What to do when window 7 firewall has disabled

Do you have any type of internet security installed?

Go to start,in the search box type windows and it will show show you the firewall,click it and then go in and turn it on!

Hi Brence,

I am Aniesh from Social Media And Community at Dell.

You may enable the Windows Firewall Service in Services.msc by navigating to 'Properties' & also please set it to 'Automatic'.

If that does not work please run 'CMD" prompt in Administrator mode & then execute the following command.
SFC /SCAN NOW which will fix issues with Windows if any, post which you may try to enable the 'WIndows Firewall' service again.

Let me know if this answers your questions.
