### Describe the improvement

Would be nice to have a once-a-month check for updates for applications.
This is helpful for those of us using our personal computers infrequently, who see the helpful UniGetUI app pop up every time we turn on the computer. For me, 1x / monthly can tie in with Windows Updates and get it all done at one time.

If there is a way us geeks could execute the "update check" by command line/powershell and create a scheduled task that would suffice for me!
Perhaps if there is an option to open UniGet when there are updates, after this check?
I realize this is similar to Issue #647 ( https://github.com/marticliment/UniGetUI/issues/647 ), hopefully this provides a different approach that could be easily solved. Thank you!
