    I tried to refresh my windows but I get an error saying drive where windows is installed is locked, unlock drive and try again. I tried going in cmd drive attributes and removing readonly but get error drive attributes failed to run.

    I have run all above mentioned fixes, but the problem still exists. when I try to refresh windows I get drive where windows is located is locked, please unlock and try again. I've tried running the disk attribute clear readonly command but get message disk attribute is not completed.

    Ok friend, instead of trying these random copy+paste command which really wouldn't effect such a problem in the first place, let's actually get to the bottom of just what is going wrong, and fix that. No refresh needed... hopefully.


    Download Process Hacker 2: http://processhacker.googlecode.com/files/processhacker-2.33-setup.exe

    Install it, launch it as administrator. To be sure its running fully elevated, focus the window and go to File -> Show All Processes.

    If the show all processes isn't there, its fully elevated.

    Now switch to the Disk tab and re-sort everything by maximum read or write the same way you would re-sort a list of files alphabetically.

    You should hopefully see the offending process. Double click the process and switch to the threads tab.

    Look for a thread that has a really high number next to it, and post the name here. Along with the process name, and if possible a screenshot of the ProcessHacker window.


    If nothing showed up in the Disk tab or you couldn't get as far as I said above. Let me know, we'll try something else.


    If I don't come back for whatever reason, go ahead and attempt to terminate that thread, and if your computer doesn't BSoD (should be safe if you close all work and save anything before attempting to terminate it) than you know what exactly you should uninstall/delete to free yourself from the problem.

    Be warned though, process hacker 2 is a powerful tool, and its misuse can lead to needing to reinstall windows. So do be careful what you click on. It has addition confirmations in place, so be sure to read them before hitting OK.

    I had to go out of town and just now got back to this. I installed process hacker and this is the process that is the highest

    System (4), C:\Windows\System32\sru\SRUDB.dat, , 873.67 kB/s, 873.67 kB/s, Normal, 2

    when I double click it opens folder view and I don't see a thread tab
