Windows 10: Open in another program

Hello.
I'm running into problems regarding deleting, moving or re-naming files/folders ... always PDF ones.
"...file is open in another program". There is no other program open!
In Task manager it sometimes works to end Adobe Collaboration Synchronizer (2), but sometimes the problem persists.
View is on List, so no thumbnail.
What program is the culprit? And just closing it every time - or even rebooting - is not a solution.
Is there a permanent fix?
Obviously I searched but with no avail.

Thanks in advance

Windows version 1909, latest .. always uptodate

:)

 

Why did the startup window get cleared?

I didn't missed any step, the list was gone and gone , even after using lot of programs the programs were not listed in that list.

 

Lost default photo viewer after profile rebuild


Thanks Brink. I've tried those steps before i started searching Google. After the profile rebuild i don't have the Photo app listed to choose to make it default in either the system settings for default apps or the Open With option.

I can't even find it doing a search. Seems to have been removed somehow with the profile rebuild, which doesn't make sense.

Might be helpful to list what i've done I've done the open with check, the choose default program in the system menu, tried that in device manager default programs also. I've checked the programs and features Turn windows features on/off and it's not listed there (never thought it was but that was a suggestion), searched the MS Store, it's not listed there either.

I don't like playing in the registry unless i have defined steps and haven't found anything for this yet, just the Win7 version like in my OP.

 

Mail app will not open on 10041.


Hello Adam,

This is the suggested solution below if you haven't already tried it.

In this Windows 10 build 10041, the Mail, Calendar, and People apps may be broken due to a licensing issue with the Store Beta. To get these apps working again, you need to follow these steps:

• Open powershell as administrator
• Run the command Get-appxprovisionedpackage –online | where-object {$_.packagename –like “*windowscommunicationsapps*”} | remove-appxprovisionedpackage –online
• Re-install Mail, People and Calendar from the Store (green tile)
