USB Type C, USB Type A and Canon scanners–they do not work.

My (newest) Canon scanner has a USB Type C (USB-C) plug.

The supplied cable is a USB-C to USB Type A cable.

My laptop only has USB-C.

So I thought, I’ll just use a short USB-A to USB-C adapter:

Seems like it would work.


You can’t go USB-C –> USB-A (adapter) –> USB-C.

The scanner seems to have power and/or timeout issues.

The solution is to either a) use a USB-C –> USB-C cable or b) use a laptop with a USB-A port.

Why writing is blocked to C:\Program Files, and some other locations.

It’s the Data Redirection feature that was introduced with Windows Vista, in November 2006.

Data Redirection – beginning with Windows Vista, standard users have restricted access to certain files, folders, and registry keys. When an application is trying to write to these locations, it gets redirected to somewhere else. Most of the time this is transparent to both users and application developers, but sometimes it is not and that lead to some very interesting results.

The strange case of … Applocker blocking

Applocker blockOn our “standard” workstations we have enabled Microsoft Applocker, which blocks unauthorised software from being installed.

We also have “Unrestricted” workstations, where there is no Microsoft Applocker, and customers can install anything they want.

All our workstations start out as “standard” workstations, and get moved to “Unrestricted” when a customer explicitly requests it.

We do occasionally encounter the issue where Applocker Rules are Still Enforced After The Service is Stopped.

Our fixes are as follows.

Option 1

  1. Apply the Solution from Applocker Rules are Still Enforced After The Service is Stopped

Option 2

  1. Stop the Application Identify service
  2. Delete the SrpV2 registry key and entries under HKEY_LOCAL_Machine\Software\Policies\Microsoft\Windows
  3. Start the Application Identify service
  4. Have the customer reboot the workstation.

Option 3

  1. Stop the Application Identify service
  2. Delete the SrpV2 registry key and entries under HKEY_LOCAL_Machine\Software\Policies\Microsoft\Windows
  3. Start the Application Identify service
  4. On the workstation, perform a gpupdate /force
  5. Have the customer reboot the workstation.

Normally one of those options will work for us.

“Logon failure: the user has not been granted the requested logon type at this computer”

CustomCPZoomedQuick answer:
In Windows 7/8/10, we use a third-party Credential Provider, and it was blocking LOCAL (ie. not Domain) accounts from logging on.  Removing the third-party CP resolved the issue.  (we have logged a fault with the vendor).

Today I learnt about FIPS and SHA1

Sha-familySystem.InvalidOperationException: This implementation is not part of the Windows Platform FIPS validated cryptographic algorithms. at System.Security.Cryptography.SHA1Managed..ctor() at ....

When I say “learnt”, it was more about reading documents to determine what happened to cause the above error.

I suspect either of these:

  1. Microsoft have released a new schannel.dll which removes and/or breaks SHA1 functionally.
  2. The Group Policy setting “System cryptography: Use FIPS compliant algorithms for encryption, hashing, and signing” has been enabled.

My quick “fix” was to change the application to use a different hashing algorithm.

How to grab an Windows Store APPX file so you can install it offline.

I thought I’d have to do this for the Surface Pro 4 “Pen” application, but Microsoft has bundled the Pen application into Windows 10 Anniversary Version (Build 1607).


The Windows OS Hub has written a comprehensive guide on how to do this.

Modern Windows 8 apps (APPX Metro apps) are mostly designed to be installed online from Windows Store. Despite Windows allows to install Metro apps from APPX files offline, you can’t download a Metro app distribution from Windows Store. In this article, we’ll show how to download an APPX file of any Modern App using Fiddler and install it on the systems with no access to Windows Store (offline systems or corporate computers).

So, our task is to get an archive with an APPX file of any Windows 8 Metro app to install it manually on an offline system. As it has already been told, you can’t directly download an APPX file from Windows Store. However, during the installation of any app, at a certain moment a client gets a generated link to download its APPX file. Let’s try to trace the link, by which Windows Store downloads an installation file.
