Thumbnails in Explorer.exe Using Up Significant Memory
It seems that there is an issue with explorer with storing thumbnail cache for folders containing 6k to 8k resolution videos. For context, I keep virtual reality videos in one folder and every single time I open this folder and browse through all other files and sub folders, the memory usage for explorer spikes up. I need help on how to fix this issue. Any workarounds such as storing thumbnail cache on the drive instead of the RAM would help. I'm using Windows 10 22H2
File History problems after installing KB5124008, KB5126052,KB5126146, KB5122878, and KB890830
This morning, I ran Windows Update on two Windows 10/11 computers, but the file history feature stopped working completely after the update. Previously, after updating KB5120249 and KB5101684, files could still be backed up to the D: drive normally. The "Last Backup" time in "File History" is not updating correctly. Newly created or saved Word documents, pictures, videos, etc., still show "No previous version available" in "Content → Previous Versions". No folders were corrected; their dates are automatically updated. After running Windows Update again today, the file history feature stopped working on both computers. The File History panel pops up but cannot be used, prompting for a hard drive connection. (The hard drive is connected and I've confirmed it can read and write.) resulting in an "InconsistentState" entry in C:\Users\User\AppData\Local\Microsoft\Windows\FileHistory\Configuration. I'm very angry. If Microsoft doesn't address this, I'll keep complaining. If anyone else has encountered the same situation, please leave a comment below. You can also check Microsoft Q&A or the Microsoft Community Hub. The five updates installed are: September 8, 2026—KB5122878 (OS Builds 19045.7725 and 19044.7725) September 8, 2026-KB5126146 Cumulative Update for .NET Framework 3.5, 4.8 and 4.8.1 for Windows 10 Version 22H2 2026-09 Security Update (KB5124008) (26200.9445) 2026-09 .NET Framework Security Update (KB5126052) Windows Malicious Software Removal Tool x64 - v5.145 (KB890830) Deleting the %LocalAppData%\Microsoft\Windows\FileHistory folder also failed. Furthermore, "File History" itself is not listed in Microsoft's "Deprecated Features List." While other backup features suggest that Microsoft has no plans to discontinue it. Microsoft is going to pretend it doesn't exist. These worked normally before the update but stopped working afterward. This is to inform other users experiencing the same problem.There is problem with file history logging after the recent Windows updates (KB5101684 / KB5121003)
Hi everyone, This is not spam, I did not spam the site. It appeared after the update. I hope Microsoft can resolve this issue, and I also hope other users experiencing the same problem can reply to me. Please, please. Ever since the latest Windows updates (specifically around KB5101684 / KB5120249 on Windows 11 Build 26200/Windows 10 Build 19045), The File History feature is almost unusable for me; although it works, the problem only occurs after an update. Symptoms: The "Last Backup" time in File History is not updating correctly. Newly created or saved Word documents, images, videos, etc., still show "No previous version available" in "Content → Previous Versions". The Correct folder's date is automatically changed. System details: OS: Windows 11 25H2 (Build 26200.9278) OS: Windows 10 22H2 (Build 19045.7663) Recent Updates Installed: KB5120998, KB5120249, KB5101684. Has anyone else experienced this issue with recent Windows updates? Currently, the only solution is to go to Control Panel → All Console Items → File History → Select Drive → Select D: drive again. After completing this step, File History will return to normal. This is a post I made. Other users who have experienced the same thing left comments below.

Hi everyone, I am writing to report a major regression bug with File History that was introduced in the recent Windows updates. This is happening across two entirely different machines with no settings changed, no system files modified, and no registry tweaks applied. The Issue: Windows 11 25H2 > after installing KB5101684 (July 29, 2026) Windows 10 22H2 > after installing KB5120249 (August 12, 2026) On both PCs backing up to a local drive (D:), the underlying files are actually being written to the drive, but the File History interface is completely broken: TheLast Backup time stamp in Control Panel frozen and fails to update automatically. In File Explorer, right-clicking new files > Properties> Previous Versions shows There are no previous versions available, making daily time-travel restoration impossible. Temporary Workaround: The only way to force it to sync is to go to Control Panel > File History > Select Drive, and re-select the D: drive again. This proves the backup engine works, but the automatic scheduling and catalog syncing are completely frozen by these updates. Please Help Upvote on Feedback Hub: I have already submitted this issue via the Feedback Hub but have received no official response yet. Since File History is critical for users who prefer local offline backups over OneDrive, we need to bring this to Microsoft’s attention immediately so they can patch it in the next cumulative update.

This past month has been very frustrating for me. It's not that I like to ramble, but I've genuinely encountered problems after updating. I want to ask Microsoft: after updating my laptop and desktop to KB5101684 and KB5120249, I'm experiencing issues with file history: Files can still be backed up to the D drive normally. The "Last Backup" time in "File History" is not updating correctly. Newly created or saved Word documents, images, videos, etc., still show "No previous version available" in "Content → Previous Versions". I haven't modified some folders; please change the modification dates yourself. Both updates state, "This update fixes an issue that affects File History automatic backups to network shares using Server Message Block (SMB). Backups did not work because Windows showed a false 'invalid credentials' error when connecting to SMB shares." I didn't expect the update to cause this problem; dozens of users have reported the same issue. Microsoft, please investigate and fix this. When will it be fixed? If you have the same problem as me, please leave a comment below. I want to ask Microsoft, why are there abnormal in the file history logs after these two updates? | Microsoft Community Hub According to methods suggested by online users: Open File Explorer, navigate to C:\Users\[Your Username]\AppData\Local\Microsoft\Windows\FileHistory, and delete all contents in the Configuration folder. Next, go to Settings > System > Storage, turn off File History, and then re-add drive D as the backup destination. This method still did not work.

Microsoft Print to PDF not working/missing.
The Microsoft Print to PDF was not working on my PC so I tried reenabling it via Windows Features in Optional Features and it won't turn back on. It gives error code: 0x800f0922. I also tried other various methods online and none work. All end with various error codes which all result in the service not working/turning on. I even filed feedback about 2 weeks ago with no response yet. I contacted support, where I was recommended to perform a repair via ISO but was then canceled by the agent as I am on an Insider build. I am on build 26300.8687. This is a summary of my diagnostic from Gemini which I had used to try to solve my issue. Here is a summary of the diagnostic, tracking every command I executed in PowerShell and the specific roadblocks the Windows subsystem threw back. The Add-Printer Layer attempted to use modern PowerShell commands to register the printer onto both the interactive prompt port and the standard local file port. Commands Ran: PowerShell Add-Printer -Name "Microsoft Print to PDF" -DriverName "Microsoft Print to PDF" -PortName "PORTPROMPT:" Add-Printer -Name "Microsoft Print to PDF" -DriverName "Microsoft Print to PDF" -PortName "FILE:" * **Errors Faced:** * `ObjectNotFound: (MSFT_Printer:ROOT/StandardCimv2/MSFT_Printer)` * `HRESULT 0x80070002,Add-Printer` --- ## 2. The Legacy PrintUI Layer To bypass the modern PowerShell cmdlet, I tried using the legacy Windows user interface print engine via standard command prompt syntax and escaped quotes. * **Commands Ran:** ```powershell cmd /c "rundll32 printui.dll,PrintUIEntry /if /b `"Microsoft Print to PDF`" /r `"PORTPROMPT:`" /m `"Microsoft Print to PDF`"" rundll32 printui.dll,PrintUIEntry /if /b "Microsoft Print to PDF" /f "C:\Windows\System32\spool\DRIVERS\x64\3\prnms009.inf" /r "PORTPROMPT:" /m "Microsoft Print to PDF" Errors Faced: A graphical dialog box error: Operation could not be completed (error 0x00000002). The system cannot find the file specified. The Deployment Script Layer (WMI/CScript) I tried deploying the printer using Windows’ built-in visual basic administrative scripts to side-step the user interface layer completely. Command Ran: PowerShell cscript $env:windir\System32\Printing_Admin_Scripts\en-US\prnmngr.vbs -a -p "Microsoft Print to PDF" -m "Microsoft Print to PDF" -r "PORTPROMPT:" * **Errors Faced:** * `Unable to add printer Microsoft Print to PDF Error 0x80041002 Not found` * `Operation PutInstance` * `Provider Win32 Provider` * `Description The system cannot find the file specified. Win32 error code 2` Ultimately, every single command failed with an identical variation of **"File Not Found" (Error 2 / 0x80070002 / 0x80041002)**.
MSIX package and shortcut icons
I see some strange behavior and can't explain why it is not working. I am playing around with the MSIX package and shortcut icons. I created them using the Visual Asset generator (https://apps.microsoft.com/detail/9mz6qrqtdkf2?hl=en-US&gl=US) and copied them to the Assets folder. When configuring the shortcuts with the files, the shortcuts and package logo stays blank. When I open the manifest and point the entries hardcoded to the files the icons appear. Like this config below. <Application Id="PSFLAUNCHERTwo" Executable="PsfLauncher2.exe" EntryPoint="Windows.FullTrustApplication"> <uap3:VisualElements AppListEntry="default" BackgroundColor="transparent" Description="Fair Prod" DisplayName="Fair Prod" Square150x150Logo="Assets\Edge-Square150x150Logo.scale-400.png" Square44x44Logo="Assets\Edge-Square44x44Logo.scale-400.png" VisualGroup="FCA"></uap3:VisualElements> </Application> But when removing the ".scale-400" part of the files, the icons would not appear. Anyone knows what I am doing wrong here?
cant leave windows 11 insider program
Hello, i cannot leave the insider program. Im in windows 11 beta channel right now. If i try to leave the proramm by settings -> windows update -> windows insider program i have two options. I should be able to choose to leave the program with the next windows release, but this option is blurred out and i can not interact with it. The other option is the link at the bottom, which redirects me to a microsoft website. After logging in, it also tells me i can not leave the program now because my mail adress isnt registered. But u dont have another mail adress. I already contacted the support about that, the case number is 7034906605. We tried to create a new user and leave the program by this, but it also didnt work. I also did a windows reinstall with keeping my personal files and data. I would like to get around this issue without having to completely reinstall my windows because its a long process. Is there any way you can get my PC out of the beta insider program please? Greetings, Johannes.[FIXED] Anyone else having OneDrive high CPU usage problem after upgrading to build 19564?

I let it run like that for hours, hoping it will finish whatever it is doing but nope, it always stays like that. anyone else having this issue on the same exact build?
