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.

I have two identical HP dv-7 quad-core laptops and since Windows 7 service pack 1... they now suck in a very big way. The systems have come to a crawl in speed, they lag at every click of every program, internet response times are a joke... this sucks. It is like running an eight cylinder car on one cylinder now...

This needs to be fixed without me having to re-image!

I encountered the same problem. I have my system set up to dual boot Ubuntu, so I checked the system diagnostics there. It reports the hard drive has had over 42,000,000 bad sector reads. The problem started with the next boot after installing SP1, an ATI video driver update, and KB2488113. Strangely, the HD passes all the diagnostics I am able to run on it.

It may be a concidence that the problem started with the SP1 update, but I suspect Microsoft has screwed something up in the low level drive interface. It is helpful to know that others are having the same problem.

Hi all,

I am also an IT manager, and I manage between 6 and 8 networks of varying sizes. Our updates are all controlled by WSUS and a test group was setup on each LAN (we use groups of 2 machines per LAN because machine are standardised). Some worked fine and others slowed to a crawl where the machines were unable to open 60kb Word documents while other networks are perfectly fine.

Even if I use a downloaded copy of SP1 which I have installed on my home machines with marginal slow-down, the machines on the LANs that were affected are so slow it quite literally takes 15 minutes for a user profile to log in. All the back-end servers are completely up to date and it seems to only be Server 2003 based networks that are affected.

The update can be removed under Programs and features from the windows updates list and takes roughly 15 minutes to complete per machine, returning the PC to a condition where it flies again.

The inconsistency it what surprises me. My own office network is 2003 based and there are no issues with it, yet almost all of our clients have this problem, resulting in the SP1 download in WSUS being declined.
