 ## wCenterWindow

+Program icon made by Kirill Topov.
+
+---
+
+This program centers the current active window by a `LCTRL + LWIN + C` hotkey, or pressing `LCTRL + LWIN + MMB` (Middle Mouse Button).
 
 `LCTRL + LWIN + V` - manual editing of size and position of the window.
 
-You can use `LCTRL + LWIN + I` hotkey for hide/show trayicon.
-You can also use commandline option `/hide` for hide trayicon at startup.
+`LCTRL + LWIN + I` hotkey is used to hide/show trayicon.
+You can also use commandline option `/hide` to hide trayicon at startup.
 
-`Use workarea` option means that the window is centered without a taskbar, otherwise, the full resolution of the monitor will be used.
+The `/noupdate` commandline option is used to disable check for updates. By default, the program checks for updates upon startup and once a day.
 
-If some windows does not centers you should run wCenterWindow with administrative rights.

 ## Automatic startup
 
-Usually, to start the application when Windows starts, it is enough to put the application's shortcut in the "Startup" folder -\
-"C:\Users\[*Your user name*]\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup". (The easiest way to get there - press 'WIN + R' and type 'shell:startup').\

+"C:\Users\\<*Your user name*>\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup". 
+(The easiest way to get there - press 'WIN + R' and type `shell:startup`).<br>
 However, in this case wCenterWindow will not be able to work with windows that are open with elevated privileges.
-And if you enable the "Run as administrator" option in the shortcut, then wCenterWindow will not start. This is related to the security of Windows (maybe only in 10/11, I did not check).\
-This behavior can be bypassed by creating a task in the Task Scheduler with the "Run with highest privileges" option.\

 **Note:** If you run wCenterWindow via the Task Scheduler, I highly recommend enabling the "Delay task for" option for 15-30 seconds, otherwise you may get an error message "Can't create tray icon".
