Why is cpu usage always 100

This is usually OK, but it means that programs may slow down a little. In this case, you should find out which program is using up so much CPU time. This is because the computer will then try to use your hard disk as a temporary memory store, called swap memory. Hard disks are much slower than the system memory. You can try to free up some system memory by closing some programs. If things get too slow, try restarting the computer. While this process is sometimes associated with malware, it's primarily a legitimate and system-critical Windows process.

If you're unsure, use the svchost. In that case, just let Windows Update finish its thing. Since Windows 10, you can't easily delay or pause Windows Update. While you can schedule when to install new updates, Windows downloads updates as needed. This may randomly cause svchost. What you can change, however, is whether your computer shares downloaded updates with peers. Turn this off to conserve bandwidth and processing power. Here you can Allow downloads from other PCs , but you'll want this set to Off.

From Delivery Optimization , click Advanced options once more. In this next screen, you can limit the bandwidth of downloads or uploads of Windows and app updates. The only other workaround to tame high CPU usage related to downloading updates is to temporarily disable Windows Update. This will prevent Windows from downloading updates.

However, we don't recommend this solution! A background process is a program that's running on your PC, even though it's not open in a window. A typical computer will have many background processes running simultaneously, as Windows itself requires some to run. But as you install programs over the years, you may collect more and more and eventually overwhelm your PC. The Processes tab will appear by default, displaying not only overall CPU usage but also the usage of each app.

You should do this while no other programs are open to prevent confusion. In Windows 10 , head over to the Startup tab within the Task Manager.

In Windows 7 , exit Task Manager and open msconfig. For each driver in the list, additional useful information is displayed: load address of the driver, description, version, product name, company that created the driver, and more. Control Panel - Device Manager - Display Adapter - write down the make and complete model of your video adapter - double click - Driver's tab - write down the version info.

Always check in Device Manager - Drivers tab to be sure the version you are installing actually shows up. This is because some drivers rollback before the latest is installed sound drivers particularly do this so install a driver - reboot - check to be sure it is installed and repeat as needed. Manually look at manufacturer's sites for drivers - and Device Maker's sites. Please let us know the results and if you need further assistance.
