You can remove the battery from your laptop and stay in hibernation for a week, then start back up and pick up right where you left off. Hibernation mode on your PC is similar to sleep mode, except the system saves all your open work to the storage drive and then shuts down. Now, let's look at what you can delete from Windows 10 safely.
Temporary files: As their name suggests, temporary files aren't used for anything in the long-term, so you can erase them without worry. Just make sure there's nothing inside it that you need. Recycle Bin: While you can empty the Recycle Bin through its own window, you can also do it easily here. Language resource files: If you've previously downloaded another language or keyboard layout that you don't use, this will let you easily erase it. You can erase these if you haven't had errors related to upgrading Windows to a new version. Windows upgrade log files: Similarly, these are data files that Windows Update keeps to help you dig into problems around upgrades or installations. These are safe to delete in most cases, but you should keep them for troubleshooting if you run into update-related issues.
Windows Update Cleanup: This erases old copies of Windows Update files. However, the following several options are low-hanging fruit (make sure to select Clean up system files first to see them all): This isn't a full guide to the Disk Cleanup tool, so we're not going to look at every option it offers.
