How to disable Fast User Switching in Windows

If it's not used properly, though, it can lead to problems as your computer becomes slow due to the amount of programs that are running at the same time. With this said, many people feel its better to disable Fast User Switching altogether and require people to log off of their accounts before another person can log in.

How to switch between accounts in Windows
Fast user switching is a feature in Windows that allows you to switch to another user account on the same computer without logging off. This allows multiple users to use the same computer while keeping each account's programs and files open and running in the background. As you can imagine, this can be useful when someone wants to use their computer but another account is logged in with open files and programs. Instead of taking the risk of closing the user's programs and possibly losing data, a user can instead just switch to their account without affecting the other one.

How to shut down or restart Windows
It is important to know how to properly shut down or restart your computer so that you do not lose data or corrupt important Windows files or Registry locations. Many people think that you shut down your computer simply by pressing the power button. On some configurations, this will work as Windows will recognize that you press the power button and shut it down gracefully. On the other hand, if your computer is not configured to do this, when you press the power button the computer will turn off and any unsaved data in Windows will be lost. Shutting down a computer this way could also cause data corruption on your hard drive or within Windows.

How to update Windows
When Windows, like any other operating system, is created there are bugs introduced into the software that could affect how the operating system runs. These bugs could cause Windows to not run reliably or could cause security vulnerabilities that would make Windows vulnerable to attacks. When these bugs are discovered, Microsoft creates updates to fix these issues and makes them available through the Windows Update utility. There is no set day that updates are released, except when it comes to security updates. Microsoft traditionally releases security updates for Windows on the second Tuesday of each month, which has become known as Patch Tuesday. In some cases, if a particular vulnerability is severe enough, Microsoft may release an update earlier in order to mitigate any issues that may be caused by this vulnerability. When Microsoft releases a security update ahead of schedule, this is called an out-of-band security update.
