Windows 10: How to reinstall/repair microsoft store, windows security center and app installer windows 10

When i was upgrading to windows 10, the electricity went out and after a while, my laptop shutdown, now i seem to not be able to use Windows Security center, microsoft store, app installer and can't even install things via powershell adminis there a way to sort of reinstall them without losing my apps in the process? Will installing the .iso with media creation tool onto an USB, and using the system image recovery delete my apps?

Microsoft Adds Ability to Block Win32 Apps from Install on Windows 10

Totally agreed with the editorial, personally I have a phobia for apps, they take the control away from you. Taking about security risk, what about the apps of the Windows store that are in themselves a security risk, and if so, will Microsoft takes responsibility for that. In my newly install Windows got crippled by Windows apps, namely I cannot update the graphic driver, and I cannot restore Windows to an early point. It costs me A$150 to get it check out. And I am advised not to any of the Windows apps in the meantime, until Windows store got the fix. But they've never informed you that Windows store got corrupted in the first place, how are they going to inform you it got the fix?

 

[Solved] Windows 10 keeps reinstalling KB3119142

I noticed quite some time ago that KB3119142 (Update for Microsoft Visual C++ 2012 Update 4 Redistributable Package) kept reinstalling itself for some reason. At least once daily. Sometimes up to several times a day. I just ignored it. It didn't seem to be doing any harm. And I figured they'd eventually fix it. Well...days turned into weeks, weeks into months, with no end to the problem in sight. It dragged on unsolved for at least the last few months. Literally reinstalling itself hundreds of(at least a hundred, felt like more) times in that period of time.

So I finally googled it a couple days ago. And just got around to fixing it today. Which appears to have worked. And it couldn't have been easier to do. I feel so stupid to have let it intimidate me for so long.*Oops!

Below are links to the thread that I got the fix idea from, and the official MS support info page for KB3119142(from which I quoted the above).

Windows 10 Tweaks

As you may already know, Windows 10 (as well as Windows 8) allow you to log in with a valid Microsoft account, instead of creating a local account that only works on your machine. However, you may prefer to keep a local account for privacy reasons. If you do, though, some Windows 10 features—like Cortana—may not work. Despite the default behavior, the Windows 10 Store is not one of them. You can still log in to your Microsoft account for just the Store without switching to a full Microsoft account. The process, however, is not terribly obvious. To do so, follow these steps:

• Launch the Store from your Start menu.
• Click the user icon next to the search box.
• Click “Sign-in” from the menu that appears.
• Choose “Microsoft account” and log in like normal.
• When the “Make it yours” box appears do not enter your password. Instead, click “Sign in to just this app instead.”
