I received a few pop up messages saying 86% of memory was in use, so I thought I would look and see if I could remove any memory-guzzling content to free up some space. I deleted all my bookmarks and then deleted a few apps for things I never use (games, Skype, Zoom etc...). I have now discovered that Excel and Word, amongst others that I also did not delete, have disappeared too! Is there any way that I can get these back, or undo all the deletions? I am not very tech savvy as you can probably tell. Thank you.
