    Windows 7 running quite slow on 2011 iMac

    Hi there,

    I have been working on a 2011 iMac which has Windows 7 installed on it.
    The iMac is very high spec, but I am surprised by how sluggish Windows 7 seems to run on it.

    I have ran a defrag, malware, spyware and av scan and nothing suspect. The Windows 7 OS is fully up to date with Windows Updates.

    It is run via BootCamp. Would it be worth me running any OSX updates? Would this help the Windows 7 partition in anyway? I am assuming not, but can't understand why it is not running to its full potential.

    Any ideas would be really appreciated!

    What HDD does the Mac have in it? We've got some that are high-spec but Apple put a 5400rpm hard drive in so boot times and general performance aren't great as a result.

    If you believe Paul Thurott apples drivers for windows are badly written which means poor performance. I'd go with a virtual machine.

    A good spec apple is generally a mediocre spec PC at best. I would agree that the drivers are probably not helping, just look at iTunes on a Windows box for how bad they can sabotage software. I'd also run any updates that may include firmware as that could also be partially to blame.

    I find that hard to believe. The bulk of the hardware inside a Mac is perfectly standard, i.e. the chipset, CPU, GPU, network controllers etc. They'd use the same drivers as they would on a "standard" Windows box.

    I'm inclined to agree with @gshaw, it's likely to be a 5400rpm HDD that's the problem. Assuming you have a 20" Mac anyway.

    Thanks everyone for your posts. It is a 27" iMac. Not sure on the specs, but I do have the serial no and have checked on one of the online spec websites, the following is shown:
    Thought the processor would be better, but hdd does not look all that bad.....

    That's the same model that I run at home, albeit with the equivalent quad core i5 rather than the dual core i3. It runs bootcamped Windows quite happily with no performance issues that I can see.

    It may be worth disabling some of the Apple background services and downloading the latest drivers for hardware from the hardware manufacturers? Mine has a Intel chipset, an Atheros wireless card, Broadcom NIC and an ATI graphics card.

    Mavericks is a good upgrade (subject to application compatibility) and is well worth doing. Presumably when OSX runs, it runs fast?

    Depending how old the Windows install is, you could also re-install Windows as new (if possible), or alternatively see if there's anything such as malware or anything else bringing it to a crawl.

    Like a native PC, Windows 7 works fine on Bootcamped Macs with 2GB+ of memory for most general tasks.

    I'd check Device Manager and Google the HDD model number just to make sure it is what the spec says before you spend time diagnosing anything else...

    Apple are usually quite good when it comes to hard drives. My iMac has a Western Digital Black drive in there, pretty much the best that was available at the time.

    I would re-install windows 7 with SP1 and ensure that the latest AHCI / chipset and other drivers are installed

    Some Education spec Macs seem to be built down to a price by putting 5400rpm drives in, certainly some Mac Minis we have are afflicted with that despite having fast i5 CPUs
