How can I display or view Android screen on PC via wifi or usb?
Hi everyone, I want to display and view my Android phone screen directly on my PC (Windows 11), but I'm not sure what the best method is. I’d like to see my phone screen on my computer monitor, ideally with low latency and decent quality. Here’s what I’m looking for: USB or wireless? Open to both, but reliability is more important than convenience. Purpose: Mostly for app demos, some light gaming, and occasionally watching media from my phone. Controls: I don't necessarily need to control my phone from the PC. Just viewing the screen is fine, though mouse/keyboard support would be a bonus. Phone: Google Pixel 9A with Android OS 16 Does anyone have recommendations viewing Android phone screen on PC? Also, any tips on reducing lag or improving quality would be great.
Surface is getting very hot very quickly and I have no idea why
This has been a problem for a couple of weeks now and I don't know why... while it's not giving overheating errors or anything like that, I use it for drawing a lot, and the touchscreen becomes unbearable to use very quickly, usually within a half hour. There are also times when I'm using it normally (scrolling the internet, discord, spotify, etc.) and happen to touch the screen and it's very hot to the touch. Possibly unrelated, but I've also noticed it restarting much more frequently; where I previously noticed that I could close my surface and open it again the next day to have my apps still open where I'd left off, lately I feel like it's been closing everything more often. (Lots of my art program opening restored files, lots of "Chrome didn't shut down correctly," all that good stuff.) My initial thought was that I have some background processes that are overloading my computer, however nothing is particularly new save for the Adobe Creative Cloud, which I recently installed for school. I can't delete it, but did stop it from starting upon turning my computer on just in case. When looking at my task manager, my memory seems very high (85% - 90%), but I don't know if that would cause overheating, or if that's even considered high. Beyond that, I don't know why it would even be high, considering I'm not doing anything I don't do normally. I am not well versed in computers, and I recognize that I might be missing something altogether. I've attached a screenshot of my task manager just in case someone has insight that I don't.Windows 11でiPhoneの画面をPCにミラーリングする方法を教えてください

Did ovulation likely happen or should I expect it soon?
So I've never caught my surge doing this before but I don't normally keep testing every couple of hours like I am this cycle. My LH started to surge with my ratio on Premom going to 0.88 (11:33am), then it dipped to 0.59 (5:52pm) even though my urine was extremely concentrated and darker than the previous test, then I was hydrated better and it rose to about 1.00 (9:36pm). I had some cramping this morning and throughout the afternoon until around 9pm. Should I assume I already ovulated or do you think I'm ovulating soon? Does anyone else here experience this weird roller coaster pattern during your LH surge? I'm wondering if we missed the window or not and previously I never caught my LH going up then down and back up again. Thank you in advance for any shared experiences and information!
Windows 11 25H2 SMB Client Directory Cache Regression
- QUERY_DIRECTORY Increased 95x, "dir" ETW Events Dropped to Zero - Hi SMB Team, I've identified a significant performance regression in the SMB client on Windows 11 25H2 affecting network file share operations. I have comprehensive data from a controlled comparison between clean installations of 23H2 and 25H2. Environment - Two clean-installed PCs (23H2 vs 25H2) connected to the same file server on the same network - Application: Python-based tool loading .py files from SMB file shares - Both PCs have identical SMB client configuration defaults for all cache-related parameters Measured Impact | Metric | 23H2 | 25H2 | Ratio | |--------|------|------|-------| | Application startup time | 26 sec | 80 sec | 3.1x slower | | Total SMB2 packets | 12,544 | 227,796 | 18.2x | | QUERY_DIRECTORY packets | 1,128 | 107,382 | 95.2x | | READ packets | 586 | 570 | ~1.0x (identical workload) | | PerfMon Metadata Requests/sec (avg) | 87.10 | 1,185.52 | 13.6x | The READ count is virtually identical (586 vs 570), confirming the actual workload is the same. The 25H2 client is issuing 95x more directory enumeration requests to the server for the same set of files. Root Cause: ETW "dir" Cache Events Dropped to Zero I captured ETW traces from the Microsoft-Windows-SMBClient provider on both systems and extracted cache-related events. This is the definitive finding: | ETW Event Type | 23H2 | 25H2 | |----------------|------|------| | file | 151,667 | 185,365 | | dir | 93,917 | 0 | | performance | 0 | 106,557 | On 23H2, the SMB client generated 93,917 "dir" events, indicating active directory cache usage. On 25H2, this event type is completely absent — zero occurrences. A new "performance" event type (106,557 occurrences) appears in 25H2 but does not serve as a cache mechanism. This indicates that the directory cache code path in the SMB client driver has been removed or disabled in 25H2. SMB2 Command Breakdown (Wire shark) | SMB2 Command | ID | 23H2 | 25H2 | Ratio | |--------------|----|------|------|-------| | CREATE | 5 | 3,278 | 56,536 | 17.2x | | CLOSE | 6 | 2,274 | 54,462 | 24.0x | | READ | 8 | 586 | 570 | 0.97x | | QUERY_DIRECTORY | 14 | 1,128 | 107,382 | 95.2x | | QUERY_INFO | 16 | 4,284 | 8,846 | 2.1x | | IOCTL | 11 | 10 | 0 | — | | CHANGE_NOTIFY | 15 | 0 | 0 | — | | Total | | 12,544 | 227,796 | 18.2x | 99.7% of all 25H2 SMB2 traffic is file discovery overhead. Only 0.25% is actual data reads. Additional Verification: Minimized Search Path (25H2) I also tested a minimized configuration on 25H2 using explicit path specification to reduce directory traversal: | Pattern | Startup | Total Packets | QUERY_DIRECTORY | |---------|---------|---------------|------------------| | 23H2 default | 26 sec | 12,544 | 1,128 | | 25H2 minimized paths | 30 sec | 119,153 | 57,888 | | 25H2 default | 80 sec | 227,796 | 107,382 | Even with minimized search paths, 25H2 generates 9.5x more packets than 23H2 and the ETW "dir" events remain at zero. This confirms the issue is in the OS driver, not the application. SMB Client Configuration (Identical Defaults) All cache-related parameters are identical between 23H2 and 25H2 at clean install: - DirectoryCacheLifetime: 10 (both) - DirectoryCacheEntriesMax: 16 (both) - FileInfoCacheLifetime: 10 (both) - FileInfoCacheEntriesMax: 64 (both) - FileNotFoundCacheLifetime: 5 (both) - FileNotFoundCacheEntriesMax: 128 (both) I also tested increasing all cache parameters significantly (DirectoryCacheLifetime=60, FileInfoCacheEntriesMax=65536, etc.) with no improvement. Additionally, setting RequireSecuritySignature=False (changed to True by default in 25H2) had no effect. Affected Driver Versions | Driver | 23H2 | 25H2 | Size Change | |--------|------|------|-------------| | mrxsmb.sys | 10.0.22621.6133 (685 KB) | 10.0.26100.8246 (931 KB) | +35.9% | | mrxsmb20.sys | 10.0.22621.6133 (333 KB) | 10.0.26100.8115 (390 KB) | +17.2% | | rdbss.sys | 10.0.22621.6133 (505 KB) | 10.0.26100.8115 (562 KB) | +11.4% | The 35.9% size increase in mrxsmb.sys suggests substantial implementation changes beyond routine patches. Questions 1. Is the removal of directory cache events ("dir") in 25H2 an intentional design change or a regression? 2. If intentional, what is the recommended mitigation for applications that perform heavy directory enumeration over SMB? 3. Is there a hotfix or upcoming update that addresses this behavior? Thank you for your time.Battery stuck at 44% after Windows update (HP laptop)
My HP laptop battery is stuck at 44% even when plugged in for over an hour. It shows charging, but the percentage doesn’t increase. When unplugged, the battery drains normally. This started after a recent Windows update. I’ve already tried restarting, reinstalling battery drivers, power reset, and checking BIOS settings, but nothing worked. Any solution for this?Comment effacer un disque dur avant de vendre son PC sous Windows 11/10 ?

Windows Defender Notifications Not Working — Even After Clean Installs, BIOS Reset & Full Repairs
Hi everyone, I’m facing a strange and persistent issue with Windows Defender notifications, and I’m hoping someone here may have encountered something similar. During routine system maintenance, I noticed that Windows Defender has completely stopped showing notifications — no scan completion alerts, no threat‑found pop‑ups, nothing at all. Troubleshooting I’ve Already Done To rule out corruption, configuration issues, or hardware‑related causes, I’ve carried out extensive testing across multiple clean installations: Reinstalled Windows using the Media Creation Tool → still no Defender notifications Reinstalled Windows again using Rufus → same result Reset BIOS / cleared CMOS Installed an older Windows 11 build (offline, before updates) → still no notifications Deleted all partitions on every reinstall (full clean install) Verified all Windows Defender notification settings, including Enhanced Notifications Checked Windows notification settings to ensure Windows Security is allowed Ran SFC Performed DISM /Online /Cleanup-Image /RestoreHealth Confirmed no registry or Group Policy entries suppressing notifications Reinstalled Windows Defender components Scanned with third‑party tools and Microsoft MRT — no issues found Ensured Windows Push Notification System Service is running Despite all of this, Defender notifications never appear on any fresh installation. Microsoft Support I opened a support ticket with Microsoft. One engineer performed an in‑place repair install Another advised me to post the issue here for deeper investigation Ticket reference: 710148747 Additional Technical Findings 1. Notifications are not being suppressed No GPOs applied No Intune configuration profiles No registry entries modifying notification behaviour Local notification settings fully enabled Defender notifications fully enabled It’s not a profile corruption It’s not a user hive issue It’s not a local DB issue It’s OS‑level 2. Windows Notification Platform (WNP) appears to be the root cause Across multiple clean installs: ShellExperienceHost exists on disk. Focus Assist toggle produces no toast (not sure it does) other apps like mail, Logitech, steam can toast notification, i don't see defender toasting any scan notification. WNP is partially working Defender is partially registering The scan‑completion channel is failing specifically This behaviour is consistent and reproducible. 3. Defender functionality validated using EICAR I manually created the EICAR test file and ran a scan: Defender detects and removes the file correctly Detection appears in Protection History A threat notification appears Scan completion notifications do NOT appear This confirms: Defender itself is functioning The notification delivery layer (WNP) is not working question at MS QA- https://learn.microsoft.com/en-us/answers/questions/5864084/windows-defender-notifications-not-working-even-afHow to find out what's taking up space on a C drive in windows 11?
My Windows 11 laptop is showing that the C drive is almost full, but I have no idea what is actually taking up all the space. I don’t store many large files like videos or games, so I’m confused about where the storage went. I checked "This PC" and saw the used space bar, but that doesn't tell me which folders or files are using the most storage. Is there a built-in tool in Windows 11 that can easily find out what's taking up space on a C drive? Or do I need to use third-party software? I'm not very experienced with advanced system settings, so simple steps would be really helpful.
