Windows 7 Service Pack 1 made my computer slow down

Anonymous

Yesterday I was dumb enough to install Windows 7 Service Pack 1 in my HP dv6-1253cl laptop and now all programs in my laptop take longer to start up, compared to the day before yesterday. I've installed no additional software or hardware in the meantime. The only difference is the Service Pack. My main program, Call of Duty World at War now takes FIVE times as long to start and also between screens. Response is now also lagging and all programs now freeze for about 30 to 45 seconds before they respond again.

I've tried uninstalling the Service Pack 1, but inexplicably there remain a ton of updates that weren't removed.

Doesn't Microsoft check the quality of the patches they release? What can i do now to regain the performance i had only two days ago?

Hi daffy688's,

Windows 7 Service pack and other Windows Updates are released to improve the performance, reliability and security of the system, there could be several causes why you are experiencing performance issue on your computer.

I would like to clarify if you have uninstalled or removed Service Pack 1 from your computer.

You may try the following steps:

Method 1: Run the performance troubleshooter and then check

Open the Performance troubleshooter

http://windows.microsoft.com/en-US/windows7/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

http://support.microsoft.com/kb/929833

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.

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

I too had the same problem. Quad Core Desktop, 4 gig Ram, 500 gig HD 2/3 empty...I defrag 2 x a week and run AV and don't go on any websites or have torrent or any of that stuff. My machine is clean for business only.

My machine was running pretty fast until I installed SP1 for Windows 7, 64 Bit last weekend (FEb 25, 2011).

Now it is SLOW booting, it takes 2-3 minutes, and programs are extremely slow to respond.

Can you make any suggestions outside of reimaging my entire system that would clean this up?

I don't want to have to get on phone support for MS Office Small Business and argue that I am reimaging my system and they should let me reinstall my 1 license. I had to put up with this recently...and I was very upset.

Best Regards,

ScottKG.

4 or 9 ???

OR 4 of 9?

I would always clear all other updates before embarking on a major download and install!

Here are some notes that may help resolve problems encountered when installing Windows Updates.

The process of installing updates comprises downloading, installing and configuring the operating system to use the new updates. Some updates require the computer to be restarted and when this occurs configuring occurs as the system is shut down and is completed when the computer is restarted. It is important not to interrupt the configuration process as configuration involves making changes to the registry. If interrupted, the result can be a computer that will not boot.

A lot of problems arise from setting Windows Update to automatically update. You may prefer to change this setting. Select Start, All Programs, Windows Update, Change Settings. Under Important Updates is a box showing the current setting. Click on the Arrow down to the right and change the selection to “Check for Updates but let me choose whether to download and install them” and click on OK.

If you encounter problems updating or you are not using the Automatic Update you should manually update by selecting Start, All Programs, Windows Update, Check for Updates. Check the boxes before the updates you want to install, click on Install and click again on Install in the next window and the process of installing starts. You should let the process proceed without interruption. Multi-tasking at the time updating is in progress is unwise. The progress window will tell you what is going on. You need to be patient.

If you have a number of updates to install break the task of updating into two or more tasks. If you have been having problems with Windows Update run Disk CleanUp (or better still cCleaner) and Disk Defragmenter ( or better still Defraggler) before installing any large download.

If the measures above fail to resolve your problem select Start, All Programs, View Update History and post the Failure Code and Update reference number to the Windows Update Forum at Microsoft Answers.

Do you want to say with this the major updates are encountering problems with the previous updates or the user is stupid becouse he doesn't read the instructions of the update where this clearly specified or both?

I thought the Windows is a very robust operating system where installing a "large" program is piece of cake. Maybe that's why I'm now stupid?

I also had the same problem after SP1 was installed! I’m using a smaller computer, an Acer R3610, as a multimedia computer to play music, movies ‘n stuff. It never was that good with playing movies. They lagged. It was until recently that I reinstalled Windows 7 to see if the speed might improve. To my amusement it did. Movies were played with ease. No lagging or nothing and even if it was .mkv files with 720p or 1080p. Finally I thought! But then I sat on Windows updates to the last. When I eagerly sat down to watch a movie it fcn lagged! I tried everything with codecs and cleaning up system files, but no. Nothing helped. Then I read here that SP 1 really makes computers slow. It’s good to know that it wasn’t something wrong with my computer, but something wrong with Microsoft’s programming. It’s really irritating that I had to reinstall Windows 7 again, and also reinstall Windows 7 on all my other computers. Now SP1 is a hidden update on my part.
