    Windows 8 very slow after update


    I did the update issued the other day (four reboots when it took one with Windows 7) and now the system is incredibly lethargic. Log on is as slow as a wet week and every application seems to almost hang before they start up. Even shutting down takes at least three times longer than with Windows 7. I've also lost colour management on my dual screen setup, even though I've manually re-selected the calibration files that worked previously.

    I was pretty impressed with Windows 8 and looking at transitioning fully to Windows 8, but this latest setback has made me doubtful about its integrity. So I'm now back to using Windows 7 (mine is a dual boot), as it's working fine and much faster. What on earth is going on here?

    I'd try to uninstall the recent updates or to run a restore of it.

    That's an option, but I was wondering whether anyone else has experienced a similar issue. There were 44 updates for Office 2010 and Windows combined, so I'm loathe to go through and delete them all.

    Yes, they broke perfectly working installation, unfortunately, I had to do a clean install.

    I did some Googling and it appears I'm not alone, as others are experiencing the same issues. Not a good look for Microsoft after such a short time out. It'll give those who said Windows 8 will be another Vista simply more ammunition. I think I'll just leave things as they are for the moment and see if anything comes out in the next week or so to address the problems.

    Your type of hardware, is one parameter that you must take into consideration before installing Windows 8. Does your system support Windows 8 or/and does it meet the minimum requirements?

    Out of curiosity, what does task manager to show your disk usage to be at when these hangs occur? Or even on idle?

    Mine's a low spec x64 PC with an i7 920 2.67GHz processor, 8 GB RAM and Radeon HD4800 graphic card and a few other bits.

    I had another look at the updates and discovered that none of them had succeeded. When I did the updates, I just left the system running and came back every so often to log in for a restart. It seems that Microsoft decided that the system would try to install the updates multiple times before giving up and that's the reason for the original number of restarts. I found this out after trying to reinstall the updates while watching the entire process and seeing it go through multiple attempts (stupid idea).

    Remembering an issue I had with a very big Windows 7 update, that also failed on the initial attempt, I decided to do the same thing that achieved success ie, install the updates individually. The largest update was around 170MB and this succeeded, so did the next largest at about 150MB and when I went to do the next one, instead of there being nine updates remaining, there was only one left, KB2770917 at about 170MB. This was strange, but I started the install and it promptly failed. Clearly this one was an issue. What I don't understand is why the original failure did not appear as an alert, as it would with Windows 7.

    Windows 8 is still slow, despite the two successful updates, so something is clearly amiss with the updates.

    I might also add that the updates applied to my Gigabyte S1080 (x32) have not affected speed and the tablet is running fine, much faster than my PC in both desktop and tiled interface. So it's only affecting my x64 system.

    An interesting update. I had another look at Windows Update and three new updates popped up, a 1.9MB, 165MB and the KB2770917 again. So I installed the 1.9MB update and all went well, but when I went back to consider the 165MB update, it had disappeared and a 50MB version of KB2770917 had appeared.

    OK, thought I, I'll install that and see what happens. Surprisingly, it installed without issue. So once again I had another look in Windows Update and this time another KB2770917 had appeared, but this time around 90MB. OK, try again, but this time the install failed and I had to go through two install attempts before I was finally able to log in.

    One has to wonder what on earth is going on here, with failing updates, constantly changing updates, the same updates changing etc. Is Microsoft just doing things on the run, without a real clue as to what they are doing? And everything is still slower than on Windows 7.
