My Windows 10 preview pane in Explorer is not showing the preview for regular .txt files. It simply displays No preview available.

How do I fix this?

Much late, but you just need to modify the registry:

Copy everything between the --- and the bottom --- and save it as restore_txt_preview.reg then double-click it, and answer yes or okay to everything.

--- start copy below this line

Windows Registry Editor Version 5.00

[HKEY_CLASSES_ROOT\.txt]
@="txtfile"
"ContentType"="text/plain"
"PerceivedType"="text"   

[HKEY_CLASSES_ROOT\.txt\PersistentHandler]
@="{1531d583-8375-4d3f-b5fb-d23bbd169f22}"

[HKEY_CLASSES_ROOT\.txt\ShellNew]
"ItemName"=hex(2):40,00,25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,\
  6f,00,74,00,25,00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,\
  00,6e,00,6f,00,74,00,65,00,70,00,61,00,64,00,2e,00,65,00,78,00,65,00,2c,00,\
  2d,00,34,00,37,00,30,00,00,00
"NullFile"=""

--- end copy before this line

  • Sorry, the formatting on this page moved the Windows Registry editor line to the same one as the "copy from here" but it is where you should begin copying the text. Feb 6, 2018 at 3:07

  • Windows Explorer only shows previews for bitmap files for me, but not for documents like Word, PDF, Text. Grateful for any other ideas on how this could be fixed.

What worked for me:

Hold down the Windows key and type r

Type regedit, then hit enter

Choose HKEY_LOCAL_MACHINE\SOFTWARE\Classes

Scroll down until you find .txt

Right-click and choose New -> String Value

Type PerceivedValue and hit enter

Right-click the new entry you just created, and choose Modify..

In the "Value Data" box, type text and hit enter
