Welcome to my little corner of the internet, where I've gathered all the nifty IT stuff that I find super interesting and useful. You will see my System Administrator notes, tips, and tools that I use based on my experience. These resources help me tackle tech issues with ease and boost my productivity. I truly hope you find these materials as valuable as I do. And hey, thanks for dropping by my little IT sanctuary. Alexander Reydman

Change number of monitors at Remote Desktop session
The connection settings are saved to a hidden RDP file in the Documents folder by default. So, you can also open this file with a text editor and directly edit the values there to set up the multi monitor remote connection. Here are the steps to do so:
- Navigate to the Documents folder and make sure Show hidden items is enabled.
- Open the RDP file with a text editor, add the following line, and then save the file:
use multimon:i:1
- If the display order is incorrect, execute the
mstsc /l
command in CMD to view all the monitors on your system. They’ll be listed as 0, 1, 2, and so on. - Next, you can adjust the values for the
selectedmonitors
line to rearrange the monitors in the correct order. - For instance, if you have 3 monitors listed as
selectedmonitors:s:0,1,2
, you could edit it toselectedmonitors:s:1,2,0
to change the display order, orselectedmonitors:s:0,2
to use 2 of 3 monitors. - Remember to save the settings once you figure out the correct order.

Golden rule -11
Updates are important!
Although there are occasions when updates cause a new problem to appear, generally speaking, they “help” more than they “hurt”. Not only do updates fix known bugs in software and operating systems, but they plug critical security holes that could potentially cause harm.

MailMaestro, your personal AI email assistant -great tool for people who not fluent in English
This post for MailMaestro. I've been using it at work for about a month now, and I have to say, it's the best program I've installed in the past year. It's been amazing, especially for someone like me whose English isn't perfect and who writes a lot of letters. The quality of my emails has improved significantly.
