      If you’re not careful about naming your scripts then it’s often helpful to be able to ‘preview’ them from within (File) Explorer rather than have to open them in an editor.

      Here’s a QAD (Quick and Dirty) method of adding a Preview handler for different script types:

      1. Open the Registry Editor (using Run as administrator).

      2. Navigate (for example) to HKEY_CLASSES_ROOT\.ps1 and select it in the left-hand navigation pane.

      3. In the right-hand pane, right-click and choose the option New > String value.

      4. Rename the New Value #1 entry to PerceivedType.

      5. Modify the entry’s Data value to text.


      That’s it.

      To test, navigate within (File) Explorer and select a PowerShell .ps1 file. Use ALT+p to turn on the Preview pane.


      I’ve added preview handlers for .PS1, .AHK and .VBS files in both Win 10 and Win 7 so far (as these are all that I normally use).

      Note: I found that I couldn’t just import a REG file with the settings, either by double-clicking on a REG file or even running REGEDIT as Administrator and importing the REG file. I saw all the ‘normal’ prompts and messages that the import was successful… but nothing changed in the registry. The manual method is so quick that I haven’t (yet) looked into whether I can script the addition of the required entry.

      Hope this helps…

      Or right click on the file and Select “Open in Notepad++”.

      What do you mean you don’t have Notepad++ installed?

      cheers, Paul

      You can add to the registry in an elevated PoweShell window (or in a script), like this:

      $reg = @{
      Path         = 'Registry::HKCR\.ps1'
      Name         = 'PerceivedType'
      PropertyType = 'String'
      Value        = 'text'
      Force        = $true
      New-ItemProperty @reg
