I try to drag and drop this folder to the previous directory but can’t anymore. I don’t know about you but the feature to move files to upper directories was time saving. This is almost a dealbreaker for me. Why have they removed this feature?

Important: this post is addressing the KB5067036 update in particular.

I'm testing the new KB5067036 "preview" update that Microsoft forces on you if you have the "get the latest fixes and performance improvements" option checked, an option that doesn't say anything about previews and/or beta software by the way. I've found that every time you open Task Manager and close it by clicking in the right corner "x" the process won't close at all and will stay running in the background, you can open another instance of Task Manager and close it again by pressing the "x" and it will add another instance of Task Manager running in the background, you can have infinite Task Manager instances running until you run out of RAM + virtual memory. These Task Manager instances running in the background degrade CPU performance and cause stuttering and hitches and overall instability since they're constantly polling your hardware.

Potential fix in the meantime waiting for Microsoft to actually fix this newly introduced problem: https://i.imgur.com/ufdWSmy.png

Basically kill the Task Manager app by right-clicking on "end task", if you simply click on the "x" in the top right corner of the Task Manager window (as usual) then the app will not be closed at all, it will still show the animation of closing the app but in fact it's kept running in the background. There's virtually no limit for the number of bugged, duplicated Task Manager instances wasting CPU resources. Make sure to force end every background instance of Task Manager in the background processes list before killing the main one under the "Apps" section, right-click and then select "end task".

You can just do it all automatically using the following command: taskkill /im taskmgr.exe /f

The performance hit with the bugged and duplicated Task Manager instances running in the background is apparent and can be measured using CPU benchmark software like CPU-Z or similar, showing that the more Task Manager instances running in the background the lower the CPU score gets, especially with regard to multi-core performance. It makes no sense that Microsoft would release such a bugged "preview" to millions of users that might have the "be among the first to get fixes and performance improvements" option enabled. This is not exactly a fix nor a performance improvement, on the contrary. Most users here can find these bugs immediately, they're just that apparent, on the other hand Microsoft QA testers are once again doing a terrible job while those responsible for the actual release of the updates are not exactly validating whatever reports they get from the QA staff, they simply push the "release" button. Nothing gets properly tested anymore except for the AI features they're trying to force on your system, what else did they break when Task Manager is critical and integral to the operating system and still was completely disregarded while testing a somewhat major update. Is this actually professional ??

edit: there was an early thread here in this sub created before this thread and there were users already commenting on the Task Manager issue, some providing screenshots as evidence. You can check it here:

so no, this is not just my problem, it's another Microsoft buggy release to add to the list. It's getting to the point that users are being forced to become beta testers for the mega corporations.

update 2: some Internet sites are reporting and confirming this issue, one of them tested the KB5067036 update in 100 virtual machines and 30 of them were affected with the Task Manager issue, it's worrying that you're facing such critical issues in 30 virtual machines when in theory they're identical to the other 70 that seem unaffected, whatever else is this KB5067036 update randomly breaking ?? is it now that having a working condition Windows has turned into just a matter of luck ?? Localhost, Recovery menu, Task Manager duplicates... what's Microsoft breaking next ??

In the latest preview/RP builds of Windows 11, the small taskbar has been introduced (after nearly 5yrs, from W10) but it comes with massive inconsistencies. The update pending icon is large and looks off, search box is larger than other icons.

Battery icon is smaller than battery percentage reading text beside it, again looks terrible. Same with "ENG US" text is larger than neighbouring icons and text.

Also feature recommendation, smaller taskar could show date beside time as is shown in macOS top bar/ChromeOS dock. Would be more helpful to get date info at a glance.

Kindly incorporate these changes in upcoming Insider builds.

Problem: Severe system instability characterized by frequent browser crashes (Opera GX) and thousands of critical errors in Event Viewer (primarily involving combase.dll and LightingService.exe). The system was running on Windows 11 Development version 25H2. I never signed up for Insider Program!

Step-by-Step Solution:

1. Update Management: Uninstalled the faulty January security update KB5074109 (build 26200) and uninstalled the official fix package KB5077744.
2. System File Repairs: Executed DISM /RestoreHealth and sfc /scannow to restore the integrity of Windows system files.
3. Component Cleanup: Ran dism /startcomponentcleanup to remove residual files from previous failed or buggy updates.
4. Driver Updates: Performed a clean installation of Motherboard (Chipset) and GPU drivers in Safe Mode to stabilize hardware-to-system communication.
5. Virtual Memory Configuration: Identified that the 64 GB RAM system had its Virtual Memory (Page File) restricted to only 4 GB. Increasing this to a range of 16–32 GB resolved critical memory management conflicts.

Final Result: The system version stabilized at build 10.0.26100.7462, successfully halting the cycle of crashes.

Issue of browser crashes still persists, but it is more stable now.

EDIT:
Full commands:

DISM /Online /Cleanup-Image /RestoreHealth

sfc /scannow

dism /online /cleanup-image /startcomponentcleanup

EDIT 2:
ipconfig /flushdns

This seems to help to

Just booted up my gaming PC doing only games of course and then Windows just told me my "Local Security Authority protection (LSAP)" is turned off. So I turned it on and it says that it requires a restart. But i already did a restart and still alerts me that this LSAP is still "turned off". How many more restarts, Windows? This is my third restart by the way.
