Installing Windows 7 Service Pack 1 Slows The Computer | How To Fix

This article will let you fix to slow performance of Windows System after the Installation of Service Pack 1.

One of my fried has mailed me that his Windows 7 (HP dv6-1253cl) Pc started to perform too slow once he installed Windows 7 Service Pack 1 from Microsoft. And all his programs in his Windows 7 machine takes longer to start up, compared to the day before installing Windows 7 Service Pack.

But does Windows 7 Service Pack slows down the PC?  Actually, Windows 7 Service pack and other Windows Updates are released to improve the performance, reliability and security of the system.

If your system is slowing down means, there could be several causes why you are experiencing performance issue on your computer.

If you have installed any additional software after the installation of Windows 7 Service Pack 1, that can also be a problem, or there can be some conflict between the drivers and may be even with other software's that are already installed.

Well, do not try uninstalling the Service Pack 1, doing that will not remove all the updates related to Service Pack 1. Tons of updates wont be removed.

You may need to perform a System Restore to completely get back to the situation where Service Pack has not been installed. And to do so,

  • 1. Type “System Restore” on start menu search.

However, the above step will take you to the positon before installing Service Pack 1 for Windows 7. However, we cant be sure that the same problem wont arrise when you install the Windows Update Again. So, the best idea is to troubleshoot the exact problem. And To troubleshoot and solve this issue try the following steps:

Method 1: Run the performance troubleshooter and then check

Open the Performance troubleshooter


Method 2:  If a Windows Resource Protection (WRP) file is missing or is corrupted, Windows may not behave as expected.Run System File Checker (SFC) scan to fix any corrupt system files. To do this, follow the steps mentioned in the link below:

How to use the System File Checker tool to troubleshoot missing or corrupted system files on Windows Vista or on Windows 7


Method 3: Put the computer in clean boot and then check to see if the issue persists

Follow  Step 1 in the link below,
How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

If everything works fine after a clean boot, you can infer that some third party services are causing the problem.

Proceed with the remaining steps to pin-point out the third party service.

After you figure out the problem causing program, you may have to update or install a higher version of the program, if you seldom use that software you can consider uninstalling it.

Remember to put the computer back to normal startup follow   step 7 in the link.

If this method has not helped you, then you can go for a system restore, and check if you have all the latest driver for all your hardware and try to install the Service Pack in a few days time.

The only difference is that you're suggesting that we go back to the restore point before the slow down. Everything else you said is just as ridiculous as the microsoft answer, because it is the microsoft answer and doesn't work.

Thank you for visiting bench3. It will be ridiculous If I ask you to reinstall your Operating system. Buy the way, Restoring is the only possible solution when nothing works for you. That is what i have suggested here. Or, i f you have a better solution, you can post that as a comment here.
