Windows 10 IoT – Removing Windows Update history

October 29, 2020, 9:38 pm technology

Hi everyone

In my latest blog post I talked on how to patch a IoT terminal when the SSD is small.

A tip not talked inside the blog post is how to remove unnecessary files after the update.

I dont recommend that tip if you have plenty of disk space, as it will break for you some ability, like to remove Windows KB.

The command to use is;

Dism.exe /online /Cleanup-Image /StartComponentCleanup /ResetBase

I will quote the same warning than on the Windows website;

Warning

All existing service packs and updates cannot be uninstalled after this command is completed. This will not block the uninstallation of future service packs or updates.

By running the command I save a 1 or 2 gigs. It's not a lot, but on low disk space disk it mean a lot.

Thanks for reading, today was a small tip :)

Windows 10 IoT - Windows Update on small hard disk

October 19, 2020, 9:46 pm technology

Hi everyone

On IoT terminal often the hard disk is small, and there is a activity that can be a pain in such device, it's to install a cumulative update.

The last update I did I had in example 7gigs of free space, and the uncompressing of the patch did fill the space completely to make the update fail.

To show the problem you can see these printscreens, please remark the free space available;

capture11.png?w=761

capture12.png?w=753

In my example in my struggle to install the patch, which is by itself 1.6gig, I tried to run the patch from the network, but voila, it's not possible. You would receive such 0x80070003 error.

The tip I give today is to make an ISO with the patch, so you can mount the .ISO from a network share to trick the system.

I my case as Windows can't make the ISO natively, I got a free tool to make the job, wincdemu. A lot of other tool exist to make that work by the way.

After the tool is installed, you can just right click your update folder, and select the Build an ISO image option.

You can name the ISO like patch.ISO.

)

In the Windows after you can mount the ISO to run the setup from there.

![capture7.png?w=246](media://wp/2020/10/capture7.png?w=246
)

After it's mounted you can run the EXE.

At that point you can wait.

Windows 10 - Unified Write Filter - Quick tip for the monitor resolution

September 25, 2020, 3:51 pm technology

Hi everyone

Today I wanted to share a quick tip if you want to allow your users to set their own resolution.

By default the unified write filter allow some registry key, but when a user set a resolution, that setting currently impact all users sessions, so that specific setting is inside the HKLM.

As the seeting can change depending on the terminal you use, I would give you the tip to find the correct keys.

I used process monitor, and I log what SystemSettings do in the registry when you click to change the resolution, in example;

capture.png?w=901

As you can see, the registry key might be long, you can select to easilly copy it;

capture2.png?w=619

Inside the terminal after, add the exception for that registry key hive;

capture1.png?w=649

That will allow you user to set the resolution they want, and it will not come back to the default's one.

Thanks for the reading

Windows 10 build 2004 - Login script - Net Use Problem

August 31, 2020, 1:06 pm technology

Hi everyone

Today I wanted to share a small problem with Windows 10's newer build, 2004.

Login script that use net use no longer seem able to be used, the mapping no longer work.

To work around the issue you have two possible's way;

Add a timeout in the script's beginning;

timeout /t 60

or add a delete script first before the mapping;

NET USE * /DELETE /YES persistent: yes

Be sure that setting is set too, set it if not already before trying to make the workaround;

Computer Configuration

» Administrative Templates

» System

» Logon

» Always wait for the network at computer startup and logon

Some other mentionned that Enabling SMBv2 could help, but it all depend on your environnement, as in my case it happened between Windows 10 2004 client and a new DC in 2019.
