Fixing Windows 7 Service Pack 1 Installation Problems

Is your PC or laptop running Windows? If so, you have probably run into problems while running Windows Updates. Microsoft releases a large update to Windows occasionally, called a “Service Pack,” or SP. These service packs are numbered in the order they are released.

For Windows 7, the current release is Service Pack 1, or SP1. This service pack has many updates bundled inside. If any one of these individual updates fail, the entire install of SP1 will fail too.

These failures happen for many different reasons, including:

  • Running out of space on your hard drive
  • Turning off your computer while it is in the middle of an update
  • Installed software that conflicts with one of the updates
  • Viruses or malware on your computer
  • Corruption in the Windows system files
  • Corruption in the Windows registry — the registry is a database where Windows stores much of its configuration

There are steps you can take if your computer won’t install SP1. These steps don’t require expertise in computers, and may solve your problem:

Solution 1 – run the Disk Cleanup Wizard

If your computer is almost out of space, the service pack 1 install may fail without telling you why. Running the Disk Cleanup Wizard can free up space without deleting your personal files and allow the install to succeed.

  1. Press the Windows Key
  2. Click Control Panel

  4. Click Open disk cleanup
  5. Click OK
  6. In the results window, click OK

Solution 2 – Run the Windows tool for fixing windows update problems

Microsoft provides many tools and utilities for fixing various issues. This one is specific to the Windows Update components and will repair any obvious problems.

  1. Press the Windows Key
  2. Click Control Panel

Solution 3 – Download and install SP1 from Microsoft manually

First, you need to determine if you are running 32-bit or 64-bit Windows. This will determine which file you download for the SP1 install.

  1. Press the Windows Key
  2. Click Control Panel
  3. Click System
  4. From the center of this window you can see if you are running Windows in 32-bit or 64-bit.

  6. Click Download

  7. Scroll to the bottom of the file list.
  8. If you are running 32-bit, check the box next to windows6.1-KB976932-X86.exe.
  9. If you are running 64-bit, check the box next to windows6.1-KB976932-X64.exe.
  10. Click Next. The file will then download.
  11. Double click the downloaded file to install SP1.
  12. Follow the directions to complete the installation.

Solution 4 – Check and repair damaged system files

If your computer is showing other signs of performing poorly, or simply showing errors in the form of crashes or pop ups from Microsoft, you might have some damaged system files. To repair these, Microsoft also provides a tool called SFC, that you must run from a command window. Learn about running SFC here.

Hopefully one of these solutions fixes the problem and that your Service Pack 1 will install correctly. If not, leave comments below and we will help you fix it!

    Windows update refuses to install Service Pack 1 to my
    Windows 7 Home configuration

    I downloaded & ran SP1 manually but it told me
    sqmapi.dll was missing so I found a tool to reinstate that file and ran the SP1
    installation again it failed.

    So I ran it again with Norton turned off – failed.

    I ran a complete virus scan – failed.

    So I ran sfc scan now – no problems found.

    Ran the system update readiness tool – no problems.

    Ran the windows update tool for windows update problems –

    Ran the installation again – failed – message Error_sxs_assembly_not_found

    Now I’m thinking maybe I should give up and hope that not
    installing SP1 will not give me any problems.
    HELP! Norman.

    Hi Norman

    I have identical problem except your final failed message.

    I only got the message sqmspi.dll when I attempted to install SP1 manually.. I installed it from another Win 7 machine and registered it.

    Only other difference may be I am running Ultimate, not Pro on problem machine.

    In the Event Log I see:

    Installation Failure: Windows failed to install the following update with error 0x800f0816: Windows 7 Service Pack 1 (KB976932).

    In some games , for example Need For Speed World , when you launch a game , it says that has some problems with SP2 , Then i go to Control Panel , Look if there’s any SP2 , Honesty i find that it’s only SP1 and SP Microsoft normaly . So what should i do? Should i take the same steps of the 2nd Solution or?
    Thank You.

    Followed all above suggestions and not fixing the problem..

    2) problem prevents trouble shooter from starting….error..ox8E5E0247..

    3) catastrophic failure…error..ox8000ffff..downloaded OK but would not install..

    4) Windows Update Standalone Installer ..System Update Readiness tool..error..oxc8000247

    I have W 7 64 bit..home premium ..
    And a couple months ago I replaced my old HD and used my rescue disc to reinstall W7 and the same problem followed to the new HD.
    How can this problem present its self exactly even after a reinstalled OS ?
    Windows update does not work…
    Tried to install NET.Framework 4.6.1…not supported on my system ??

    Ran sgf/scannow..said I had corrupt files that they could not fix.

    Nothing works..

    Hello, I had problems installing Sp1 in Windows 7 – 32 bits. After trying several options, I realized my hard drive was damaged. I add this comments just for you to take this in consideration before trying several things.

  • Adam Person

    I have been at this problem for 2 weeks now. Nothing peculiar about the install (new Win 7 64 bit disk for install with fresh serial number). I have done all the fixes that everyone suggests (THANK YOU TO ALL FOR YOUR TIME) with no solution.
    Is it possible that Microsoft has a hand in this? Just maybe they’re really pushing Windows 7 out the door by not allowing this update to complete so people will be forced to go to the CRAPPIER Windows 10. I mean, this is all their software and code, we just rent it. I know nothing about how computer code works, all I know is that everything comes from Microsoft over the internet to me. This company called Microsoft is a joke. Enough of my time has been wasted, BYE BYE Windows, HELLO Apple. Anybody wanna buy a 1 year old Toshiba laptop?
