Since then there has been a major upgrade to Windows 10 and the powershell to re-install apps now breaks them. Even this forum still has Turorials suggesting you run it (not sure why).
It is just one of those things - time passes, things change.
Best you open another thread (and don't try re-installing apps with powershell without backing up first).
Really though any of this this should always be a test fix. Perhaps it will work, perhaps not. You can't just run any old script you read on the internet and assume it will work.
I had been hoping Microsoft would have issued a fix for the November bug by now, but as January comes towards an end without anything from them it looks unlikely. I am not often prone to criticising them, but this has been a bad business. I fear I am going to have to get my head round a re-install, as some users have recommended. I follow quite a few different forums in which I have not encountered a single example of someone resolving the issue other than by re-installing.
I think it may be worth explaining how I came to be caught by the PowerShell app re-registration trap, as someone who had never used PowerShell before. It was as a result of using the FixWin 10 Tool produced by The Windows Club. One of its features is the procedure to re-register app(s) with a PowerShell command, which I hoped would repair a corrupt Calendar app. The rest as they say is history. My Calendar app is still in need of repair, to which is added the Store, plus a large number of important Microsoft apps which are in an even worse unusable state, and several third-party apps aswell.
I have started reading up regarding my impending re-install and already have questions in addition to the ones above --- the info I have found is far from clear:
1. Is the MCT the same thing as the Windows USB/DVD Download Tool, under a different name?
2. Much of the documentation just refers to Windows 7 --- do I take that download process detects what Windows OS you have and are intending to re-install?
3. "Before you run the Download Tool, make sure you have purchased the Windows ISO download from Microsoft Store and downloaded the Windows ISO file to your drive." What does this mean? What 'purchase'? It is not possible anyway, because a totally broken Store is one of things for which the re-install is intended as a remedy
4. the 'Missing Manual' says not only are the third-party apps / programs lost but also most drivers, which will have to be found and installed again
5. Is it still the case that USB drives larger than 8 GB will not work?
#1 Basically yes. I use Rufus though because I made my Windows GPT partitioned (allows UEFI) not MBR. If you're not familiar with those terms you need not concern with them and just do what you normally do.
#2 MCT also knows Windows 10
#3 Microsoft Store =/= Windows Web Store. 2 different platforms. But since Windows 10 is free, you should be able to get the ISO from Microsoft somewhere. I believe MCT actually downloads it for you.
#4 True and true. But Windows 7 onwards has its own large library of known drivers so everytime you plug something in it will just recognise it more or less. What you should do though is this. Get your network drivers downloaded before hand and have them ready after the Windows install. Once you install the network drivers you're good to go and Windows will download the rest that it needs.
Hope you have an easy time. For me, the Web Store not functioning is just something I can live without so it doesn't bother me so I don't want to go down the reinstall path. The issue is still there though, I was fortunate enough to be able to use a Restore Point to bring back the functionality of the basic apps like Calculator and such.
Yes, you are right. The November Update has a bug that breaks windows apps when we try to fix it through the Appx cmdlet using PowerShell. In fact the Appx commands reinstalls the Windows Apps correctly, However, due to the bug, it also immediately deletes a folder within the Windows apps folder that is required for the respective Apps to launch successfully. If that deleted folder is replaced for each app that is broken, It will be up and running.
I spent quite some time trying to figure out what is happening and was able to finally get to the solution. The logic is simple, replace the missing folders back into the windows app folder. We need to follow a systematic approach fixing it. It could be the ultimate solution, until Microsoft Fixes it. I have posted the walk-through step by step in my Blog techtantri. Please check it, it would surely be helpful for our Windows 10 Community. I had also provided a fix for reinstalling edge browser which was shared in this forum by Slugger.
I can help guide you to fix the calendar app and all other Windows Apps without having to ever re-install Windows for these issues. Please post here, the symptoms of the issue as well as the steps that you had already followed trying to fix it. It will usually take no more than 5 minutes to fix the calendar App.
Download the missing Windows App files from here and then just copy and paste it into the C:\Program Files\WindowsApps Folder. You need to take ownership of the Windows App Folder to let Windows allow you to paste it.

^ does this guy sound like a spammy robot or what? The blog post looks legit though.
