Windows 10: ALL files have disappeared from my laptop after Windows update last week

tried to uninstall last update but it won't let me. tried to restore to last restore point but ' restoring files' just went on for 24 hrs so I guessed it was stuck so forced shutdown. Tried restarting several times to no effect. Getting a message saying my Onedrive is full if that's relevant

Task to auto update windows defender definitions disappears

My mom has a new laptop with windows 8.1, we always set the windows updates to manual.
On our other windows 8.1 computers I have created a task for auto updating windows defender definitions, which works fine for us.

This is how I created this task:

"Click on "Create Task", name it what you like (mine is Daily Signature Update), set the trigger as the time you want it to run every day.

For Action browse to Program Files\Windows Defender\MpCmdRun.exe and select it. In "Add arguments" add -SignatureUpdate -MMPC"

But somehow this task disappears once it has run on my mom's laptop.
I'm logged in as admin and then I also tried it with running the task scheduler as admin, the task just disappears every day for some reason, while it works fine on our other windows 8.1 computers.

Anyone an idea why this task disappears every time?

Thanks.

 

The option converting m4a files to wma files in windows 10 is disappeared

• What app are you using to convert the files?

I don't use any app to convert the files. I just copy the m4a files from my music folder. Then I paste the m4a files in my android phone drive that connected to my laptop. Then a windows pop-up that shows the option converting m4a files to wma files appears.
You can see the windows pop-up in below picture. Now the windows pop-up is disappeared.

• When did the issue start to happen?

I found this problem last week. However, I didn't convert m4a files to wma files since May, 2017.

• Were there any changes made to your device prior to the issue?

I updated windows several times prior to the issue.

• Have you done any troubleshooting steps so far?

I haven't done any troubleshooting steps.

 

Windows Updates failed to instal

I'm not sure how differant XP media center Edition is but you could clear the history \ cache if these folders are there.

Step 1 Register DLL files.

=================

By trying this step, we can check if the update engines are working properly.



1. Close all instances of Internet Explorer.

2. Click Start and Run, type "Regsvr32 atl.dll" (without quotes) in the Open box and click OK.



Note: There is a space between regsvr32 and atl.dll



3. Similarly, one by one, register the files listed below:



Regsvr32 msxml3.dll

Regsvr32 wuapi.dll

Regsvr32 wuaueng.dll

Regsvr32 wuaueng1.dll

Regsvr32 wups2.dll

Regsvr32 wucltui.dll

Regsvr32 wups.dll

Regsvr32 wuweb.dll

Regsvr32 qmgr.dll

Regsvr32 qmgrprxy.dll

Regsvr32 jscript.dll



Note: If you encounter errors while registering any of these files then skip that file and continue with the next one.



If the issue persists, let's move on to the steps below to verify Windows Update services and temporary folders.



Step 2 Verify the relevant Windows Update services.

=========================================

1. Click Start->Run, type "services.msc" (without quotation marks) in the open box and click OK.

2. Double click the service "Automatic Updates".

3. Click on the Log On tab, please ensure the option "Local System account" is selected and the option "Allow service to interact with desktop" is unchecked.

4. Check if this service has been enabled on the listed Hardware Profile. If not, please click the Enable button to enable it.

5. Click on the tab "General "; make sure the "Startup Type" is "Automatic" or "Manual". Then please click the button "Stop" under "Service Status" to stop the service.

6. Then please click the button "Start" under "Service Status" to start the service.

7. Please repeat the above steps with the other services:



Background Intelligent Transfer Service

Event Log

Remote Procedure Call (RPC)



Note: Event log service is enabled on all of the hardware profiles; this service does not have an option to enable or disable on certain hardware profile.



If it still does not help, let's proceed to step 3.



Step 3 Reload the Update temporary folders.

===================================

One possible cause is that the temporary folder for Windows Update is containing corrupted files. Let's erase all the files there to get the system clean.



1. Click Start, Run, type: cmd and press Enter. Please run the following command in the opened window.



Net stop WuAuServ



2. Click Start, Run, type: %windir% and press Enter.

3. In the opened folder, rename the folder SoftwareDistribution to Sdold.

4. Click Start, Run, type: cmd and press Enter. Please run the following command in the opened window.



Net start WuAuServ



Please test the Windows Update website and let me know the result. If the issue persists, to clarify the issue and provide more accurate troubleshooting steps, please assist me in collecting the following information.
