There are two kinds of methods, one using group policy and the other blocking from registry, but in either case, you first need to install the update that is distributed by Windows Update first.

◆ Installing updates

◆ How to prevent installation with Group Policy
Since the method using Group Policy can not be used with Windows 7 Home Premium and Windows 8.1 (No Mark), please refer to the method using the registry described below.

First of all, in the search box in the start menu,Gpedit.msc"And click" gpedit "that came out.


The Local Group Policy Editor will now launch.


Follow the tree of "Computer Configuration" → "Administrator Templates" → "Windows Components" and open the "Windows Update" item, there is a line written as "Turn off the upgrade ~~" so double click Open in.


Check "Enable" and click OK. That's all there is to it.


◆ How to suppress installation in the registry
Another way is to modify the registry. In the search box of the start menu,RegeditPlease enter "regedit" that came out.


The Registry Editor starts.


It is a tree which is considerably longer than the local group policy editor, but it follows "HKEY_LOCAL_MACHINE" → "SOFTWARE" → "Policies" → "Microsoft" and moves to where you can see the contents of "Windows". If there is no key "Windows Update" at the bottom of the Windows key tree, create a new one yourself.


Right click on "Windows" key and select "New" → "Key".


Then a key named "New Key # 1" is created. Press the F2 key to change the name "Windows UpdateI will name it. Do not put a space between "Windows" and "Update" Thank you very much.


Next, click the "WindowsUpdate" key just created. Since there is only a character string named "(default)" on the right side of the screen, right click on the vacant place and select "New" → "DWORD (32 bit) value (D)".


"New value # 1" has been created.


Also press F2 to rename, "DisableOSUpgrade"will do.


With "DisableOSUpgrade" selected, right click and then click "Modify".


Enter "1" in the column of value data and click "OK".


It is completed if "Right end of" DisableOSUpgrade "is" 0x00000001 (1) ".


For Windows 8.1, right click the start button on the desktop and click "Run (R)". Or you can also use Windows key + R.


Enter "regedit" and click "OK"


Since Registry Editor starts up, it is OK if you follow the tree like in Windows 7 and set the DWORD value "DisableOSUpgrade".
