One of the user is saying that his windows update taking 100gb of total storage. I wanted to see what is taking up that storage. I googled and most of the solution pointed towards windirstat. We cannot install unauthorized apps in our PC so was wondering if there is a native app that we can use see what specifically is taking up the space.
Is there more than one user profile on the machine? I had a situation once where an admin blocked permissions to a huge chunk of folders in their profile which resulted in the behavior you're seeing. Not saying that's what's happening but in my case once I re-stamped the proper file permissions to all those folders WinDirStat began to match windows. It's a shot in the dark but you never know.
Running as admin doesn't change anything. Also I've checked my recovery/restore options, and I've only allotted 18 GB, of which only 5.5% is being used, and windirstat/treesizefree take this into account.
I ran space sniffer as admin, and it found the hidden folder windirstat could not.40 GB of log files in c:\windows\system32\winevt\logs. Maybe I will just check archived event logs folder next time. Its huge, and its hidden.
I know that I could sort by size, but the nice thing with windirstat is that it shows filetypes and is more visual - by showing where specific filetypes reside in - if you have a folder with a lot of iso files and so on. (example)
