+=head1 WINDOWS TIPS
+
+Note that some of these tips modify the guest disk image.  The guest
+I<must> be shut off, else you will get disk corruption.
+
+=head2 RUNNING A BATCH SCRIPT WHEN A USER LOGS IN
+
+Prepare a DOS batch script, VBScript or executable.  Upload this using
+L<guestfish(1)>.  For this example the script is called C<test.bat>
+and it is uploaded into C<C:\>:
+
+ guestfish -i -d WindowsGuest upload test.bat /test.bat
+
+Prepare a regedit file containing the registry change:
+
+ cat > test.reg <<'EOF'
+ [HKLM\Software\Microsoft\Windows\CurrentVersion\RunOnce]
+ "Test"="c:\\test.bat"
+ EOF
+
+In this example we use the key C<RunOnce> which means that the script
+will run precisely once when the first user logs in.  If you want it
+to run every time a user logs in, replace C<RunOnce> with C<Run>.
+
+Now update the registry:
+
+ virt-win-reg --merge WindowsGuest test.reg
+
+=head2 INSTALLING A SERVICE
+
+This section assumes you are familiar with Windows services, and you
+either have a program which handles the Windows Service Control
+Protocol directly or you want to run any program using a service
+wrapper like SrvAny or the free RHSrvAny.
+
+First upload the program and optionally the service wrapper.  In this
+case the test program is called C<test.exe> and we are using the
+RHSrvAny wrapper:
+
+ guestfish -i -d WindowsGuest <<EOF
+   upload rhsrvany.exe /rhsrvany.exe
+   upload test.exe /test.exe
+ EOF
+
+Prepare a regedit file containing the registry changes.  In this
+example, the first registry change is needed for the service itself or
+the service wrapper (if used).  The second registry change is only
+needed because I am using the RHSrvAny service wrapper.
+
+ cat > service.reg <<'EOF'
+ [HKLM\SYSTEM\ControlSet001\services\RHSrvAny]
+ "Type"=dword:00000010
+ "Start"=dword:00000002
