Software we will install on Windows virtual machine will show up on all Client PCs of the laboratory and can be used by all users. So we maintain one Windows installation for many workstations.

We should not execute setup files from our personal network folder X:\ (My Documents) or directly from a usb stick, installation may fail this way. Instead we create a temp folder on C:\, copy setup there and execute from C:\temp. After installation we delete setup file. Keep in mind also, that we have a storage limit on our personal folder X:\ (My Documents) so downloading a big file should be saved directly on C:\temp.

Installing specific applications like MSOffice while connected with our network personal user with administrator rights may fail. To solve this we connect as a local administrator .\Administrator or .\root and retry installation

In case there is no installation file and we only need to do a simple copy to install and we need also to create a link in the desktop of all users, we do the following :

• We copy the program folder e.g. newprogram inside the folder C:\opt (we create if it doesn't exist)

If we have installed without an installation file or from an installation file but no shortcuts to the desktop were created we do the following:

• We login as local administrator .\Administrator or .\root
• We enter the folder where the program was installed and drag the executable to our desktop to create a shortcut.
• From My Computer we enter C: folder.
• We click on addrees and type manually C:\Users\Public\Desktop and press ENTER to see folder contents
• We copy the shortcutwe have created previously from our Desktop to folder C:\Users\Public\Desktop.

This installation is applicable while

This is the easiest way to install. We do the following. We download the installation file from the Internet and save to folder C:\\temp. Then proceed with the installation.
