You still have the ability to place your computer in sleep mode, which gives you the ability to save the state of your computer into memory instead of on the hard drive.

This maintains your computer in a power-on state but which is, however, low power. The basic concept of virtual memory is that if your computer has physical memory that is insufficient to execute an operation or run a program, Windows will execute data moves temporarily to a paging file present on the hard disk from RAM memory.

These are the necessary steps. For reasons related to performance, you should always use a paging file.

These steps can help you free up to a few gigabytes of space on your hard drive by limiting the amount of space that is taken up by Windows on your computer.

Unlike previous versions, Windows 10 does not require or use a recovery image. The way Windows 10 is implemented, the OS uses the files present in the system already. To be more specific, the files can be found in the winsxs subfolder inside the Windows folder. Having said that, there is indeed one more additional component in the form of a compression mechanism known as Compact OS.

The way this tool works is that it takes the Windows 10 files and places them into a hidden container where they are actually compressed. This helps to reduce the amount of space required. Compact OS is a lot easier to both configure and deploy. This is how to run Compact OS:. This tool will start the operation of the process, which will take between 10 and 20 minutes. What is even better is that we do not even need to restart the computer. There are a few different ways to reduce the Windows 10 ISO file size, including disabling hibernation, uninstalling default apps, and adjusting the virtual memory settings.

Most of the default apps can be uninstalled through System Settings Programs and Apps. Disabling hibernate also saves space by deleting the hiberfil. Why does Windows 10 take up so much disk space? Windows 10, though much smaller than previous versions, still takes up about 15 GB of storage space. Much of this is from reserved and system files, though about 1 GB is solely from default games and apps.

File space is also used by hibernation support files hiberfil. For example, when the system commit charge is more than 90 percent of the system commit limit, the page file is increased to back it. This continues to occur until the page file reaches three times the size of physical memory or 4 GB, whichever is larger.

This all assumes that the logical disk that is hosting the page file is large enough to accommodate the growth. The following table lists the minimum and maximum page file sizes of system-managed page files in Windows 10 and Windows Several performance counters are related to page files. This section describes the counters and what they measure.

The following performance counters measure hard page faults which include, but are not limited to, page file reads :. Hard page faults are faults that must be resolved by retrieving the data from disk. Such data can include portions of DLLs,. These faults might or might not be related to a page file or to a low-memory condition. Hard page faults are a standard function of the operating system. They occur when the following items are read:.

High values for these counters excessive paging indicate disk access of generally 4 KB per page fault on x86 and x64 versions of Windows and Windows Server. This disk access might or might not be related to page file activity but may contribute to poor disk performance that can cause system-wide delays if the related disks are overwhelmed.

Therefore, we recommend that you monitor the disk performance of the logical disks that host a page file in correlation with these counters. Be aware that a system that has a sustained hard page faults per second experiences KB per second disk transfers.

No performance counter directly measures which logical disk the hard page faults are resolved for. Not all the memory on the modified page list is written out to disk. If a system is configured to have more than one page files, the page file that responds first is the one that is used. This means that page files that are on faster disks are used more frequently. Be aware that actual page file usage depends greatly on the amount of modified memory that the system is managing.

This means that files that already exist on disk such as. Only modified data that does not already exist on disk for example, unsaved text in Notepad is memory that could potentially be backed by a page file. After the unsaved data is saved to disk as a file, it is backed by the disk and not by a page file. Skip to main content. This browser is no longer supported. Download Microsoft Edge More info.
