This “Hint and Tip” applies to all Windows 8.1 based computers, and earlier.

The following Windows updates add functions to Windows which are only used to collect data from your computer and send it to Microsoft. They can be safely removed and usually will help your computer run better as it no longer is trying to log everything and send it to Microsoft.
There are two ways to remove an installed Windows update. You can do it using the “Windows Update” tool from the Windows Control Panel. Start it and click on “Installed Updates” in the lower left corner.
Or you can do it from the command line prompt using the following command.
wusa /uninstall /kb:update_number /quiet /norestart
NOTE: Replace the word “update_number” with only the number in the update name (i.e. KB3068708 would be 3068708).
The following updates should be removed. Note that some of the updates may not be installed on your computer.
A word about KB2999226 and KB3118401. These two updates are described as allowing Windows 10 applications to run on earlier versions of Windows. They also allow Microsoft to install and test your computer for updating to Windows 10. Unless you are experiencing issues running software, which was designed for Windows 10 (does not apply to any game or utility which needs DirectX), you do not need either of these updates.
About KB3021917. This update sends telemetry information back to Microsoft notifying them whether or not your computer is Windows 10 compatible. That is all it does.
The above updates all have to with preparing your computer for Windows, or making Windows 7/8 computers supply Windows 10-like telemetry data to Microsoft. Many of them will hurt the performance of your computer as they are continually talking to microsoft about your system configuration.
Additionally, if you do not want to be bothered with the “Windows 10 Upgrade” notice in your system tray, remove the following update.
NOTE: This update appears to continue to be installed on computers even if you hide it in the list of updates.
KB3035583 is now set to re-install each time a new version of it is released from Microsoft. Microsoft has been changing it to combat those who are trying to kill the “Update to Windows 10” nagware utilities. A new version released now installs a program which checks registry settings twice a day to insure the user/owner of the computer has not manually tried to block the nagware.
Furthermore, if you manage to install more than one copy of KB3035583 (yes it is possible), then you will never be able to remove it and will not be able to stop the nagware.
There is a tool (GWX Control Panel) you can install which should help you take control of your computer again. All reviews/remarks about this program seem to indicate it is safe to install. For those of you who do not want to delve into the guts of Windows to stop the nagware, this could be a safe alternative, however The PCCA advises you to proceed at your own risk as we do not encourage anyone to dive into their computers beyond their skill level.
None of the above updates help your computer run better. In most cases, removing them will actually help improve the performance and stability of your computer.
Just be careful to type the numbers correctly.
After you remove the updates, you can go into “Windows Update”, find those updates, right-click on them and “hide” them. That way you are not bothered with them again.
