Every time I boot up in my laptop, I am getting a pop up telling it can't find a "killer app" application and advising me to look in the MS app store for the application. I've tried all the solutions suggested in a Google search and none work. There is no related app in my app listing to uninstall and I've tried all the rest of the solutions. Nothing works. What is going on and how do I get rid of this? This is in Windows 11.Solved35Views0likes1CommentCan't Sign in to anything with my Microsoft account
After the last update or so, I can't sign in to the Microsoft store or the Xbox app or the settings. There is no error code or anything, it just flashes the sign in page and disappear. In the store I get the error "We encountered an error. Please try signing in again later." and that's all. I tried all sorts of thing like resetting and repairing the Microsoft store and Xbox app, but those did nothing. i tried these commands "sfc /scannowsfc /scannow" and "Dism /Online /Cleanup-Image /RestoreHealth" but still nothing. Does anyone have the same error or knows a fix, please let me know. Thanks24Views0likes2CommentsSave the date: Windows Office Hours - January 15, 2026

I have been unable to launch any version of Minecraft Java since around the time when we had the Windows 11 issue that locked the keyboard upon startup and required a restart to unlock it. After trying multiple other fixes for Minecraft over the past few weeks, I finally did a complete reinstallation of Windows 11 hoping that would help, but it did not solve the problem. I’m posting a screenshot of the error message that I receive when I create a new installation in Minecraft Java and try to launch it. After I close the error message, if I try to launch it again, my computer completely freezes, and my keyboard locks up. I have to force shutdown using the power button. I would really appreciate any insights that anyone has!67Views0likes4CommentsWindows 11 24H2 background automatically switches to solid color
After upgrading to Windows 11 Version 24H2, the system desktop background frequently switches to solid colors (such as black or white) automatically. This issue is suspected to be related to installed third-party desktop or customization software, but the exact trigger remains unclear. Please provide troubleshooting steps and a solution.25Views0likes1CommentCannot make file association with a microsoft store app
Hello forum So the problem is that there is no way to set a specific file-app association with a microsoft store app (making a file opening with a certain software) because: 1) When trying to select application through "open with menu -> search in mircosoft store" when it selected it just opens app and nothing happens (as in video) 2) There is no exact install directory and even if you manage to find some hidden .exe file it doesn't work (tried that, as seen in video) https://www.youtube.com/watch?v=1QLqGYPUkZw27Views0likes1CommentFiles in the latest version of Windows 11 cannot be dragged to parent folders.
n a freshly installed Windows 11 system (latest version), attempting to move files to their parent folder via drag-and-drop fails (no response or ineffective), whereas this operation worked normally in previous system versions. It is suspected that this functionality was removed or restricted after the system update. Seeking confirmation and a solution.28Views0likes2CommentsWindows 11 that causes severe eye strain and headaches
Hello, I am reporting a serious display-related issue in Windows 11 that causes severe eye strain and headaches and makes the OS unusable for me and a few other people. We migrated the entire company, 300 people, from Windows 10 to Windows 11 due to security requirements, but now about 30 employees are suffering from headaches. Since switching from Windows 10 to Windows 11, I experience strong headaches and visual discomfort even during short sessions and even when simply looking at the desktop with no active workload. This issue is consistent and reproducible. Based on extensive testing, I suspect Windows 11 applies forced temporal dithering or other frame-to-frame color modulation at the OS / DWM / graphics pipeline level, even when using a native 8-bit display. System configuration: Native 8-bit IPS monitor (not 6-bit + FRC) NVIDIA GPU HDR fully disabled (Windows, driver, and monitor) Tested via DisplayPort and HDMI Multiple refresh rates and timings tested Troubleshooting steps already performed: Clean installation of multiple NVIDIA drivers (Game Ready and Studio, DDU used) Explicitly set 8 bpc color depth Tested RGB and YCbCr output formats Disabled G-SYNC / VRR at both driver and monitor levels Disabled MPO (Multiplane Overlay) via registry Reset NVIDIA Control Panel to defaults Removed all custom ICC profiles and reverted to default sRGB Disabled Night Light, blue light filters, and all adaptive color features Tested different brightness levels and fully disabled monitor post-processing Tested multiple scaling settings (100–150%) Tested different resolutions and timing standards (CVT / CVT-RB) Tested output via integrated GPU (where available) Key observation: With the exact same hardware, cables, monitor, and settings, Windows 10 does not cause these symptoms. The problem appears only on Windows 11, which strongly suggests a change in the Windows 11 graphics pipeline, DWM behavior, or color management. This is not a subjective preference issue but a health-related problem. Questions: Is there any supported or undocumented way to fully disable THIS in Windows 11? If not, then are there plans to provide explicit user control over color modulation in future Windows versions, given that this behavior causes severe eye strain and headaches for some users? I would appreciate a response from a technical specialist familiar with Windows graphics, DWM, and display output behavior.125Views2likes4CommentsKeeps switching to "light" mode at 7:40am daily
I have Windows 11 25h2 on my HP laptop purchased in November 2024. Ever since I bought it, the display mode changes daily at 7:40am (PST) exactly to light mode. I try to keep all things in dark mode due to light sensitivities. Having my computer suddenly turn bright can by migraine inducing! I even keep my settings open to change it back to dark as quickly as possible but that is getting really old after a year+. This should not be happening. I have never had a computer do this! My last laptop (also HP) didn't have this issue This what it looked like at 7:40am This what it was at 7:39am and after I switched it back Any help would be greatly appreciated!27Views0likes1CommentWhy is my Win 11 slower than Win 10?
When I upgraded from Win 10 to Win 11 on my laptop, I noticed a significant decrease in performance. Tasks that used to be swift now take noticeably longer, and overall system responsiveness has decreased. From boot times to opening applications and navigating the interface. Despite my laptop meeting the system requirements for Win11, the transition has resulted in a frustrating experience where productivity is hampered by sluggish performance. I'm seeking assistance to understand and potentially resolve this issue.16KViews5likes14Comments
