sdxhelper.exe (shown as Microsoft Office SDX Helper in Task Manager) is a genuine Microsoft file. It belongs to Microsoft 365 Apps, and the Office Feature Updates task starts it in the background. If it eats CPU, repair Office first. Disabling the task is the last option, not the first. In this guide, I’ll show what the process does, how to check that the file is not malware, and the fixes in the order I would try them. It applies to Windows 10 and Windows 11 alike, because the task comes with the Office build, not with Windows. What is sdxhelper.exe…
Picture a birthday dinner. Someone films a few seconds of everyone singing around the table, with just one lamp on, so the room is a bit dark. On the phone the clip looks okay. Then it lands in the family WhatsApp group and the first reply is, “why is it so blurry?” Fair question. Faces look soft, the cake is just a pale shape, and the banner on the wall can’t be read at all. Most people blame the phone camera. Honestly, the camera is only half of it. So here’s what really makes phone videos go soft, how an…
VirtualBox is slow on Windows 11 when Hyper-V or virtualization-based security is using the CPU’s virtualization feature (VT-x or AMD-V), so VirtualBox falls back to a slower mode and shows a green turtle icon. Turn off Hyper-V, Virtual Machine Platform, Windows Hypervisor Platform and Memory integrity, restart, and the normal “V” icon returns. VirtualBox slow on Windows 11 is what I faced when I migrated my home computer to new hardware. The VMs started working too slow, so slow that they were completely unusable. Even though the new hardware was more powerful than the old PC, it was a real…
If you built an Entra dynamic group with the memberOf operator to get “nested groups”, that group stops updating after 3 November 2026. It keeps whatever membership it had on that day, and nothing adds or removes users after it. In this guide, I’ll show how to find every memberOf rule in your tenant, then replace it with an attribute rule or convert the group to assigned membership. After 3 November 2026, Entra dynamic groups that use the memberOf operator stop updating and keep their last membership. Export your dynamic groups, find rules containing memberOf, then replace them with attribute…
If a backup tool, a Mac mail client or an old script suddenly lost its mailbox connection, EWS is probably blocked in your tenant. Microsoft is switching Exchange Web Services (EWS) off in Exchange Online one tenant at a time, and the way to keep an app alive until April is the EWSAllowedAppIDs list. Without that list, EwsEnabled set to True now blocks everything. In this guide, I’ll show how to check your tenant state, find the apps that still call EWS, write the list without wiping what is already there, limit EWS per mailbox and test the result. If…

The Microsoft Windows Production PCA 2011 certificate, the one that signs the Windows boot loader, expires on 19 October 2026. The other two 2011 certificates already expired in June. 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…
