"ADV200006 | Type 1 Font Parsing Remote Code Execution Vulnerability", a zero-day vulnerability in the Windows 7, was reported on 2020-03-23, which is said to be less effective in Windows 10.
As one of the workarounds, Microsoft suggests to:
Disable the Preview Pane and Details Pane in Windows Explorer
Ones of the easiest ways are to use the shortcuts in Explorer with your keyboard:
- Alt + "P" toggles "Preview Pane".
- Alt + Shift + "P" toggles "Details Pane".
By the way, here are the ways to use command lines to edit registries.
They are suitable for automation and bulk batch execution.
Caution: Editing registries in wrong ways can break your computer.
First, run command prompt as an administrator.
For example, press Windows + "R" to open the "Run" box, type "cmd" into it and then press Ctrl + Shift + Enter. You'll get the prompt after permission's asked.
NoReadingPane value as DWORD and set 1 as its data in it as below:
reg add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer /v NoReadingPane /t REG_DWORD /d 1 /f
Note: "HKCU" means "HKEY_CURRENT_USER".
/f is an option to overwrite the value without confirmation.
Once you sign out and sign in again, the Preview Pane in your Explorer will be disabled.
How to restore it
reg add HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer /v NoReadingPane /d 0 /f
IconsOnly value's data as below:
reg add HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced /v IconsOnly /d 1 /f
Once you sign out and sign in again, the Details Pane in your Explorer will show just icons instead of rendered content like thumbnails.
How to restore it
reg add HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced /v IconsOnly /d 0 /f
Here, the two panes are disabled.
The Explorer looks like this.
