If you’re using Windows 10 Professional or Enterprise, the easiest way to disable Cortana is by using the Local Group Policy Editor.

Launch the group policy editor by pressing Windows + R, typing gpedit.msc into the box, and pressing Enter:

Navigate to Computer Configuration > Administrative Templates > Windows Components > Search.

Locate the Allow Cortana setting in the right pane and double-click it:

Set the Allow Cortana option to Disabled and then click OK:

You can now close the group policy editor. You’ll have to sign out and sign back in – or restart your PC – for this change to take effect.

In C:\Windows there is a system folder called “winsxs” which stores all the installation files used to update and upgrade Windows.

This folder, on my Windows 7 64-bit system, took up 12GB of space on my precious 80GB SSD drive.

Launch the DOS prompt with administrator rights and run the following command to remove all the files.

Dism.exe /online /Cleanup-Image /SPSuperseded

I learned today, it’s possible to create a symbolic link in Windows! Here’s what you need to do:

1. Run the DOS prompt as Administrator.
2. Use the following command as an example:

   mklink /D "C:\MSOCache" "D:\MSOCache"

3. Without the “/D” it’ll be a symbolic link for a file. To link a directory and all its files, use the “/D” option.
   The first variable will be the actual symbolic link.
   The second variable is where the files will actually reside.

When the machine first boots, the login screen defaults to the US QWERTY keyboard.
To change the default keyboard to something else, do the following:

My initial attempt to install Adobe CS2 onto Windows 7 64-bit (hereafter W764) was unsuccessful. W764 has two program folders:  “Program files” and “Program files (x64)”.

By default the installer will try to install into “Program files (x64)” and the unsupported characters “( )” make the path void. I changed this to the other “Program files” folder and continued the installation.

However, upon starting the programs, I was met with a “Your adobe photoshop user name, organisation, or serial number is missing or invalid” kind of error and the application quits automatically. Checking registry editor showed that there was indeed an issue with the installation paths.

Searching the problem on Google gave me the solution. The application must be installed into the “Program files (x64)” folder or it will not work. To do this, the path must be changed to:
C:\progra~2\adobe
in the  installation destination.
