Windows 10: Random Lockouts

My daughters laptop keeps locking her out. It is using her Windows Live account and frequently decides the password is no longer valid. It is running Windows 10. It is a standalone machine, not on any networks (except home Wifi). I have now reset it numerous times, changed it back to the original password but same happens again. The laptop is almost unusable because of this issue and the reset taking 20 minutes each time. The laptop is only 14 months old. Any help / guidance welcomed.

Random BSOD while browsing internet


BitDefender is nothing special. mwac.sys causes BSODs anywhere.
A tiny documentation can be found here: Solved Random BSODs - Windows 10 Forums
In that very thread, the suggested action apparently worked.

The storage and network filters of any third party antivirus can cause BSODs. Neither MBAM nor BitDefender is any special. For a regular antivirus, it may be shifted to an alternative; but MBAM has no alternative. So a clean install of the said program is the most feasible first step.
As far as the first step is not failing, it is better to not think for the second step. Because the BSODs are not universal, failure at the first step is not universal; and success at the second step is also not universal.
That is why I posted that my suggestion may work, or may not. Let us see where it goes.

 

random restarts

Hi,

If a Windows computer random restarts, the device usually have some damaged system components. For us to provide an accurate solution, we would need you to answer the following questions:

• Which build, version and edition of Windows is installed on your computer?
• What changes have you made to the device before this issue occurred?
• What troubleshooting steps was already performed to your laptop?

In the meantime, it will be best to make sure that the latest update of Windows is installed on your device. If the same issue happens after installing Windows Update, we suggest running the power troubleshooter. To do so, follow these steps:

• Open the Control Panel.
• Using the search bar at the upper-right corner, type troubleshooting.
• From the search results, click on Troubleshooting and then select System and Security.
  
• Click on Power and then follow the prompts to successfully run the tool.

We are looking forward to your response.

 

Account Lockout Policy is not working


Hello guys,

I have Windows 10 Enterprise build 10240 on my Dell Tablet (32 bit) and Oracle VM (32 bit). On both system, I tried to setup Account Lockout Policy in Local Security Policy. I have Account Lockout Threshold = 5, Lockout Duration and Reset Lockout Account Counter = 30 min. However, after locking my account or signing off, my account is not locked after 5 and more failed logon attempts. This feature worked correct on my Windows 8.1 system with the same account lockout settings.
Does anyone experienced the same behavior? Any explanation or fix?

Thank you very much,
