    Desktop slow and unresponsive all of the sudden

    I have installed the Anniversary update and 2 updates since then and all of the sudden my desktop is slow and unresponsive. Icons on the task bar do not highlight when the cursor passes over them. If you let the cursor sit on an icon for a while it may highlight. Any dialog boxes that pop up are blank and you have to wait quite a while for them to populate with text and buttons. When you hover over an icon on the desktop the cursor does change to a hand but the text of the icon does not underline like it did in the past. Left click context menus pop up right away but when you move the cursor to select an item the menu item does not highlight, however you can click it and it does function. I have installed the latest Nvidia drivers (and went into safe mode and uninstalled the old driver completely with a driver cleaner) to no avail. I try rebooting explorer from the task manager but to no avail. Rebooting sometimes helps (most often not) but the system can work OK for hours after a reboot and then...boom it becomes unresponsive. Any ideas?

  2. New Computer all of the sudden running SLOW !!!!!!!!!


    Try the Clean Boot method to see if a startup program is involved - if so it is a

    process of elimination :

    Right Click the start button - Command Prompt (Admin) - at the prompt type in


    and hit enter

    How to perform a clean boot in Windows - Windows 10 is essentially the same


    Do all of these :

    If you had a 3rd party antivirus on the OS you upgraded OR if you have one

    now uninstall it and then run its maker's removal tool. Use Windows Defender

    which in Windows 8/8.1/10 is a full antivirus. Despite all the hype out there

    Windows Defender and the Windows Firewall are true superstars.

    List of anti-malware program cleanup/uninstall tools

    List of anti-malware product removal tools

    Uninstallers (removal tools) for common antivirus software

    Uninstallers (removal tools) for common Windows antivirus software


    Check this :

    Right Click Start button - Control Panel - Troubleshooting - on right side click View all -

    System Maintenance.


    Windows Key + X - Command Prompt (Admin)

    SFC /scannow

    Note if that shows uncorrected errors - do the below regardless.

    When that completes run these :

    DISM /online /cleanup-image /scanhealth

    DISM /online /cleanup-image /restorehealth

    Note if that shows any uncorrected errors - do the below regardless.

    Then restart the computer.

    Be sure you are running the latest available BIOS and drivers.

    Check with System Maker (Motherboard Maker for custom systems) for updates

    to the BIOS, low level chipset drivers, and the major on-board and separate

    drivers. Run DriverView - set VIEW to Hide Microsoft drivers - update

    those without Dump in their name.

    DriverView - Free - utility displays the list of all device drivers currently loaded

    on your system. 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.

    DriverView: Loaded Windows Drivers List

    For Drivers check System Maker as fallbacks and Device Maker's which are the

    most current. 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. Now click UPdate Driver (this may not do

    anything as MS is far behind certifying drivers) - then Right Click - Uninstall -

    REBOOT this will refresh the driver stack.

    Repeat that for Network - Network Card (NIC), Wifi, Sound, Mouse and Keyboard

    if 3rd party with their own software and drivers and any other major device drivers

    you have.

    Now go to System Maker's site (Dell, HP, Toshiba as examples) (as rollback) and

    then Device Maker's site (Realtek, Intel, Nvidia, ATI as examples) and get their

    latest versions. (Look for BIOS, Chipset, and software updates at System Maker's

    site while there.)

    Download - SAVE - go to where you put them - Right Click - RUN AD ADMIN -

    REBOOT after each installation.

    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.

    Repeat at Device Makers - BTW at Device Makers DO NOT RUN THEIR SCANNER -

    heck manually by model.

    Manually look at manufacturer's sites for drivers - and Device Maker's sites.

    How to Find and Download Drivers

    Hope this helps.

    Desktop slow and unresponsive all of the sudden

    I had the same problem, tried in-place repair but still the same, tried several times which eventually it became even slower, I recovered via an image & problem resolved. I have noticed since that Windows Defefender limited periodic scanning slowed my PC down & turning it off speeded it back to normal.
