There is one good solution (it has worked for me many times) to make your PC (and therefore all applications) runs faster and more efficiently. The simple trick is to create a new Windows local account (i.e. profile) and remove the previous one: https://www.windowscentral.com/how-manage-user-accounts-settings-windows-10 I try this, say, every two years because, among other reasons, its size could become really ridiculous! For instance, I had just created a new account to replace the previous one with a size around 30GB (thirty GB!). Since the Windows accounts are installed in the C:\users\ folder, find out the name of your current account by opening a command prompt (Win Key + R, then type cmd, then hit OK), and type 'whoami' (that is, "Who am I?") and then press Enter to see C:\Users\[MyAccount], but normally that information is already there without typing any command. Then, in the File Explorer, right click on the folder with that name and select Properties. You will see its size which can go from a few GB to more than 20GB and that's when I think there is a problem. You will have to recreate all customized settings in the new account, but most of the times all installed software will work fine simply because everything is in the same computer. CAVEAT: if you keep all your documents in the C:\Users\[MyAccount]\Documents folder you will have to move them to the corresponding new account folder and change all existing links, for instance, in Studio. Another tip: forget about this default folder to save documents. Create a new partition, say, the D: drive, and keep all your production and backup documents, TMs, termbases, etc. there. Leave the C: drive exclusively for the operating system (Windows) and to install all types of software.
