Good evening.
Not sure your problem is only updates of apps.
Have-you clean temp file in your web browser like Firefox, Chrome...) ?
Some other apps create also cache file(s) like L:\LiberKey\Apps\XnView\App\XnView\cache\
XnView.db (L: is your letter drive) that can became big, for example 514 Mo on my PC because I'regulary use it . You can delete it when you restart and use XNview again it recreate it.
To verify what are the biggest files use
Windirstat for example.
