Hello to all Windows installation freaks out there …

My name is Rainer Pollmann, I am a graduate engineer in electrical engineering and have been working as an ITPro since my university days. I started computing with 4 bit CPUs and earned my first money with the first IBM PCs (at that time with DOS).  

At university I had (among other things) a PDP11 and a microVAX as a „development environment“, each with punched cards (!) as program memory.

Later (1985) I developed a single-board computer with a Pascal compiler based on the Z64180 chip (CPU, MMU, IO, 8 bit) and used it to build (among other things) machine tool controllers.

A variant of it is still (!) flying around in several weather satellites in space 🙂

Another variant of it co-developed and built the booster housing of the ARIANE 5 rocket 🙂


I „got hold“ of the „Red Hat“ at a SUSE event and thus confess that I am also „good with LINUX people“ 🙂


After a longer time as a freelancer and as a technical manager of a small developer company, I have been working for a leading service provider in the industry for more than 20 years, there as a „Principal Technology Specialist“ with focus on troubleshooting and client deployment, and am retired now 🙂 

After about 30 years in the business, I’m starting an irregularly updated blog series about

„How do I get an enterprise-grade – AKA vanilla / signature image – Windows 10 client OS onto a fresh box, what tools do I use to do that & how do I troubleshoot it if something goes wrong in the process.“


„what do I do when & how if this is also going to happen in the AZURE cloud (cloud first)? „

Including some deep dive troubleshooting tips, but one thing at a time ….

I know & appreciate Michael Niehaus for many years, he has a very similar history as me.
Unfortunately he left Microsoft and went to Tanium and works now for 2pintsoftware:-(

Here you can find his famous OutOfOffice Hours Blog:

As a little appetizer to the stuff I’ve been doing for > 25 years in a big way:

Check out this video, it shows in fast forward the UPDATE (!) of a Windows 1.0 box (!) to Windows 10 🙂

SHORT Version:
Installing Windows 1.0 to 10 (Time Lapse) on a Virtual Machine – YouTube

If this video looks familiar to you or if you start to smile, you are right here 🙂

I will also try to continue the cool „Case of the Unexplained“ series by Mark Russinovich somehow, of course with using his tools 🙂
I also know Mark personally, he is „Mr. AZURE“ = Chief Technology Officer of Microsoft Azure – for some time now and (unfortunately!) hasn’t done such sessions for a long time 🙁

But his SysInternals tools are still maintained (and supported!) and I use them daily since the release of RegMon & FileMon 🙂

Let me surprise you 🙂

By the way, you can also reach me here:



„Doc Windows“ Rainer Pollmann


Digitalpate Rainer Pollmann

Since June 2023, I have been actively volunteering as a digital mentor in Ratingen as an advisor for senior citizens with smartphones and have also made a number of nice home visits in the meantime.

I will also be giving a few talks at various locations in Ratingen on the subject of using digital media.

I would like to pass on my know-how to this target group in a low-threshold way.

I am also the webmaster of this site.
