Windows 7 - The task image is corrupted or has been tampered with

I tried to create a job to shutdown MY pc one hour from now, I got the error :- The task image is corrupted or has been tampered with

Here is the solution, that worked with me.

Recreate the task by deleting the corrupted task
a. Click Start, type task scheduler and hit enter.
b. In the left pane, click on "Task scheduler library" and select the backup task in the middle pane and delete it.
If you’ve trouble finding the corrupted task, follow the steps mentioned below.
     i.       Click on Start; in the start search type cmd. In the programs list, right click on cmd and run as administrator.
    ii.       Now execute the following command.
schtasks /query | findstr /i


To schedule the shutdown,

To make your computer shutdown at a particular time, 

type taskschd.msc is start search and hit Enter to open the Task Scheduler
In the right panel, click on Create Basic Task. 
Give it name and a description if you wish and click Next. 
When asked When do you want the task to start, select One time.
Select the Start date and time.
Clicking Next will bring you to the Action page. Here select Start a program and click on Next.
Here type shutdown on the Program/script space and –s –f –t 0 in the Add arguments box. If you want the shutdown to commence after say 60 sec, type 60 instead of 0 here.

Windows:- Windows 7 upgrade to Windows 10

I upgraded windows 7 to Windows 10. It took about about 3 hours to upgrade. I thought its going to be very slow. Finally, its completed and upon reboot, it was really slow. After clocking on Internet Explorer, I can go for coffee and comeback, its still loading. Super slow.

Finally, I decided to backout to windows 7. Here are the steps how I backout the system.

=> Click on start menu and click on Settings
=> Click on Update & Security 
=> There are couple of options here. You can reinstall Windows 10 or you can reset. 
Since I planned to go back to Windows 7, I click on Recovery.
=> You will see an option to Go back to Windows 7.
=> Click on Get started to go back to Windows 7.

Finally, I am happy with my old Windows 7. Its way faster than Windows 10.
