How to schedule a Batch File to run automatically in Windows 10 / 8 / 7

RECOMMENDED: Click here to fix Windows errors and optimize system performance

There are occasions where you might need to schedule to run a batch file automatically in your Windows. In this article I’ll suggest a tip on how to schedule a batch file automatically using Task Scheduler.

Schedule a Batch File to run automatically

Step 1: Create a batch file you wish to run and place it under a folder where you have enough permissions. For example under C drive.

Step 2: Click on Start and under search, type in Task and click open Task Scheduler.

Step 3: Select Create Basic Task from the Action pane on the right of the window.

Step 4: Under Create Basic Task, type in the name you like and click Next.

Step 5: From the Trigger select the option you like and click Next.

I chose Daily and clicked Next, which brought me to this screen.

Step 6: Then click on Start a Program and click Next.

Step 7: Now click on Browser and select the batch file you like to run.

Step 8: Finally, click on Finish to create the Task.

Now that we have created a Task, we have to make sure it runs with the highest privilege. Since we have UAC settings we have to make sure that when you run the file it should not fail if it does not bypass the UAC settings.

So click on Task Scheduler Library.

Then double click on the Task you just created.
Step 8: Click on Run with Highest privilege then click OK.

Congratulations!  You have successfully created a Scheduled Task to automate a batch file.

How to: Rollback to a previous version of Windows from Windows 10

NOTE: Please be aware the Windows.old folder located at the root of the local disk where Windows 10 is installed will be deleted after 30 days automatically. The Windows.old folder is used to facilitate the rollback. So please perform any rollback within 30 days or this option will no longer be available. Otherwise, create a backup before upgrading to Windows 10.

See links to resources about backing up by clicking the link for the respective version of Windows you are running: Windows XP, Windows Vista, Windows 7, Windows 8/8.1

Summary

Throughout the history of Windows revisions, Microsoft has included an option to uninstall the operating system when you upgrade to a newer version. My recollection of this capability goes back to Windows ME which included the option to uninstall the operating system and restore to a previous version of Windows (I was running Windows 98 SE at the time). Microsoft has supported this functionality in its NT based versions of Windows too, albeit not in a seamless way. The ability to restore a Windows 8.1 installation to Windows 7 required knowing some command line operations that in some instances didn’t guarantee the process would go according to plan. With Windows 10, it seems Microsoft has listened and has provided a welcome option to its recovery tools to make it easy to uninstall Windows 10 and go back to your previous version of Windows. This option can be handy for diagnostics purposes, trial and error or to simply go back to a previous version of Windows that works better with your PC.

Please keep in mind, this only works with Windows 7 and later. Because prior versions of Windows such as Windows Vista and Windows XP can only migrate to Windows 10 through a custom install, the command line operations remain your best choice if you do decide to go back. Also keep in mind, if you do a custom install over Windows 7 or later, the Rollback option is not available. This only works if you had done an in place upgrade from Windows 7 or later.

Start by opening Settings – Click Start > Settings or type Settings in the search bar and click it or press Windows key + i

Click Update and Security

Click Recovery then click Get started under Go back to Windows 7 or Windows 8/8.1 (depending on the previous version you running)

Here you can make multiple selections why are going back to your previous version of Windows along with additional details or you can choose just one and click Next.

As noted, any configurations made to Windows 10 since upgrading will be lost, so if you installed new programs or hardware drivers or made personal settings, those will be deleted.

Click Next

Make sure you have your password ready to sign into your old version if you had been using one. Click Next

The process can take a while depending on the amount data, applications and settings. Click Next

Click Go Back to begin the process.

Windows 10 will Restart

This will be your screen throughout the recovery process.

When the process is complete, you will be booted into your previous version of Windows environment.
If you cannot load the Windows Desktop, you can initiate a Rollback using the following method:

Log out and go to the sign in screen.
Hold down the shift key on your keyboard while clicking the Power button on the screen
Continue to hold down the shift key while clicking Restart
Continue to hold down the shift key until the Advanced Recovery Options menu appears

Click Troubleshoot

 Click Advanced options

Click Go back to the previous version of Windows

Try re-installing Win 7 using the Win 7 DVD, or restore from a backup that you have.

Ubrales advised you well, but if you want to try Win 10 again, do it the same way. I hear a lot of complaints and bad vibes from people trying to upgrade. I did a clean install (on 2 different machines) and could not be happier. Burn a DVD or make a USB (better, faster). Get it here:

SD Card Formatter

Reference website:

SD Formatter 4.0 for SD/SDHC/SDXC

This software formats all SD memory cards, SDHC memory cards and SDXC memory cards. SD Formatter provides quick and easy access to the full capabilities of your SD, SDHC and SDXC memory cards.

The SD Formatter was created specifically for memory cards using the SD/SDHC/SDXC standards. It is strongly recommended to use the SD Formatter instead of formatting utilities provided with operating systems that format various types of storage media. Using generic formatting utilities may result in less than optimal performance for your memory cards.

The SD/SDHC/SDXC memory cards have a "Protected Area" on the card for the SD standard's security function. The SD Formatter does not format the "Protected Area". Please use appropriate application software or SD-compatible device that provides SD security function to format the "Protected Area" in the memory card.
