Remove cached passwords on Windows

Windows caches your user names and passwords entered for network shares, drives etc. That’s fine until there’s an incorrect password or username in the cache, and you want to remove it.

The utility to delete cached credentials is hard to find. It stores both certificate data and also user passwords.

Open a command prompt, or enter the following in the run command:

rundll32.exe keymgr.dll, KRShowKeyMgr


Disable windows 10 non enterprise store tab’s

With the new Windows Store for Business, organizations can make volume purchases of Windows apps. The Store for Business provides app purchases based on organizational identity, flexible distribution options, and the ability to reclaim or re-use licenses. Organizations can also use the Store for Business to create a private store for their employees that includes apps from the Store, as well private Line-of-Business (LOB) apps.

For a Windows 10 project that I am currently  working on we wanted to disable the non enterprise store tabs in the windows Store app and only use the Windows store for business!

Current situation, logged in with an business user account:


According to Microsoft, The only way to disable the non enterprise store tabs right now is a mobile CSP. Supposedly, a GPO for this is forthcoming, but not available yet. If you disable the store with the GPO, the private store goes with it!

Well this is not completely true because I managed to find the right registry key to accomplish this. see below for the result:


To fix this the only thing you need to change is one registry setting, assuming you already configured Azure AD and Business store of course!

Using Registry Editor
Run regedit and hit Enter to open the Registry Editor. Navigate to the following registry key:


Change the DWORD VALUE in the RequirePrivateStoreOnly key  from 0 to 1.

Restart you windows Store app and you should now only see the business store! If you arent’t logged in with an business account then you only see a grey window!

I hope this was informative for you!

This setting is tested on a Windows 10 enterprise (Build 10586.164).

Kind regards,
