    Should I re-format my disk?


    Should I re-format my Windows 10 disk SSD?
    Or is there a something similar I can do to clean out my registry?

    I have a fairly new PC with lots of free diskspace and 16GB of DDR4 3000MHz Memory. Here's what happened:

    1. MS Office 365 (Business) became extremely slow to open (15-30 seconds to open Excel).
    2. So I called MS Support. After about 3 hours of re-installing Office there was no improvement.
    3. Eventually they talked me into creating a new Windows profile.
    4. This now opens Excel fast. But there is a new problem: I am completely unable to change the default program for editing .TXT files.

    Also the wheel on my wheel mouse no longer works.

    Given that every single setting I have within windows, including every setting for every application, now needs to be re-configured it feels like I might as well re-install windows. Given that Windows always seems to get slower and slower over time, (due presumably to the registry getting more and more bloated) should I actually format my entire hard disk?

    Or is there some other way to "Refresh" windows without actually losing all my applications? And if so would that be just as effective at cleaning up my registry and speeding up my PC?

    Hi, sorry to hear of your problems. That's not my experience (above) - I clean installed Win 10 on this on its first public release, and have upgraded since then- but only to 1709 (by choice). I have LOTS of programs installed.

    No, the registry is not the cause of Windows becoming slower.

    You can
    a. check your disk
    b. check your file system
    c. do an in-place upgrade repair install which keeps all programs, data and most settings.

    This won't clean your registry (and please don't use tools to do so).
    I am completely unable to change the default program for editing .TXT files.
    I'm going to guess your Windows build is 1803, and you have update KB4462919 installed. This causes this problem.

    1. First check your disk(s):
    Download and run Hard Disk Sentinel (trial) (includes SSDs)
    (This gives exceptionally good text comments)
    Post a screenshot of its GUI using the Insert Image icon above your post.
    If all disks are reported as good, continue.

    2. Now check your file system:

    From an admin command or powershell prompt
    [Windows key + X, click command prompt (admin)]
    chkdsk C: /F
    Your PC will need to restart.
    Post back the result, which you can get after a restart as follows:

    - this includes a link from which you can obtain a Windows 10 iso file (" download a Windows 10 ISO"), or create a Win 10 bootable medium. However, this will be the latest build from MS, which may not be the build you have installed. You must use one for the same major build.

    ** Do this without accepting updates - you can do it with the internet disconnected.

    After that you should hide the update mentioned above (Tutorial in the Tutorial section available).

    OK, HDSentinel say my hard disk performance is "100% excellent" and my health is "99% excellent"

    I shall now run checkdisk, but it requires a reboot. More shortly...

    OK I have now run checkdisk. Unfortunately when I click "Event Sources" within Event Viewer, there is no drop-downlist of any sort.

    Is this what you are looking for?

    Note: if you were to uninstall that update your association problem will probably be resolved. But that's not your only problem of course.

    Anyway, you could try that and see which other problems remain and decide what to do then.

    I would think your mouse problem is a separate issue- either hardware (could it simply be full of fluff? Have you ever cleaned it out inside?) - or a driver problem.

    I have uninstalled and "hidden" the KB4462919 update. But still I had great difficulty in getting TextPad to open .TXT files. I have now done so, (through uninstalling in a different windows user profile) but I am concerned that the windows system itself is now starting to creak.

    The state of play is that if I go to my original user profile (in windows) then MS Excel takes up to 30 seconds to open, whereas if I log into my new user profile in windows then Excel opens very fast (e.g. in 3 seconds). Microsoft Office support seem to be completely unable to resolve this issue.

    Note that 2 people have reported hiding KB4462919 didn't work for them. That's assuming they did it correctly- but could that be yet another possible MS problem?

    Battles with associations in 1803 seem relatively common- a new phenomenon compared to previous builds. You may just have to compromise for now, or try using Filetypesman (free) and the registry editor as necessary to do it manually.

    Have you tried an in-place upgrade repair? (see above).

    if I log into my new user profile in windows then Excel opens very fast (e.g. in 3 seconds).
    The clue here is that there is a difference between the two profiles.
    Examine carefully
    - what is running in one vs the other e.g. by comparing a list from task manager, Details created in 1 profile with the other.
    - resource usage - is your RAM full in the profile when it is slow? - is there excessive disk actvity?

    Have your task manager open, then launch Excel in the problem profile. Note any excessive resource use, and compare with the other profile.

    Office startup: other possible diagnostic steps:
    a. Check in Safe Mode for reference
    b. Compare after a clean boot (if you don't know how see the tutorial here or Google 'What is a clean boot')
    If faster, progressively enable items to discover what is conflicting.
    c. Use Windows performance recorder (MS tool) to diagnose what's actually happening.
    (Search this site for 'Windows performance recorder' for examples of threads where this is used).
    - somewhat technical
    d. Use Process Monitor (MS tool, sysinternals) to capture all activity to see what happens when you launch Excel.
    Technically daunting- massive log.
    e. Use Autoruns (free) to disable more startup items to discover what may be slowing Excel
    Novices find this tool disconcerting. Simply tick to disable items. They are usefully grouped in categories.

    Before making changes for test purposes, make appropriate backups. Don't just rely on System Restore as restoring is widely found to be unreliable (it either works or fails completely).

    OK I was utterly confused by the link describing how to do an "In place Upgrade Repair". (I thought it was asking me to do a Refresh.) OK I am now running an In Place Upgrade Repair, using a USB flash drive and without letting it download updates.

    [Out of interest, technically what is actually happening when one does this? Are all core Windows files being over-written? Is anything happening to my Window Registry file? ==> Might any of this help with my original problem of MS Office being slow to open?]

    Once I've done so, I guess I'll need to try to work out out to hide the KB4662919 update.

    It's just like upgrading, but going back to an earlier version of the same build. So you get Windows.old created, perhaps a new recovery partition. System Restore points are of course lost (as they should be). The default state of services is re-established...etc.

    Hide update:
    Windows update minitool (free) has a hide option, or the tutorial.

    OK I managed to hide the KB4662919 update using "wushowhide.diagcab"

    What is deeply irritating is that even after you have managed to "hide" the update, Windows tried to download it!! I *think* that I managed to stop it from installing.

    Either way "wushowhide.diagcab" sayst that I have successfully hidden the KB4461919 update. It says that the update failed to install at the last update.

    Note 2 users report they tried to hide that update but it still installed..
