    Installing windows 10 on a Dell Inspiron 620

    Dell is not checking the Inspiron 620 for Windows 10 compatability and has no plans to update drivers. Has anybody successfully installed Windows 10 on a Dell Inspiron 620?

    There are millions of hardware combinations on the market, which people use. So I don't know if you'll get many answers if you ask that way.

    However, there are quite a number of Google hits on that question:
    "windows 10" "Dell Inspiron 620" - Google Search

    I found one user for whom the upgrade itself worked nicely, but he wrote that afterwards he had issues with the Intel HD 2000 card: Video playback was somehow problematic and also the sound did only work, if he connected and disconnected his headphones.
    The sound problem sounds like a setting problem to me; I think that should be solvable. For the HD 2000 graphics card, you should really use the newest drivers. For an Intel HD 3000 card I am using drivers from May 2015 and they work nicely. Older drivers may have problems under WIndows 10. So check, if there are new drivers for the HD 2000 and if so, install them.
    The user with the graphics/problems found these issues to be too bad for him.

    Whatever you do: Before you start the upgade, make sure that you have a system image of your Windows 7 installation. From the user with the graphics/sound problems:

    After a couple of unproductive hours I restored the machine back to windows seven. This did not come without problems though, the factory installed OS image has been removed and all system scheduled tasks have been corrupted. It has taken a few days to get the machine running ok but restoring the system tasks is complex and the best way to fix this and I assume the recovery image will be a full restore using the system back up discs I made when the machine was new. I have tried asking Dell the question but they do not seem interested(...).

    Hi. I know this was an old thread but I have successfully upgraded my family's Dell Inspiron 620 desktop computer from Win7 SP1 to Win10 v1511 in early August 2016, using the Win10 DVD installation media I created months before the July 29, 2016 deadline - and Win10 v1511 automatically activated free after I installed the WLAN drivers for the Dell DW1525 wireless adapter & enabled the WiFi internet connection there. I did NOT upgrade to the v1607 anniversary update edition of Windows 10.

    Before upgrading to Windows 10 on the Dell Inspiron 620 PC, be sure to update the BIOS first to revision A10 from here:

    And Microsoft has released updated Intel HD Graphics 2000/3000 drivers (v9.17.10.4459 dated 5/19/2016) for Windows 10 on Microsoft Update Catalog. These were published around the time Win10 v1607 came out but they can work for older builds of Win10 as I just tried them out myself.
