I had to free some space space on disk C: using treesize and soon I realized that I don't have anything that I can delete from user side do much so I was looking at big files in Windows directory and put my eyes on DataStore.edb 1GB size. After searching an looking on internet I saw lots of posts and article saying that there's no harm just that I will lose updates history that can be remade. So to be safe, I moved the DataStore file to my PC in case i will need it. Now I had lots of free space but short after I was having a lot less free space than I had before! less than 1 GB and Windows is asking for a restart to install update.. Datasore.edb is now arround 8MB After checking a little bit, i think Installer and winsxs folder filled up. Can this be fixed somehow ? It will free up after restart ? What could I do to fix this ?
