How to turn off Mysterious Blue Double-Arrows Added to Windows Desktop File & Folder Icons

To remove compressed file/folder icon overlay (double blue arrow) without decompressing files.

• Download empty.ico

• Copy "empty.ico" file to "C:\ProgramData\empty.ico".

• Open regedit.

• Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer.

• Right click on \Explorer and using the dialog menu choose New > Key and name it Shell Icons. Press Enter.

• In the right pane of Shell Icons, right click on an empty area, and click/tap on New and String Value. Name it 179.

• Double click/tap on the 179 String Value to modify it. You should see a blank box called Value data.

• In the Value data box enter (or copy and paste): C:\ProgramData\empty.ico and hit OK when done.

• Restart explorer or log off/on or restart PC.

• Done.

• If you want to remove shortcut overlay on icons ,  instead of "179", use "29" for String Value as in the image above.
