VT-X virtualization has stopped working. What could be the problem?

Question

Android

Good afternoon!
I was prompted to write a question here by the brink of despair, which I approached over the past 2 days.
A couple of weeks ago I installed Android Studio on my ASUS N53SV laptop. Then, through the SDK Manager, I successfully installed HAXM and the emulator worked perfectly.
Then some winds in my head made me remove Android Studio along with the Android SDK.
Now when installing Android SDK, I can't install HAXM. Error VT-X is not turned on.
My percent supports virtualization, and it is enabled in the BIOS. But programs like Speccy show that virtualization is "Enable but Disabled".
Version of Windows 7 home basic x64. That is, I cannot disable Hyper-V through programs and components.
I checked my wife's laptop (some HP similar in parameters to mine, only Windows x86). The same "Enable, but Disabled". But after enabling the option in the BIOS, it became "Enable, Enabled".
Using the skills of Google-fu, I tried everything I found.
And back and forth in the BIOS I switched the value, and in Avast I turned off the "enable hardware-assisted virtualization" option, and tried bcdedit / set nx AlwaysOn and bcdedit / set hypervisorlaunchtype off, and all this together and in different combinations.
I even read somewhere that reinstalling Windows helped someone. I thought: "Well, I haven't reinstalled since the day I bought it. It's about time, I guess." And reinstalled.
The result is the same.
Only now I didn’t change the bit in the process, as they say in some guides. A little stingy. The laptop is still beloved-native)
I ask for help, but at the same time forgiveness if it seems to someone that my question is superfluous here.

Answer 1

I don't know what magic is. After trying everything I could (other than directly setting a bit in the processor), I installed VirtualBox as a friend suggested. And virtualization worked. And HAXM installed right away. And life no longer seems gloomy and hopeless.

Answer 2

run command prompt as administrator, enter the following command:
bcdedit /set hypervisorlaunchtype off
and restart your computer

Answer 3

Reset the bios to zero and turn it back on. Something strange though.
