Fix Windows Update Error 0x80070643 on Windows 10

what you guys going to be going about fixing this Windows Update error 0 X 800 706 for free and we're going to be taking a look at how we can try to resolve it in this video now if you are running Windows Defender you may get an error message when you try to update your Windows 10 machine and I'll show you what the error looks like right now so you go down to the settings pane here and then you go to update & Security and you click on check for updates what generally happens is it will start checking for updates and then you'll get an error kicked back in the update error box at the top here you can see that's the error it's kicking back so we're gonna go ahead and try to fix and resolve this issue you can see this one these definitions are update for Windows Defender so the first thing we're gonna do here is come down to the search box and type CMD right click on this and run this as administrator this will open up the command prompt box so I'm just gonna type and paste these commands in now what this is going to do is remove all of the definitions on this machine and the reason why I want to do that just in case they're corrupted and then I want to run this command underneath and this is going to download all the latest signature updates for Windows Defender so we've removed all of the definitions on Windows Defender and now we're going to install all the latest ones just in case there's a corruption there somewhere and that's the what we're gonna try first so once we've done that we should be ok there so what we're going to do is move on to the next step there obviously if this is resolved to ich you don't need to continue but if you are still having issues you may want to open up troubleshooter but putting troubleshoot inside the search box going to Windows Update section and run the troubleshooter from here and this will try to fix any issues that you've got with the Windows Update there may be a problem with it and if there is you can apply the afix so you can see here it's gonna apply this fix I'm just going to quickly apply this and it will run through another bunch of tests and now we can apply this fix as well hopefully this will resolve the issue but if it doesn't I'll show you some other things that you can check and try to fix and resolve your problem so we'll just let this finish off let me go potential potential Windows Update database error detected so I'm going to close this box off here and we're going to do next is try to fix the dotnet framework now sometimes the dotnet framework can kick up an error I'm gonna download the repair tool for the dotnet framework so what I'll do is I'll download this and we'll run this and hopefully this will repair the dotnet framework on this Windows 10 machine just in case there's an issue there so I'm just gonna accept their terms go next and let it go ahead you can see here rear edge the Windows installation service and a bunch of other things here so we're going to go next here and let it repair this so go next I know what this will do is it will collect a load of logs and you'll be able to check those logs out and try and find out where the error is sometimes this does point to the dotnet framework and there's the path for all those actual log files that is created so we can finish this one off and move on to another fix if there's ant this hasn't resolved your issue just move on down to the search area here and we're going to type in here CMD again and run this as administrator again little command prompt box will open up now we're going to do SFC space forward slash again and what this is gonna do is scan for any corrupt system files or any problems with the operating system so just let that run through and hopefully this will resolve the issue so this will take a bit of time so you're just gonna have to be patient and let this run through so you should see a little counter there going down percentage-wise I'll speed this process up 90% 99% there we go and then what it will do is it will display some information down below here and you can see windows a resource protection found corrupt files and success successfully repaired those and now what you can do is run this one here and this one is the disome command so we're just gonna run this one as well because I've got problems here so just type that into the command prompt box there I will leave all of these commands in the video description so you can just copy and paste them like I'm doing here this makes it a lot easier save you typing them out and then once you've entered that in again this will take a bit of time so be patient just leave the Machine alone let it work away but I'll speed this process up so it doesn't take too long there we go so what it's done now that this is restored the operation complete successfully so that's now done I'm going to move down to the search box I'm going to type CMD again and run this as administrator here so we're going to do now is inside the command prompt box we're going to rename the software distribution folder so I'm going to stop some services here and there you can see the bits we're gonna stop this and we need to stop these so we can actually rename the software distribution folder to software distribution dot back now this is where all your updates that you've been downloading are stored and when it installs them and once we finished rename we can restart these services here so I'm just going to go ahead and restart these now we've renamed it and I'll show you exactly what it's done in a second here let me just quickly go to that location which is a Windows software distribution now what can happen is sometimes this gets corrupted and you need to clear this out but you can't just delete all the contents in it because obviously is in use so you need to stop those services so you can empty that folder out and you can see I've created a backup just in case here now yours may be gigabytes in size being see there's a new one windows will automatically create a new one soon as you rename the old one next we need the cap root to folder to be emptied and we can do this by typing these commands out here so you see I'm making a backup of the original folder so it's always advisable to make a backup of the original folder and now we can delete all the contents inside that cat root to folder so we need to do here is go to that location and delete all the contents inside here and this is in system 32 now course you can create a batch file to do this all for you if you want to I do have those on my forums but you can go into heating see it's created a backup here so I'm just gonna go inside here and delete these contents inside here now sometimes what can happen these get corrupted as well and by doing this it just helps with the updates and sometimes it can resolve the issue so I'm just going to quickly delete those ok so they are all removed now we can restart those services again so you go net start so it didn't it stopped just to stop it and then let's start with the service that you want to start at the end so we're going to start that up and what we're going to do here is go down to settings here and see how we are going update and security and see if our probably has been resolved so just let that check for updates if we get an error message then we're still got an issue but if it is resolved you should start getting your downloads for your updates coming down so still check in and there we go you can see the definition updates for Windows Defender is now starting to come down we're not having and only issues there so that means our problem has been resolved it's now starting to install and that's basically how you can resolve that issue anyway that's about it for this
