A Secure Boot certificate 2023 check on Windows 11 or Windows 10 takes about five minutes, and the PC keeps booting whatever the answer is. As I have been reading and hearing about this Secure Boot certificate expiration, I thought to check my home and office PC to confirm where my PCs stand. In this guide, I’ll show how to read the answer from the Windows Security app, PowerShell, the registry…
The Windows update is sometimes a nightmare, especially on the business/work network. If you have direct internet without any proxy or WSUS servers, it will work without any issues most of the time. That is how it works on personal computers at home. But when there is a complicated setup with the different versions of servers, multiple Internet gateways, and proxy servers, you will face random issues with Windows updates. Recently I had a problem with Windows 2016 server where the Windows update stuck at 0% and did not move further. A server that sits at 0% in Windows Update…
The MSOnline and AzureAD PowerShell modules are gone. MSOnline was retired in spring 2025 and AzureAD stopped working from mid-October 2025, so any old script that starts with Connect-MsolService or Connect-AzureAD now fails. Microsoft Graph PowerShell is the replacement, and it works differently enough that your old habits will trip you up. In this guide, I’ll show how to install it properly, connect with only the permissions you need, and run the everyday Microsoft 365 admin tasks: user lookups, licence reports, stale accounts and group members. Further down there is a cmdlet mapping table for old MSOnline/AzureAD scripts, a short…

Also check you are on the router’s own network, use http:// and not https://, and turn off any browser proxy. Knowing how to access the Internet router/Wi-Fi Access point admin configuration page at your home or organization (if you have permission) is always useful to manage many related settings. Let us discuss the reasons and solutions if 192.168.1.1 is not working or not opening for you. Accessing the router login page will…

macOS 27 Golden Gate does not install on any Intel Mac. If your Mac has an Intel chip, Tahoe (macOS 26) is the last version you can run, and that also caps the macOS virtual machines you can build on it. In this guide, I’ll go through the macOS 27 Intel support cutoff, your options for an Intel Mac, what changes for macOS VMs, and what the end of Rosetta 2 means on Apple silicon. Short answer: macOS 27 Golden Gate needs an Apple silicon Mac (M1 or later). Intel Macs stay on macOS Tahoe 26 and keep getting security…
When you copy some text on your Samsung phone, where does it go before you paste it? It goes to your phone’s clipboard. But where is the clipboard on my Samsung phone? The Samsung clipboard lives in the Samsung Keyboard. Tap any text box, then tap the clipboard icon on the keyboard toolbar. If you don’t see the icon, tap the three dots (or the arrow) on the toolbar and choose Clipboard. You can also tap and hold a text box, or use the Edge panel. Everything you copied, text, links and images, is listed there. If you’ve been copy-pasting…
Windows 11 24H2 end of support for the Home and Pro editions lands on 13 October 2026. After that date these PCs stop getting security and quality updates.

In this guide, I’ll show how to check your version, which version to land on (25H2 or 26H2), and what to…
