Accidentally deleted the path of environment variables

I accidentally deleted the path of system environment variables, instead of editing it and adding a new one, in my Windows 10 Dell Laptop. I lost all the default variables that were there. How do I restore the previous variables? Please help

Hi,

Corrupted file system may be the reason why you're unable to perform system restore. To assist you better, we'd like to know if did you get any error messages when you tried to perform the system restore.

Meanwhile, we suggest that you follow these steps to do the Repair Mode:

• Tap F8 at boot time.
• Select Repair Mode.
• Select the System Restore option.
• Set Windows back by a few days.

Keep us posted if you need additional help.
