If you do not want to install Windows 10 on your computer, then you do NOT want (and do NOT need) KB2952664.
You can hide KB2952664 (and any other update that you do not want) as follows ...
- Look through the list of Important update, and the list of Optional updates, in Windows Update.
- Find the update you want to hide.
- Right click the update; a drop-down list will appear near your mouse pointer.
- Click the item in the list that says "Hide".
- A pop-up may appear asking permission.
- The update will then appear as "greyed out".
- Repeat for any other updates you want to hide.
- The next time you open Windows Update, the update(s) you have hidden will not be listed .... until Microsoft unhides them. When that happens, follow the above steps to re-hide the updates. Microsoft does not know the meaning of the word "NO" ... as in "NO, I do NOT want Windows 10 installed on my PC." ... so they will periodically unhide updates that the user has previously hidden ... that's why you should NEVER set your Windows Update setting to "Install Updates Automatically".
In order to prevent Windows 10 from being installed on your PC, I suggest that you use one of the following:
- GWX Control Panel. Here is the web-site:
