Windows Update fails working on windows 7 with Error Code 8024200D It may seem at first that we have many answers to this question but I tried them all but the update still fails.  Note: Windows 7 does not stuck in checking for updates. However, it downloads them but fails to install them : (No duplicates were found for this question).  Some of posts I've used to solve the issue:  Those all steps I have done:     1.  Stop the Windows Update related Services.    net stop wuauserv  // Ok : mean operation succeeded   net stop bits    // Ok   2. I deleted all files in:  C:\Windows\SoftwareDistribution folder and delete all the files and folders inside.    3. Restart the Windows Update related Services. net start wuauserv  // ok   net start bits      // ok        4. I have tried **Windows Update Troubleshooter** (WindowsUpdateDiagnostic.diagcab) : It said that the problems were     &gt; solved !         Another try, I have installed the last update of Windows Update Agent-7.6      6. Last but not least: I tried to install failed updates manually but installation failed and sometimes cause system failure to start (need revert changes).  7. I tried a clean boot : disabled all non microsoft and startup services. Still updates failed with the same error.  8. Finally, I tried both WSUS offline updater 10.9 and Windows update MiniTool. Both of them failed.   Without forgetting doing a full Virus/Malware analysis and removal :D    After doing all of those steps and restarted my laptop many times the problem is not solved so any other methods to try are welcome.

Windows 7 SP1 Windows Update stuck checking for updates I installed Windows 7 fresh and installed SP1. Now, when I try to check manually for Windows Updates it just hangs on the Checking for updates screen.    I tried running the tools in , but this did not fix the issue either:  No matter what I do it just hangs on the "Checking for updates..." screen and goes no further.
Finding the left and right cosets of H = {(1), (12), (34), (12) ○ (34)} in S4 I have an exercise where I am supposed to find the left and right cosets of H = {(1), (12), (34), (12) ○ (34)} in S4. But how do I generate the cosets? As I have understood it you are supposed to pick a number that is not in the set H and multiply it with every number in H. But this does not exactly give the right answer. I would really appreciate it if someone gave an easy to understand explanation of how to generate the left and right cosets. When I read about , I see that they should appear as solution to prevent  and  but when I actually try to write a code which would use Lightning promises it still doesn't look like synchronous code, it still resembles both pyramid of doom and callback hell.  main: function(component, helper) {     helper.promise1(component, helper).then(         $A.getCallback(function(record) {             return helper.promise2(component, helper, record).then(                 $A.getCallback(function(){                     console.log("Success");                     helper.showToastMessage(component, "Great Success!!!!")                 }),                  $A.getCallback(function(errorMessage){                     console.log("Rejected by second promise2");                     helper.showToastMessage(component, "Failure " + errorMessage);                 })              )         }),          $A.getCallback(function(errors){             console.log("Rejected by first promise1");             let message = errors &amp;&amp; Array.isArray(errors) &amp;&amp; errors.length &gt; 0 ? errors[0].message :'Unknown error';             helper.showToastMessage(component, "Failure " + message);         })      ) }   Is that possible to refactor this code to look more like synchronous code and without callback hell or pyramid of doom? So from what I remember it was on cable TV. The main hero was a TV actor zapped to a alien planet. It had a evil overlord with a virgin priestesses. She wants to get laid but he refuses because the next priestesses is only three. Regardless it's a parody things include a man who was maimed by the evil overlord wants revenge the hero eventually screws the virgin priestesses it cuts to scenes of a train going into a tunnel and a volcano erupting. Do you need to submit an itinerary to get a Russian visa? And do you have to stick to it? If I want to solve the equation $4x = e^x$, is there a way to solve for $x$ without graphing and looking for intersection? Ever since mods gained the ability to undelete comments, deleting them has become easier as the confirmation dialog was removed.  However, this is not the case in the mod queue &mdash; I still get a confirmation dialog for each comment I want to delete in the queue under a custom-flagged post (single-comment flags can be deleted just fine). And since this is the place from where I delete comments the most, it can be annoying.  In addition, the "purge comments" button, when invoked from the queue, refreshes it, so I have to scroll back down, remember which post I just purged, and mark the flag as helpful. Usually not a big issue but if there are multiple "obsolete comments" flags, then it can get confusing.  Could the workflow for comment thread moderation from within the queue be improved? Ideally, make comment deletion work like everywhere else on the site, and make the purge button AJAX-based like the comment deletes. To install the graphics driver I need to exit GUI / Gnome and go to the terminal. How can I do this in Ubuntu 18.04? Ctrl(STRG)+Alt+F1...F7 does not work, neither on the desktop, nor on the login screen... Classical limit of quantum mechanics I have heard that one can recover classical mechanics from quantum mechanics in the limit the $\hbar$ goes to zero.  How can this be done?  (Ideally, I would love to see something like: as $\hbar$ goes to zero, the position wavefunction reduces to a delta function and that the Schrodinger equation/Feynman path integral reduces to the Newtonian/Lagrangian/Hamiltonian equations of motion.) Is there a robust command line tool for processing csv files? Showing order of $Z (G) =1$ or $pq$ Question about mosfet gate resistor I have n mosfet gate connected to  logic and Id is about 100mA. Both 4043 and mosfet has +5v. I have plan to use  mosfet  Questions are: How large gate resistor i need between 4043 and mosfet? Logic output is sometimes put on rapidly. How fast? Motherboard hdd led controls that. Do i need to place pull down resistor from logic to -0v, between 4043 and mosfet? Posting and answering questions you have already found the answer to Sometimes you spend a day or more solving a technical problem, and when you finally solve it, you may want to post it on your blog (if you have one) to share with the community.  However, most developers don't have a lot of time to update their blogs, and that is why personal blogs are not ranked very highly on Google/Bing.  So even if you describe a brilliant idea, chances are that, except a few of your friends, nobody will ever find it. This is a common reason why some developers start their blogs and soon give up; it is not interesting to write for the community if you have no feedback on your posts.  Unlike personal blogs, Stack Exchange sites are highly ranked in Google (I was amazed when I saw that a question asked on SO just an hour ago appeared 3rd in my Google search!), so if your question and answer are valuable for others, they will be rated highly and will be visible for other developers.  With this in mind, is it good practice to post a question and answer it yourself immediately when you want to share an idea with the community? Find orphaned users In SQL Server 2005, is there a way to find users that either don't exist at the server level (an account that was deleted at server level but wasn't disassociated from databases before it was deleted) or accounts that aren't linked (an account may have been deleted at the server level but not db level, then readded but the db level was never cleaned up).  I've got a very messy server and it would be awesome if there was a query to run to find these. Is a passport needed when flying within Mexico as a U.S permanent resident? How do I run a program in the background of a shell, with the ability to close the shell while leaving the program running? Lets say my UI is having problems or for some reason, I need to boot up a program from the terminal window, say, nm-applet:  nm-applet   When it's started, it occupies the foreground of the terminal window.  Is there any simple way to run the program in the background without needing to leave the terminal open or have it occupy the whole terminal?  On that note, I did find a way to run programs from the terminal and have it allow for other inputs, by appending an ampersand (&amp;) to the command as such:  nm-applet &amp;   But this isn't much use as any processes started in the terminal are killed once the terminal is closed. Recover EXT4 partition I was trying to resize my EXT4 partition and something went wrong. I lost it. The space in once consumed is now being represented as Unallocated. How do I recover the partition? How to edit `postgresql.conf` with pgAdmin 3? I think that  is pretty good prima-facia evidence that  is just facilitating the deposition of crap.
