Windows Update, ESU, System Restore fail, fill C: drive
My C: drive on my laptop running Windows 10 Home has gone from about 20 GB free to 133 MB free after aborting Windows 11 installation, trying to sign up for ESU and trying several times to use System Restore to put things back the way they were. I'm hoping you can tell me where to look for the leftover files that are causing my C: drive to be so full. Here's roughly what I did, in order: I set Restore Points between the steps below. In Windows Update, chose to update from Windows 10 to Windows 11 24H2. After a lot of downloading, I got an error saying C: was full, that I should attach an external drive and remove about 5 GB from the disk. I tried for a while but realized that installing Windows 11 could fill my C: drive and make the computer useless. So I canceled the update. I read that ESU (which extends Windows 10 updates for a year) requires a Microsoft account to sign up. I only use local accounts because I'm often not on the Internet, and a Microsoft account requires me to be online. I created a Microsoft account with administrator privileges. From there, I ran Windows Update... but didn't see the option to join ESU. Then I went to the local adminstrator account and tried Windows Update again. I don't remember what happened, but I couldn't get ESU. The worst is that this changed my local admin account to a Microsoft account!! I tried System Restore to (I hoped) un-do the change to my local admin account, remove the Microsoft admin account, and un-do the files that were clogging my C: drive. But System Restore failed because there wasn't enough disk space. I tried earlier restore points, but for some reason they had been deleted. I started a chat with Microsoft support, then had to restart the chat after the first reboot during System Restore. The agents ran Disk Cleanup and also cleaned up various folders. That gave me about 3 GB free... not near the 20 GB I used to have. Luckily, the agent was able to restore my previous admin from a Microsoft account to a local account. What I think I need to know is what folders Windows Update, ESU, and System Restore use. I'm hoping I can go there, find the files changed yesterday afternoon / evening, and see that they take up nearly 20 GB... then I'd delete those files. For example, does ESU signup create C:\Windows\XYZ123? If you have any other suggestions, I'd sure appreciate them!
dbgeng.h: GetTotalNumberThreads Returns Incorrect Thread Count (According to DAC)
When writing custom extensions for Windbg to analyse user-mode crash dumps (using the IDebugSystemObjects4 interface provided by dbgeng.h), IDebugSystemObjects4-->GetTotalNumberThreads returns a smaller number than Strike/SOS. There is no documentation about where IDebugSystemObjects4 gets the thread count from -- it just states: The GetTotalNumberThreads method returns the total number of https://learn.microsoft.com/en-us/windows-hardware/drivers/debugger/controlling-threads-and-processes for all the https://learn.microsoft.com/en-us/windows-hardware/drivers/debugger/controlling-threads-and-processes in the current target, in addition to the largest number of threads in any process for the current target. (Emphasis mine.) Below is an example output from Windbg: 0:000> <Custom Windbg Extension Method Here> Getting IDebugSymbols... Getting IDebugSystemObjects... Getting GetTotalNumberThreads... Total Threads: 581 Largest Process: 581 Frames: 32 0:000> !threads ThreadCount: 587 UnstartedThread: 0 BackgroundThread: 26 PendingThread: 0 DeadThread: 47 Hosted Runtime: no Note that the IDebugSystemObjects4-->GetTotalNumberThreads method is returning 581 threads but Strike/SOS is returning 587. For what it's worth, https://github.com/dotnet/diagnostics/blob/6a90923439dc43693f2a2fc8766b3cdb2c4dd366/src/SOS/Strike/strike.cpp#L4358 -- which is, presumably, a different source than IDebugSystemObjects4 is getting the thread count from. Is this a bug in dbgeng.h? If not, is it because IDebugSystemObjects4 ignores finaliser threads; whereas those are not ignored when committed to the DAC? Also, sorry if this is the wrong place for this, I was thinking Windows SDK-related questions/bugs would fall under "Windows OS Platform".
Questions about Windows Server 2008 SP2 and Windows Server 2008 R2 SP1 support plans.
I have known that all the supports of Windows Server 2008 SP2 and Windows Server 2008 R2 SP1 has ended at Janauary 9th, 2024, the date where mentioned in Microsoft Lifecycle Policy. But I have found some updates which released after Janauary 9th, 2024, in Microsoft Update Catalog, and these updates will provide to these Operating System which have 4 years ESU license. So why does Windows Server 2008 SP2 and Windows Server 2008 R2 SP1 still can receive these updates after Janauary 9th, 2024? Does these Operating System has any additional support plans after that day? When will these OS doesn't receive any updates?
Automatic installation of Roots Updates
You can use the registry parameter to redirect the source of root certificate updates: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\AuthRoot\AutoUpdate "RootDirURL"="d:\......." Is it possible to automatically distribute certificates of intermediate certification authorities in this way?
ACPI EC OpRegion location
Hello, the ACPI specification defines OpRegions for ACPI bytecode to interact with devices, one suche device being the Embedded Controller. After looking at some example ACPI tables, it seems that Embedded Controller OpRegions can be defined anywhere inside the ACPI namespace, and not just inside the Embeeded Controller device scope. What is the Windows kernel policy for such OpRegions? Which Embedded Controller will be used to handle them (if any)? Thanks, Armin WolfMicrosoft's IPP driver keeps printing forever
Hi. I am not sure if this is the correct forum, but anyway. I have the following situation. I have a print server that I want to make compatible with the Microsoft's IPP class driver. This print server has multiple queues, and I am now in a state, where I can add each queue as a printer in Windows in combination with the IPP class driver. All good so far. The issue is, that when I delete one of the queues on the server, and I try to print some page through the corresponding IPP printer in Windows that I added earlier, the IPP client will try to retry the job every 10 seconds (or so) until I manually cancel it. The client behaves like this regardless of any error code I send to it from the server. I essentially tried all meaningful IPP error codes and all meaningful HTTP error codes. Still, IPP client keeps trying to send the job. Am I missing something? Is there a way how to force the client from the server to stop printing? The absence of any limit on the requests is quite inconvenient because multiple clients can be misconfigured and unnecesarilly overload the server. Thank you for any answer. PS: I am trying this on Version 10.0.19045 Build 19045
