Power Apps - development vs production
“It works fine in development.” Probably one of the most dangerous sentences in application development. 😄 I've seen Power Apps behave perfectly when we test with a small amount of data. Then the application goes to UAT or production and suddenly users start reporting: “It's taking too long to load.” “The gallery is empty.” “The search isn't returning everything.” “Why is this screen so slow?” Many times, the formula itself isn't the only issue. The data is. For example, an app might work perfectly with a few hundred SharePoint records. But as the list grows, the same approach can become a problem because of delegation and the amount of data being processed. That's why I've started asking these questions before finalizing an app: Is this query delegable? How much data will this list have after one year? Are we loading records into collections unnecessarily? Are we doing multiple LookUps inside a gallery? Can the filtering happen closer to the data source? Would Dataverse be a better option for this requirement? These questions don't always come up when we're building the first version of the application. But they become very important later. One thing I'm learning with Power Platform is that a solution that works today is not necessarily a solution that will scale tomorrow. Sometimes spending a little more time on the data and architecture in the beginning saves a lot of time later. Curious to know what others have experienced: What was the biggest Power Apps performance issue you faced after moving an application to production?
Reclamo técnico — Windows Update / Fallo crítico de arranque / Activación
Reclamo técnico — Windows Update / Fallo crítico de arranque / Activación El 28/08/2026, luego de una actualización de Windows 11, mi instalación dejó de iniciar correctamente. La actualización involucrada es KB5120998, correspondiente a Windows 11 25H2 / OS Build 26200.9278, publicada por Microsoft el 27/08/2026. El sistema pasó de funcionar normalmente a presentar durante el arranque: DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS y posteriormente: STOP 0xC000021A STATUS_SYSTEM_PROCESS_TERMINATED El fallo persistió incluso intentando iniciar mediante Safe Mode (F4) y Safe Mode with Networking (F5), por lo que no se trataba de un problema de una aplicación o proceso de inicio del usuario. Se realizó un proceso completo de recuperación utilizando Windows Recovery Environment (WinRE) y reparación offline de la instalación. Durante el diagnóstico se identificaron problemas en el Component-Based Servicing (CBS) / Component Store. Los intentos de reparación con DISM no pudieron completarse correctamente y se obtuvo: 0x800F0915 CBS_E_REPAIR_CONTENT_MISSING Entre los componentes involucrados se identificó: wow64_microsoft-windows-errorreportingcore 10.0.26100.9278 También fue necesario intervenir sobre la configuración de arranque UEFI/EFI para intentar recuperar el sistema. La recuperación de la instalación original finalmente no fue posible, por lo que, después de agotar los procedimientos de reparación, fue necesario formatear y reinstalar Windows. La reinstalación tuvo que realizarse dos veces, ya que la primera instalación presentó problemas al intentar recuperar la configuración/cuenta anterior. Por lo tanto, el incidente produjo la siguiente cadena: KB5120998 ↓ Windows 11 25H2 / Build 26200.9278 ↓ Fallo durante el arranque ↓ DRIVER_UNLOADED_WITHOUT_CANCELLING_PENDING_OPERATIONS ↓ 0xC000021A ↓ Safe Mode también falla ↓ WinRE / reparación offline ↓ CBS / Component Store: 0x800F0915 ↓ Recuperación UEFI/EFI ↓ Imposibilidad de recuperar la instalación ↓ Formateo ↓ Dos reinstalaciones de Windows Actualmente existe además un segundo problema: la licencia original que estaba funcionando en este mismo equipo ya no es validada después de la reinstalación. Windows devuelve: 0x803FA067 También intenté utilizar el mecanismo de activación mediante Installation ID, pero el sistema/web de activación de Microsoft tampoco reconoce correctamente dicho identificador.Windows Security shows warning icon on startup – but everything's green when I open it
For the past two weeks, I've been seeing something odd with Windows Security. Right after I start my PC, the icon in the taskbar shows a yellow warning symbol, like there's something that needs my attention. But when I open it, everything is green—no actions required. If I just leave it alone, the warning disappears on its own after about a minute and turns back into the normal green checkmark. I'm only using Windows Defender, no third-party antivirus. Anyone else experiencing this? Win 11 Pro, 25H2 – Build 26200.9168.
Win11 Laptop enters Connected Standby instead of Sleep when closing the lid
When you close the laptop lid, the device enters a networked standby state rather than the traditional sleep state, which means the battery continues to drain even when the device is idle. The device is not completely shut down, and network traffic may remain active during standby. Setting the power button to sleep mode does not change this behavior. You can verify this by running the powercfg /a command; the system supports standby mode but does not support the traditional S3 sleep mode.
The Windows 11 search bar isn't working; the cursor keeps refreshing every second.
I'm using a new Windows ARM laptop, the Samsung Galaxy Book 4 Edge, and it suddenly started acting up. The taskbar won't open, and the cursor is refreshing every second, as if it's constantly reloading. This issue started after a restart and still hasn't been resolved. I've installed all available updates, restarted File Explorer via Task Manager, and even tried ending the Search process. None of these steps have helped.Win11 Fonts installed manually disappear from the Fonts list after a system restart
When you manually install a font file using the Install option in File Explorer or the Install for All Users option, the font appears in the Fonts folder but disappears from the application's font selection list after a restart. Although the .ttf or .otf files remain in the Fonts folder, these fonts will no longer be selectable in applications unless you reinstall them. Reinstalling the fonts after each startup provides a temporary solution to this issue.PC keeps crashing and restarting – black screen then login screen
Hey everyone, I could really use some help here. I'm still pretty new to this stuff—I know my way around a restart and that's about it, honestly. Recently my PC has been crashing randomly. Out of nowhere, the screen goes black, and a few seconds later I'm back at the login screen. This happens even when I'm in the middle of a game. I actually ran into this issue before and ended up resetting the whole system because I couldn't figure it out. Last time I spent over a day trying to run an sfc /scannow check and it took forever. Now it's happening again, so I'm hoping someone can help me figure out what's going on. I've attached a screenshot of the problem reports—any idea what type of error this is or what I should try next? Appreciate any advice. Thanks for reading.New B650 AORUS ELITE AX Motherboard for Windows 11 Does Not Support Wi-Fi
I just finished building my first computer. I installed Windows 11 and used a USB drive to install all the drivers needed for the B650 AORUS ELITE AX motherboard. I thought everything was set. But there are still absolutely no wireless network options. Neither the Wi-Fi adapter nor any other related options are showing up. This problem has been plaguing me for a week, and I’m at a loss. Does anyone know what I might have overlooked?
Can I upgrade my Windows 11 license from home to pro without reinstalling?
I have an ASUS tower PC about 2 years old. I have been happily running Windows 10 Pro from a license I owned previously. Now that Windows 10 is no longer supported, Microsoft has "upgraded" me to Windows 11 Pro, overwriting Win 10, but is unlicensed and so limits my Win 11 functionality. For example- I can't change many of the Windows settings. I am blind and need to change a number of settings just to use my computer. My desktop is constantly prompting me to provide a Win 11 Pro license key. I tried using the Win 10 Pro license key but that didn't work. I tried installing Win 10 and 11 dual boot, but my PC doesn't allow dual boot. The ASUS PC includes a license of Windows 11 Home, but I can't use it with the installed Windows 11 Pro. I could install Win 11 Home, but that would start from scratch and lose some of my local data and put my settings back to default, which in my case would be ausability nightmare. The easy way out is to just get a new license for Win 11 Pro. Then Windows and the settings would just stay the way they are, and enable all of my apps,data and settings. To keep this from getting too expensive, can I buy an upgrade license from Win 11 Home to Pro? If so, can I use it without reinstalling Windows 11? If that doesn't work, can I downgrade my installation of Win 11 Pro to Win 11 Home without reinstalling? If neither of the above is possible, I’ll have to just buy a new license of Windows 11 Pro. Where do I get that? Are there any options to keep the cost down to that of an upgrade rather than a net new license?
