thing. Most of the time, many services start as the computer starts, and this diminishes the system performance. It helps you troubleshoot. If you are facing a problem, you may have to go through the list one by one, and check if the particular service or option is disabled or checked, and change it. I hope the post helped you understand why the startup mode kept changing, and now you can boot normally.
