Windows 7 is slow. RRS feed

  • Question

  • Hello.

    My Windows 7 is slow. I did check disk and "sfc /scannow" but not found any problems. When I use "Diagnostic startup" then it is OK. How can I find the problem?

    Thank you.

  • Here is my growing list of things that could be responsible for slowing the start up, normal running and shutting down of your computer. Not all of them will apply to you but look through the list and run those that seem appropriate:

    1. Make sure you are free from malware as that can slow it down. If necessary, run your ‘anti’ programs.

    2. Insufficient memory (RAM) can slow the system down. A minimum of 2GB is recommended, more if your system can cope with it. Also, SuperFetch preloads into memory the programs and data it expects you to use based on past usage. This does result in quite a lot of disk activity after startup as files are read from disk into memory but it can make a difference to the launch times of frequently used programs where a large amount of RAM is installed. It can be slightly beneficial to disable it on systems with less than 2GB of RAM via the Windows Orb (Start) > All Programs > Administrative Tools > Services. Scroll down to Superfetch, double-click it and change the Startup type to Disabled and click Stop to immediately turn it off.

    3. Check the disk for errors. Open a Run window (Windows Logo key+R), type chkdsk /r and press Enter. Allow it to run next time you restart the computer or restart it now.

    4. Indexing takes a day or so to settle down on a new computer. The settings can be changed in Control Panel > All Control Panel Items > Indexing Options. However, if you don’t do much internal searching, turn it off completely via Control Panel > All Control Panel Items > Programs and Features > Turn Windows features on or off in the left pane > Indexing.

    5. Turn off Scheduled defragmentation via Windows Orb (Start) > All Programs > Accessories > System Tools > Disk Defragmentation. However, every so often you need to check if any disks have become excessively fragmented, which can affect disk performance.

    6. Don’t turn off your antivirus program, but check if it’s running a scheduled scan when you switch on the computer. If it is, reschedule it for a more appropriate time.

    7. You’ll get a slightly faster start up if you optimise the boot files and applications by running a special defragmentation (not on an SSD) from an elevated CMD prompt, i.e. click the Windows Orb (Start) > All Programs > Accessories and right-click Command Prompt, then ‘Run as Administrator’. Type defrag C:\ -b (note the two spaces) and press Enter. Depending upon your computer specification, it shouldn’t take more than 10 minutes to run.

    8. When you have a slow boot, check that no external drives have media in them. If they have, experiment by booting with it inserted and without.

    9. Remove unwanted programs that run when you switch on the computer. Bear in mind that it’s not necessarily how many programs run at start up, but which of them affect the computer’s performance. If possible, look at the program’s options/preferences to see if it can be stopped from running at start up.

    If there is no option, run Microsoft’s Autoruns from here http://technet.microsoft.com/en-us/sysinternals/bb963902 Go to the Logon Tab and remove the tick alongside the programs you don’t want to start. Right-click an entry and choose Search online for more information about it. It is completely reversible if you unintentionally stop a program from starting up. Right-clicking also contains a Delete option.

    Also, the built-in system configuration utility (msconfig) can be used, but its primary function is to troubleshoot start up errors. Note that some programs use a service to start them running.

    10. To check if a particular program is slowing the machine when you switch on or shut down, e.g. an antivirus program, go to Control Panel > All Control Panel Items > Performance Information and Tools > Advanced Tools (in the left pane). The problem is sometimes shown on this screen, although you may have to click View performance details in the Event log and follow up any errors marked in red. If the problem isn’t shown, click the Windows Orb (Start) > All Programs > Accessories, right-click Command Prompt then ‘Run as Administrator’. Copy and paste or type wevtutil qe Microsoft-Windows-Diagnostics-Performance/Operational /f:text > %userprofile%\Desktop\Event.txt (note the five spaces) and press Enter. If you Copy and Paste the command, use mouse right-click to paste it into the prompt. Close the Command Prompt and double-click Event.txt on the Desktop to open it. Go to the end of the file (Ctrl+End) to see the most recent events. Those with an Event ID in the 100 series are start up events and those in the 200 series are shut down events. There may be a name or reason in the event listing.

    11. Although hard disk errors are rare, they can slow up the machine, so its worth spending a bit of time checking. Click Computer > right-click the hard disk drive that you want to check, click Properties > Tools Tab and then, under Error-checking, click Check Now.

    12. To see which tasks are running, open a Run window (Windows Logo key+R), type cmd /k tasklist /svc (note the three spaces) and press Enter. Close the Command Prompt when you have finished viewing it. To get a better description of the associated Service(s), go to Task Manager (Ctrl+Shift+Esc) > Processes Tab and on a specific Svchost, right-click it > Go to Service(s) to see all the Services, which are highlighted.

    Alternatively, use Process Explorer to see which services/programs are using which files. To determine which process is using a particular file, click Find at the top, type the name of the file and click Search. To see the svchost processes, let the mouse pointer hover over each svchost.exe in the left pane. Download it from here http://technet.microsoft.com/en-gb/sysinternals/bb896653.aspx

  • Hi,

    Please check if there is any abnormal symptom in Task manager.

    Try the following methods to improve the performance:

    1. Run Disk Cleanup.

    2. Run performance troubleshooter: Control Panel\All Control Panel Items\Troubleshooting\view all\Performance

    3. Install the latest updates to keep machine up-to-date.

    More details refer to: Optimize Windows for better performance

    Best regards,
