Windows 10: start menu not opening and windows apps parameters are incorrect

hello,


so i recently created a steamlibrary folder on my SSD where my OS is. to do this i had to go in and change permissions from read-only to create this folder. basically, since then i cannot open the start menu and windows apps, like spotify and netflix give me an error "parameter is incorrect". i'm not sure what happened in the process but basically i feel like i'm stuck with reinstalling windows which i really don't want to have to do. i tried system restore but it told me there wasn't enough space and it wasn't succesful. any help would be greatly appreciated cuz i feel like there's an easy fix for this.

:)

 

GPU-Z what command line parameter ?

Current /? (-?) or / help (-help) parameter is invalid

 

Can I customize the list of suggest apps in the "Open with" menu?

You can't use it to add additional programs, only to set default programs.

Interestingly for me it shows nothing for text files:








Then if I want to add a portable app like Jarte Plus to open with context menu windows doesn't like it.





It's not present and is near impossible to add even via "look for an app on this PC"

OpenWithAdd to the rescue:




Result:

 

Can I customize the list of suggest apps in the "Open with" menu?

Well, I hope this helps the OP - it took a while. I tried 'Default Program Editor' (DPE) and it did indeed add (or remove) items, but when I tried to specifically add Word to pdf opening, it failed - it went through the motions, but nothing happened. So I started again, playing with settings for opening .doc files. This seemed to work: initially in explorer I had 3 programs appear in the 'default' list that pops up on a rt-click>open-with:



and this is what the relevant bit of the Registry showed:



Don't ask me why just 3 of those 8 (a to h) programs show up (maybe the 'instant' list is limited to three? - no, see later) - anyway, I used DPE to remove Wordpad from the list: when saving the edit as a REG file, this is what I got:

Code:

and the result in Explorer was:



and the registry now shows:



Note how item 'g' from the list has been removed (it seems there is no issue with having a letter missing). I then messed about trying to open a .doc file with various other programs, and they all started to appear in the 'instant' list:




So I thought 'well, that is easy - just open a pdf once in Word and it should appear'. So back to trying to open PDFs: but however many times I tried, Word would never appear.



even though there were any number of entries in the Registry 'Open With' list, including Word:



So what did DPE make of this - well, it showed some of the entries:



Although Word is shown, it doesn't appear on a rt-click. Its entry can be removed, but that doesn't help. So my attention was drawn to the existence of another folder below 'OpenWithList', namely 'OpenWithProgids', and that contained a specific ref to Sumatra (my preferred program for PDFs). Looking back at the same entry for .docx, I found this:



so I added an identical Word.Document.12 ref to the list for PDFs:



I think IrfanView is there as it got added during my experiments! I now get this in Explorer:


Hurrah! I then tried to use DPE to remove the redundant entries, and got this as a .REG file:
Code:

But when i merge that with the registry, the IrfanView item does not get deleted:



and as seen in the registry:



so I deleted it by hand, and at last have the entries I (or rather, the OP) want:




Note that my manually added reg entry is of type Binary', as there seems to be no way to add a value of type 'None'.

So it seems that DPE cannot cope with entries in the 'Progids' list, and something makes some programs fall into that list, rather than the 'openwithlist'. I am sorry for any typos above, or pictures in the wrong place - can't be bothered to check it too thoroughly. Hope it helps someone!
