Windows 10: Windows Store Apps "The Parameter is incorrect" Error on startup

Hi,


Yesterday I decided to change the ownership of my Windows partition from Trusted Installer to me. and then I made Trusted Installer a user with full control and me a user with full control also added the All Application Packages user with full control along with the system user and the admin user.


Then I all users audit ability including the admin and system, all of that was done on Safe Mode.


Now everything is working fine except for Xbox Beta, Itunes, Icloud, Intel Graphics Command Center, I get this error when I tr0y to open them.


is there a way I can fix this error?

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

 

All Windows Store apps report "The parameter is incorrect"

It all began when I was trying to get Firefox to open a downloaded Word .doc file. Firefox absolutely refused to realize that I had Word installed. So I did what I usually do when Firefox is obstinate about opening a file; I tried to locate Winword.exe and manually associate it with .doc files. Except I couldn't find Winword.exe anywhere.

I finally found it in a folder I had never seen before, "C:\Program Files\Windowsapps". The problem was that the folder was hidden and had some very strange permissions on it. So I took ownership of the folder and all subfolders and gave myself full control. That was a mistake.

Now when I open *any* Windows Store/Metro app I get the message "The parameter is incorrect". How can I repair the permissions on "C:\ProgramFiles\WIndowsapps"? I've already given ownership back to "TrustedInstaller", but I'm still getting "The parameter is incorrect." I also tried "sfc /scannow" but that didn't help.

BTW, all "classic" desktop apps work fine and Windows boots without any issue. But Office365 is totally hosed...

 

This Parameter is incorrect 0x80070057 win 10 recovery cd-rom

Hi,

The error "This Parameter is incorrect" usually happens because of a system or disk errors. To isolate this issue, we suggest running CHKDSK using the command prompt. Running CHKDSK
can check the integrity of a hard disk and can repair various file system errors. To run CHKDSK follow these steps:

• Plug in external hard drive, USB drive or memory card to the computer.
• Press Windows Key + X and then select Command Prompt (Admin).
• In the Command Prompt window, type chkdsk E: /f /r. You should replace E with the drive letter of your external hard drive or external device.
• Restart your PC once the process is done.
