I've went into the hidden applications folders an directly & indirectly messed it up . All my own doing .
Don't ask me why I did this; I don't have a good answer. Everything else functions otherwise, I still have access to Cortana, and the OS is snappy.
So specifically Maps ( I like offline Maps ) , Store, and Calculator ( I also used the Calculator a lot ) ;
Win 10-Photo viewer , and a Bing Application or two
( Finance , etc ) are not functioning
( will not appear , or missing ) .
Mostly a domino effect, from intentionally removing other Apps , which played on others. Example, if you were to remove Groove Music, it will effect iHeart radio. etc.
( I didn't remove Grove Music ).
The Store and X-box App ; I completely deleted ; all of their files are not present anymore .
(( I used a combination of third party applications to locate and delete files ;with View Hidden files checked , I used - Unlocker, Revo Uninstaller-( which gets files, and registry entries ) , Search Engine Everything and Space Sniffer .
I added Unlocker, to the right click menu through the registry , which allowed for deleting of files in bulk . Run as administrator , etc. Folders I could not access; I could through the Unlocker window.
Then sweep up with CCleaner, which Windows tends to try and prevent from running . ))
But if you want Maps to function, and update, you need The Store as far as I know.
After deleting the Xbox app the Windows Update errors began . So Windows 10 builds wont update.
But ; I don't want the Xbox app back.
I think if I have a copy of some of these folders ; perhaps I can put them back , and these applications will work again.
I believe System restores ( non early enough ), and Update & Security > Recovery > options cant work in my case without risk of the system not turning back on again ; because of Missing files . I've tried the base recovery, where personal files are not effected , yet that was not able to complete because of the corrupted and missing files .
...Windows 10 Home - Version 10.0.10586 Build 10586 ...
The Update & Security > "" Windows Update "" has a corrupt files error code : I cant updated the build versions I'm at; seems to be.
Accounts > ""Your email and accounts "" window wont load.
( Accounts is important, as Cortana needs access to one to function ; So I almost lost Cortana , but Managed to avoid that, but I cant recall how >
I Think by creating another account on the OS, accessing Cortana from there with the same outlook email account; then switching back. Perhaps that did it. )
Ideally - I'd like access to Maps ; Calculator and The Store , The Windows Updates
and Your email and accounts window working .
I've tried making another account within the OS : Some of these options appear to work there ; Maps, and email and accounts menu , But updates will not apply there either same Error code: (0x80073712) .
Even where you'd choose default apps, there are letters in its place: " TWINUI " .
I've tried copying the Maps application folders from that account, migrating them over to the corrupted account , but with no clue' I'm unsure where to place these files again.
I've since deleted the test account. But will make another attempt ; if only to get the calculator and Map files.
Its easy for me to get into these folders and extract files and delete them all .
I've actually completely deleted Internet Explorer : that seems to have Not any adverse effects on Windows 10 ( clean up after with CCleaner . Edge still works .
But I notice its harder to place files Into the same Windows Application folders , it wont allow the placement. I figure a 3rd part application can help place those files for me .
