Labels: Issue-Bug,Priority-2,Product-File Explorer

### Microsoft PowerToys version

0.62.1

### Running as admin

- [X] Yes

### Area(s) with issue?

PDF Thumbnail

### Steps to reproduce

1) Have the PDF thumbnail feature of Power Toys deactivated. Have the PDF Preview Pane feature also deactivated, just for the sake of certainty. Restart computer. Make sure that now PDF thumbnail (and PDF preview pane) is correctly as expected NOT handled anymore by Power Toys.

2) Install, activate, and use another software that handles PDF thumbnail (by chance it could also simultaneously offer or even directly package the function to handle PDF preview pane, choose this also if you can do it separately) in Windows 10's File Explorer. To be exact with my case, have the one that comes bundled with (the installation of the PDF reader app called) [Sumatra PDF](https://www.sumatrapdfreader.org/free-pdf-reader).

3) Restart computer. Make sure that the software in point 2) above now (after restart) handles PDF thumbnail correctly as expected.
Observe or expect, that from now on, the software in point 2) above shall be the only one that handles PDF thumbnail, except when (and only when!) it's overridden **by user** with another software.

4) Update PowerToys to the next offered version very normally and intuitively from within the app ; nothing "fancy" like updating through any other means. Keep in mind, that the PDF thumbnail feature of Power Toys (and the PDF Preview Pane feature also), in accordance with the point 1) above, was deactivated before the update.

5) Observe, that the PDF thumbnail feature of Power Toys (and the PDF Preview Pane feature also) still stays deactivated after the update (which is the correct behavior). Restart computer.

6) Make sure, that there aren't any external factors that could've interfered with this reproduction process. E.g. doing some meaningful things in regards to PDF thumbnail / preview pane that aren't defined in these steps, activating/deactivating (either directly or indirectly) another software that handles PDF thumbnail / preview pane that isn't mentioned here, etc.

7) Observe, that now the software in point 2) above doesn't handle PDF thumbnail anymore. I suspect, something of this sort could've happened "behind the screen" : With the update process of Power Toys, Power Toys' PDF thumbnail (and PDF Preview Pane) function _somehow_ overrides the software in point 2) above, and then makes itself deactivated upon the completion of the update process to conform with the user's configurations before the update. Hence the end result, that the software in point 2) above now doesn't handle PDF thumbnail anymore.

### ✔️ Expected Behavior

As per the realm of the reproduction steps above, the software mentioned in point 2) there shall still handle PDF thumbnail (and PDF preview pane), even after Power Toys updates. Keep in mind, that the PDF thumbnail (and PDF Preview Pane) feature of Power Toys is always in the deactivated state. If these features are deactivated, they shouldn't interfere howsoever anymore with Windows 10's File Explorer's PDF thumbnail and PDF preview pane, at least that's what I expect from the user's point of view.

### ❌ Actual Behavior

After Power Toys updates, as per the realm of the reproduction steps above, the software mentioned in point 2) there doesn't handle PDF thumbnail (and PDF preview pane) anymore. Keep in mind, that the PDF thumbnail (and PDF Preview Pane) feature of Power Toys is always in the deactivated state. If these features are deactivated, they shouldn't interfere howsoever anymore with Windows 10's File Explorer's PDF thumbnail and PDF preview pane, at least that's what I expect from the user's point of view.

I suspect, something of this sort could've happened "behind the screen" : With the update process of Power Toys, Power Toys' PDF thumbnail (and PDF Preview Pane) function _somehow_ overrides the software in point 2) of repro steps above, and then makes itself deactivated upon the completion of the update process to conform with the user's configurations before the update. Hence the end result, that the software in point 2) of repro steps above now doesn't handle PDF thumbnail anymore.
