Allocated memory space from software applications that are no longer open can cause problems. Over time, this unused memory space can build up, causing Windows to slow down and use the hard drive more. These memory leaks are causing the system to slow down if the computer runs well when first turned on, but performs noticeably slower after several programs are opened and closed.
Memory leaks can happen when software is closed before it has fully opened. Always allow apps time to fully open before closing them. As a rule, wait five seconds after an app opens before closing it again, even if the app was opened unintentionally.
On rare occasions, an incompatible app might continue to allocate memory while it is running, causing the system to slow down and eventually lock up.
To immediately fix memory leaks, restart the computer. For a permanent fix, isolate software applications that might be causing the leaks.
note:
For information on your computer’s memory requirements, please see the specifications document for your computer model.
To isolate apps that cause memory leaks:
-
Restart the computer.
-
From the Start screen, type task manager to open the Search charm, and then select Task Manager from the search results.
Task Manager opens.
-
At the bottom of the Task Manager window, click More details.
-
Click the Performance tab, and then click Memory to view the amount of available physical memory.
-
Click Open Resource Monitor to view how your computer is using the memory.
If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
-
In the Overview tab, click the arrow to expand the Memory section, and then scroll down to view which apps are using memory.
-
Open an app suspected of causing the computer to run more slowly.
-
Check the percentage of Used Physical Memory, and then write it down.
-
Close and reopen a suspected app repeatedly, and then check the percentage of Used Physical Memory, comparing this number to the one recorded. Each time, wait about 10 seconds before opening the app again.
-
If the percentage of Used Physical Memory continues to increase, there is a memory leak. Contact the software manufacturer for available patches or fixes.
-
If the Used Physical Memory percentage returns to the same numbers or similar each time, the suspected app is probably not creating a memory leak.
