Windows 7 Service Pack 1 made my computer slow down

Use Ctrl+Shift+Esc rather than Ctrl+Alt+Del to bring up Task Manager. In Windows 7 it simpler and quicker.

Event Viewer Reports

1. Normally when an error occurs on your computer looking in Event Viewer should be your starting point for finding a solution. Most system related errors are logged and getting an exact copy of the relevant report is important. Unfortunately understanding the reports is not easy and most computer users need help with their interpretation. I have more to say later on interpretation.
2. Event Viewer comprises three main Windows logs. These are Application, Security and System. For troubleshooting purposes System is by far the most important.
3. To access the System log select Start, Control Panel, Administrative Tools, Event Viewer, from the list in the left side of the window select Windows Logs and System. Place the cursor on System, right click and select Filter Current Log. Check the box before Error and click on OK and you see only Error reports. Click on the Date and Time Column Header to sort. You may need to click a second time to see the latest Report at the top.
4. A tip for posting copies of Error Reports! Run Event Viewer and double click on the error you want to copy. Click on the Copy button to place a copy on your Clipboard and close Event Viewer. Now start your message and paste into the body of the message. Make sure this is the first paste after exiting from Event Viewer.
5. There are three types of Report, being Information, Warning and Error reports. In most situations it is Error Reports that offer the best information but occasionally Warning Reports provide useful clues.
6. All reports have date and time stamps and when troubleshooting it is important to concentrate on more recent reports. Study reports since the point when the computer was last booted and then check whether a similar report appeared in the previous session. If errors do not repeat investigation as to why they occurred is wasted effort.
7. Within individual reports the more important information is Event ID and Source as these help when looking for help on the internet. The description is equally important and copying the exact text for use as the search criteria greatly helps getting better results when using Google. Do not paraphrase descriptions when asking others for help.

Same issue with me. I updated to SP1 and the results have been disastrous:

-First, my internet suddenly stopped working, wired and wireless. After a couple of reboots, it magically started working again.

-Then, my computer just started slowing down. Every time I clicked on a program, it would take much longer to load. Deleting something would take longer to delete. Everything was at a crawl. My web pages took longer. No virus, malware, etc. My computer was clean. But wait, it gets worse With my PC running like **** yesterday, it suddenly froze. I tried hiting the ALT+CTRL+DLT to bring up task manager and it gave me an error message. The computer froze so I was forced to reboot. Now it won't even boot. I had to use start-up repair yesterday that took 2 hours with NOTHING. I didn't want to leave it on all night so I shut it off. I turned it back on this morning and I'm praying it fixes the issue by the time I get home from work. But reading around, it looks like either my hard drive is done, or I will have to do a reinstall and lose all of my saved data. Regardless, I'm done. I have one more resort which is to use a windows repair disc but i read even that doesn't work. Seems lie star-up repair is something you DO NOT want to see. I tried booting in safe mode, last good configuration, etc. Nothing.

But still, this is flat out disgusting and unacceptable. I am completely at a loss of words.

Hi Cookie7746... Why so much anger against another user? I run Avast, Spy Bot Search Destroy, CCleaner, Auslogic Disk Defrag. at least once a week. I keep my computer very clean, light and nimble; and guess what.... after installing SP1 for window's 7 my performance also went to ****. So these people have a valid reason to be upset. Frankly so I'm I. I have a high octane computer, Sony VAIO Core DUO P8600 @ 2.4 processor, 4 Gigs of RAM. This is not to shavvy. There is absolutely no reason why after I clean my computer once a week with the programs listed above that my computer should freeze with programs that I would run flawlessly before. Quite simple Microsoft dropped the ball on this one... You know guys I was debating whether to max out my RAM to 8 Gigs and keep my PC for another to years or make the switch to the dark side and buy a Mac Book Pro.... Thank you Microsoft for helping me make my decision...
