Disk Defragmenter cannot start because the task scheduler service is not running. Start the task scheduler service and try again.
In Windows 7, when I try to start Disk Defragmenter, I get this errot, "Disk Defragmenter cannot start because the task scheduler service is not running. Start the task scheduler service and try again."
Task Scheduler is set to Startup Type - Automatic, but it is not running. When I try to start it i get this error, "The Task Scheduler service on Local Computer started and then stopped. Some services stop automatically if they are not in use by other
services or programs."
Solutions to the Problem Disk Defragmenter cannot start because the task scheduler service is not running. Start the task scheduler service and try again.
Method 1: I suggest you to run sfc scan on your computer and check if the issue gets fixed.
SFC /scannow is a super-useful command you can use in any Windows version.
When the SFC (System File Checker) command is used with the /scannow switch, the tool will scan all of the important Windows files on your computer and replace them as necessary.
Missing and corrupt operating system files (like many DLL files) are arguably the biggest cause of major Windows issues.
Considering that, plus the fact that SFC /scannow is completely automatic and very easy to use, the tool should usually be one of your first
Click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.
If you are prompted for an administrator password or for a confirmation, type the password, or click Allow
Type the following command, and then press ENTER: sfc /scannow
[The sfc /scannow command scans all protected system files and replaces incorrect versions with correct Microsoft versions.]
A message will appear stating that 'The system scan will begin'.
Be patient because the scan may take some time
If any files require a replace SFC will replace them.
You may be asked to insert your Win7 DVD for this process to continue
If everything is okay you should, after the scan, see the following message "Windows resource protection did not find any integrity violations"
After the scan has completed, close the command prompt window, restart the computer and check.

How to use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7
Method 2: I suggest that you check the status of the Event log service.
This service should be started and set to ‘Automatic’.
Click on start and type ‘services.msc’ in the search field.
Select the services and look for the ‘Event log service’
Right click on service and click on properties.
From the dropdown, select the startup type to ‘Automatic’
Also try to run Disk Defragment on your computer.
Open Disk Defragmenter by clicking the Start button, clicking All Programs, clicking Accessories, clicking System Tools, and then clicking Disk Defragmenter. If you are prompted for an administrator password or confirmation, type the password or provide
Click Defragment Now.

Method 3: If nothing works, try to create a new user account and check if the task gets disabled after restart:
To create a new user profile, follow these steps:
Note: To create a new profile, you must first create a new user account.
When the account is created, a profile will also be created.
Open User Accounts by clicking the Start button, clicking Control Panel, clicking User Accounts and Family Safety and then clicking User Accounts.
Click Manage another account. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
Click Create a new account.
Type the name you want to give the user account, click an account type, and then click Create Account.
Note: Do not give the existing user name for the new user account.

How to Avoid Downloading Malware
Where are you getting the download?
There are malicious people who download valid copies of a popular download, modify the file with malicious software, and then upload the file with the same name. Make sure you are downloading from the developer's web page or a reputable company.
Don't install download manager
Many sites suggest or require you to install an installer or a download manager before allowing you to download a program you may be interested in downloading. These tools almost always cause your computer more problems and may even have malware or other spyware. Avoid any site claiming anything must be installed first before you can continue with your download.
Avoid advertisements on download pages
To help make money and pay for the bandwidth costs of supplying free the software, the final download page may have ads. Watch out for anything that looks like advertisements on the download page. Many advertisers try to trick viewers into clicking an ad with phrases like "Download Now", "Start Download", or "Continue" and that ad may open a separate download.
Cancel or deny any automatic download
Some sites may automatically try start a download or give the appearance that something needs to be installed or updated before the site or video can be seen. Never accept or install anything from any site unless you know what is downloading.
Another Safe way to Repair the Problem: Disk Defragmenter cannot start because the task scheduler service is not running. Start the task scheduler service and try again.:
