KB5121003 breaks AMD X470 USB xHCI: DRIVER_POWER_STATE_FAILURE 0x9F
I am reporting what appears to be a USB/xHCI regression immediately following installation of the August 11, 2026 cumulative update KB5121003 on Windows 11 25H2. System information - OS: Windows 11 25H2 - Build after update: 26200.9168 - Update: KB5121003 - Motherboard: ASUS ROG STRIX X470-F GAMING - Chipset: AMD X470 - CPU: AMD Ryzen 7 5800X 8-Core Processor - Affected xHCI controller PCI instance: "PCI\VEN_1022&DEV_43D0&SUBSYS_11421B21&REV_01\4&2c18e2e3&0&000B" - Associated USB Root Hub instance: "USB\ROOT_HUB30\5&4964544&0&0" - Windows USB driver stack involved: "USBXHCI → ACPI → USBHUB3" All affected USB devices were working normally immediately before installation of KB5121003. During installation, the first reboot completed normally. Windows then requested a second scheduled reboot through TrustedInstaller as part of the update servicing process. Relevant System event log timeline - Approximately 20:59 – first update restart initiated. - Approximately 21:00 – first shutdown and subsequent boot completed. - 21:01:19 – "TrustedInstaller.exe" requested another scheduled restart, reason: Operating System Update. - 21:01:28 – Windows shut down for the second update reboot. - Approximately 21:01–21:06 – the system remained without video output for approximately five minutes. - Approximately 21:06:58 – Windows started again. - 21:07:03 – "WER-SystemErrorReporting", Event ID 1001, recorded a bugcheck occurring during the preceding boot/update phase. The bugcheck was: DRIVER_POWER_STATE_FAILURE (0x9F) Parameters: "0x0000009f (0x3, 0xffff91076083edc0, 0xffffba0875fcf640, 0xffff9107601ab560)" Minidump: "C:\Windows\Minidump\081226-4968-01.dmp" Analysis of the minidump shows that the Physical Device Object identified by bugcheck Arg2 belongs to the USB xHCI device stack. The affected PCI device is: "PCI\VEN_1022&DEV_43D0&SUBSYS_11421B21&REV_01\4&2c18e2e3&0&000B" The reconstructed device stack is: "USBXHCI → ACPI → USBHUB3" The associated Root Hub instance is: "USB\ROOT_HUB30\5&4964544&0&0" The blocked IRP referenced by Arg4 is a power IRP: "IRP_MJ_POWER / IRP_MN_SET_POWER" The active device object belongs to: "\Driver\USBHUB3" and the Physical Device Object involved belongs to: "\Driver\USBXHCI" This indicates a timeout in the USB xHCI / USB Root Hub power-state transition during the second servicing reboot. After Windows subsequently booted successfully into build 26200.9168, the affected USB Root Hub/controller remained in an error state in Device Manager. All USB peripherals connected through the affected USB path became unavailable to Windows. This includes devices of different types that had all been working normally immediately before the update, including: - USB keyboard - USB audio interface - USB webcam - other USB-connected peripherals on the affected controller/Root Hub The failure is therefore not limited to a particular peripheral, application, or third-party device driver. Multiple unrelated USB devices became unavailable simultaneously because the common upstream USB controller/Root Hub failed to initialize correctly. The USB failure appeared during the reboot sequence that applied KB5121003, and the affected Root Hub has remained non-functional since that update. The temporal relationship with KB5121003 is therefore very strong, while the crash dump independently identifies the failing subsystem as the Windows USB xHCI/USBHUB3 stack on the AMD X470 platform. I have retained both: - the complete System EVTX log covering the update and reboot sequence; - the minidump "081226-4968-01.dmp" containing the 0x9F crash and affected USB device stack. Both files are available for engineering analysis. Please investigate a possible regression in USB xHCI / USBHUB3 power-state handling introduced by KB5121003 / build 26200.9168, particularly on AMD X470 / PCI "VEN_1022&DEV_43D0" configurations.
Is it normal for Windows to give an error with a new product key but still upgrade?
I tried to upgrade my new clean installed Windows 11 Home laptop to Windows 11 Education using a key that I got from Microsoft Azure for students (I already used this key once before on this laptop, but I clean installed it right now, so I'm using this key again on that same laptop). I entered the new key and it seemed to be working (it said installing upgrades) and when it got to 100% downloaded, it gave an error saying "We can't upgrade your edition of windows." So then I tried entering the product key again 2 more times, but then each time it gave another error saying "the product key you entered didn't work." So then I restarted my computer to hopefully fix the errors, but when I restarted, it got the regular black screen for updages, and it also said "adding features," so then it updated like that for only about a minute, and then booted up to normal Windows. I opened settings and it showed that Windows 11 Education was activated (with digital license to microsoft account). So then I entered the same product key one more time, and it said this copy of Windows has been successfully activated (even though it already was activated with Windows 11 Education after I restarted, which I don't know why it happened in the first place considering it gave an error?). It seems like all of the Education features are available though (like hyper-v and group policy). But why did this happen? Is Windows 11 Education successfully installed, or is it possible for it to be corrupted? What should I do? Any help would be greatly appreciated. Thank you!
Windows 11, Start button menu, make it show all apps by default
I upgraded to Windows 11 this week and I don't like the new Start button menu. I don't want "pinned" apps. I want to see All Apps in a list like before. Why don't we get the option to choose how we want things to look? So frustrating. Barbara
Why is everyone hating on Windows 11?
I’m genuinely curious why Windows 11 seems to get so much hate in some communities. I understand some of the common criticisms, such as Copilot, Microsoft account requirements, preinstalled apps, telemetry, and the new context menu. But from my perspective, many of these things can be worked around or customized. For example, you can bypass the account setup, remove unnecessary software, use local accounts, and tweak parts of the UI. That’s why I’m wondering: is the dislike mainly about Microsoft’s direction and defaults, or are there deeper technical or usability issues I’m missing? For context, I use different devices: a ThinkPad, a MacBook, and a windows gaming PC. I’ve been using Windows since XP, and even though I like macOS a lot, I sometimes miss the Windows experience. Maybe it’s partly nostalgia. I’m not trying to start a Mac vs. Windows debate. I’m just interested in understanding the perspective of people who strongly dislike Windows 11. What are your main reasons?
Windows + D aka go to desktop shortcut.
It works like a charm on 1 screen, but it's slightly annoying that when i press that combination everything on every screen goes away... make possibility to remove screens from some actions. My second screen is only for chat and stuff uknow so all of the things should be there always :) Wouldnt mind if i could lock those in place too lol maybe in linux i can?
Remote access to asleep computer
Can a computer in sleep mode be remotely accessed? I had a problem with unauthorized access to my computer with access to my financial companies, resulting to attempted fund wires and the accounts being locked. Hopefully the computer is clean; anti-virus programs have been run, and browser caches cleared. In case the malicious software still is on the computer is it possible to remotely access it when it is in sleep mode?
