Manually uninstall Office 2016 or Office 365

NOTE   Before you start, you need to know removing Office manually is a long, complex process and might require that you reinstall the operating system if certain steps are done incorrectly.

You'll need to determine your Office installation type so you can choose the correct way to uninstall it:

• Click-to-Run is a new way to install and update Office over the Internet and it works similar to streaming video. By default, Office 365, including Office 2016 products are installed by using Click-to-Run.
• MSI, (also known as the Microsoft Windows Installer), is the traditional way of installing Office via a local installation resource.
  To determine your installation type
  1. Start an Office application, like Word.
  2. Click File > Account.
  3. If Office 2016 was installed using Click-to-Run, an Update Options appears. For an MSI installation, theUpdate Options are installed through Windows Update only.

What is the Difference Between Log Off, Restart, and Shut Down?

To shut down (or power down, or power off) a system means that, when the process of shutting down is complete, the machine is powered down, and it will not come back up again without a someone taking further action, e.g., powering it back on again. If you expect your system will be needed for maintenance or remote access by someone else, shutting it down effectively prevents this.

To power on a system means that you simply press the power button and let the system come up to a login prompt.

If you enter your username and password, you have gone a step further and have logged on.

To restart (or reboot) a system means that the computer goes through a complete shutdown process, then starts back up again. This is frequently required after software installations or during troubleshooting.

To log off or Sign out a system means that the user who is currently logged on has their session end, but leaves the computer running for someone else to use. This is faster than a full restart and, generally, a better choice during the course of the business day when a system is shared between multiple users.

To Switch account means you will be leaving current user behind (not logged out) and attempt to login using your credentials. this will take lot of memory from the computer RAM. as a result computer will be very slow. also this will prevent others using the same documents opened in other users. so the best way is to sign out from the user before login to another.

How to turn on automatic logon in Windows - Windows 10

Summary

This article describes how to configure Windows to automate the logon process by storing your password and other pertinent information in the registry database. By using this feature, other users can start your computer and use the account that you establish to automatically log on. 

Important The autologon feature is provided as a convenience. However, this feature may be a security risk. If you set a computer for autologon, anyone who can physically obtain access to the computer can gain access to all the computer's contents, including any networks it is connected to. Additionally, when autologon is turned on, the password is stored in the registry in plain text. The specific registry key that stores this value can be remotely read by the Authenticated Users group. This setting is recommended only for cases in which the computer is physically secured and steps have been taken to make sure that untrusted users cannot remotely access the registry.

Use Registry Editor to turn on automatic logon

Important This section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

How to format USB - use same commands if you don't see full capacity of your USB or flash drive

When re-formatting the "drive" you're actually only formatting a partition on the drive. You need to use the diskpart utility to remove the partitions and create 1 single partition covering the full volume.

diskpart can be a bit dangerous, because if you pick the wrong disk or partition, you can remove data or partitions that are extremely, EXTREMELY important and lose all data on your machine.

Proceed with extreme caution!

Open up a command prompt as administrator (open the start menu, type cmd and press Enter.)

Type diskpart and press Enter. You'll end up with a new prompt that looks like this:

DISKPART>

Type

list disk <ENTER>

and you'll get a listing of all drives on your machine.

Type

select disk # <ENTER>

to select a disk, where # is the number of the disk Windows screw-balled. Usually, the device is disk 1, but it's always best to make sure.

Then type

list partition <ENTER>

to get a listing of all partitions on the disk.

If you're sure you have the right disk/partition, you can then repeat typing

select partition # <ENTER>
delete partition <ENTER>

until all partitions are removed from that drive.

Once the drive is empty, exit diskpart and remove the drive. Wait at least 5 minutes, then re-insert the drive. DO NOT CLICK FORMAT – this will most likely re-create the problem. Instead, enter diskpart again, and select the disk. Then type

create partition primary <ENTER>

Once you have created the partition, exit diskpart and, in the command promt, type

diskmgmt.msc <ENTER>

This will provide a reliable way to create a FAT32 partition. On the drive you would like to format (NEVER TOUCH DISK 0!), right click and select format. The allocation unit size option should be default, and the File System option should be set to FAT32. The format may take a while, depending on the disk size, be patient.

This should fix partition troubles on any readable USB flash drive.
