You can run system tools such as Disk Cleanup and Disk Defragmenter to make the system run faster. Make sure that you clear temporary internet files and cookies periodically. You can also uninstall all the programs that you do not use to improve the performance of Windows.

In addition, you have to leave sufficient free space in the drive in which Windows is running, i.e., C drive in most cases. Similarly, do not save too many files in the Desktop folder or create too many short cuts there.
