In its security updates Patch Tuesday, Microsoft has added a new option to Windows that allows system administrators to disable JScript in Internet Explorer.
Over the years, malicious users have realized that they could attack JScript, as Microsoft did not update it frequently.
Now, 11 years later, Microsoft is finally giving system administrators a way to disable JScript by default.
According to Microsoft, the Patch Tuesday October 2020 brings new keys to the Windows registry that system administrators can change to block the jscript.dll file.
How can this happen:
Open run with search, and type regedt32 or regedit.
To turn off JScript in Internet Zone, you need to find the following key in Registry Editor:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Internet Settings \ Zones \ 3 \ 140D
Locate the following subkey in Registry Editor:
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Internet Settings \ Zones \ 4 \ 140D
Right-click the registry subkey, and then click Modify.
In Edit DWORD (32-bit) value, type 3.
Click OK, and then restart Internet Explorer.
