Still Studying with a 2024 Microsoft GH-200 Exam Questions Guide?
If your GH-200 prep material is from 2024, I have some important news: that exam doesn't exist anymore. In January 2026, Microsoft made major changes to the GH-200 objectives topics were added, some were removed, and others were reworded. Most guides and pass reports online still describe the old version, which can seriously mislead anyone preparing right now. I took the exam recently under the current format and passed with 75% (passing score is 700/1000). Here's what caught me off guard: the new exam leans heavily into enterprise and security-focused scenarios. Areas like reusable workflows and passing inputs/secrets between them, workflow dispatch input validation, service containers, runner management (self-hosted vs GitHub-hosted, runner groups), and security topics like OIDC authentication and GITHUB_TOKEN permission scoping are now central to the exam. For preparation, I combined Microsoft Learn for building solid fundamentals with Certboosters' question bank for real exam-style practice timed tests and understanding why wrong answers are wrong. If you're prepping right now, double-check that your material reflects the January 2026 changes. It might be the difference between passing and failing. I've written a more detailed write-up of my full exam experience (environment, tips, exact topics). I'm happy to share it in the comments if anyone's interested and if that's allowed here. Has anyone else been caught off guard by the January 2026 GH-200 changes? What resources are you all using to prepare for the updated version?
dell Vostro upgrade to Windows 11
Hi Microsoft support community, I request your advice as I would like to install Windows 11 on my Dell Vostro 3590. Initially it was shipped with Windows 10 pre-installed and it worked perfectly. But I wipped the system to install another operating system (linux) and it worked also perfectly. Now I tried to install Windows 11 as I noticed the laptop is secure boot capable and this should be sufficient for Windows 11 install. But, I never made it trying to install W11 with USB. direct install or W10 upgrade did not worked. It get stuck on the logo screen. There seem to miss a driver for harddrive, so i tried to install several drivers from dell site w/o success. So I require your advice if it possible to install Windows 11 on a dell Vostro 3590. Thank you and have a good day,
Why does "COM Surrogate" block me from deleting files on Windows 11?
Why does a "COM Surrogate" prompt pop up every now and then when I try to delete certain files on my Windows 11 laptop, telling me the file is in use and can't be deleted? It only happens with some files, and sometimes after a restart I can delete them without any issue, then the next time the same thing happens again. My laptop is a Lenovo LOQ 15ARP9 with a Ryzen 7 7435HS and RTX 4060. Is this something serious, or just a normal Windows behavior that gets in the way? And is there a way to stop COM Surrogate from locking the files so I can delete them without rebooting every time?
Windows 11 25H2 Build 9457 lockscreen not changing picture
Hello to all, so, we have three laptops that have Windows 11 25H2 Build 9457, two of these have Enterprise whilst the third one has the Pro version installed, one of the Enterprise laptops is my work laptop, the other one I use for testing image installations etc and is freshly installed with this build. The Pro version is my personal laptop and has also been freshly installed. Ever since having the latest build installed on all three of these laptops, the lockscreen picture does not work, all three remain on the default blue bloom one. I have tried changing from spotlight to picture, restart, then switch to spotlight again with no success. I have deleted the contents of the Assets folder located under this folder MicrosoftWindowsContentDeliveryManagercw5n1h2txyewy , and also the settings folder, rebooted and had no success. I also tried the powershell script that registers the content delivery manager and had no success either I ran a dism check health and all three have no corruption detected, the same after running an sfc scannow. All this on three of these laptops. Then i decided to log on to the local Admin account of my work laptop and after a couple of minutes i locked the screen and the lockscreen picture changed I said to myself so it is working now, i signed out logged in with my domain account and the lockscreen defaulted back to the blue bloom picture. The same happened with the test laptop, i use a test domain user account for this, when i change to a local account the lockscreen picture changes, when i go back to a domain account it defaults to the blue picture. Also happens with my personal laptop where i use a microsoft account to log in. I am literally out of ideas what is causing this because using a local account makes the lockscreen spotlight work, when using a domain or Microsoft account it seems to break it. Thank you for any help.
Windows PC on Network shows up but I can no longer connect to it.
I have a Windows 7 desktop PC that's connected to my network. When I open File Explorer, I can see it on the network. Until a few weeks ago, I was always able to connect to it using Remote Desktop. Then all of a sudden, it stopped working. I have 2 Windows 11 laptops, both fairly new. I have another Windows 10 desktop on the network and I can not only connect via Remote Desktop, but I can also clck on it in File Explorer. I can't figure out what changed or how to fix it. Thank you in advance for any help you can provide. This is what I'm seeing in File Explorer. I can connect with no problems to DELL_NAS. I can't connect to DESKTOP-PC.
Taskbar goes dark black intermittently
Pretty sure this is a bug with Windows' MPO or graphical presentation model, but basically: For the past few months my taskbar has 'randomly' been going dark black, usually with Chrome open. Upon moving the mouse or clicking the taskbar, it immediately reverts. It's not a monitor and it's not a driver issue. This has also persisted across a fresh format and fresh driver installs. Turning off "Show shadows under windows" seems like it reduced the frequency, but it still happens even with that disabled. I've been told that potentially, disabling HAGS might fix it - but that shouldn't be necessary in the first place. What is going on with this?
