Is it possible to safely downgrade a Windows XP Service Pack 2 back down to a Service Pack 1?
If so, how would I do this, and does it involve re-formatting? I dont want to go through that, I just want to switch the SP because SP 2 is making this computer use a ton of resources.

Thanks

Start with this, if no change, a good way of removing SP2 is with a repair install

If you use add and remove you will get a lot of messages about programmes not running properly if you remove SP2

Items in blue which are underlined are clickable to give more information about the process

Click start then run, type prefetch then press enter, click edit then select all, right click any file then click delete, confirm delete

Click start, all programmes, accessories, system tools to run disc clean up, then from system tools, run disc defragmenter.

Click start then run, type sfc /scannow then press enter, you need the XP CD and Windows File Protection will show a blue onscreen progress bar, when the bar goes, reboot

If you do not have an XP CD you can borrow a same version as was originally installed XP CD, if you downloaded SP2 then you need an SP1 XP CD

Click start then run, type chkdsk /f /r then press enter, type Y to confirm for next boot, press enter then reboot.

Windows will appear to load normally then either the monitor will show progress or the screen will go blank, do not disturb this.

This will take an hour or so before it gets to the desktop.

Download and install Tune Up 2006 Trial

Run Tune Up Disc Clean Up

Run Tune Up Registry Clean Up

Click Optimize and Improve to run Reg Defrag, which will take a few minutes and need a reboot. You should disable the antivirus programme to run this and check it is running after the reboot

After the reboot, click optimize then system optimizer to optimize the computer, select computer with an internet connection from the drop down menu, this also requires a reboot

After the reboot, click optimize then system optimizer to accelerate downloads, select the speed just above your actual connection speed, this requires a reboot

After the reboot, click optimize then system optimizer to run system advisor



If no change

You can use this guide to repair XP

Possibly, you will need to press the start button and keep tapping the delete key, (possibly F2) until the PC enters set up. Change the boot order to CD ROM Drive then hard drive, press F10 then press enter, load the XP CD then type Y then press enter, as it reboots, look for press any key to load from CD, press enter

You will need the XP product key to complete this

If you have audio / video files which are subject to DRM you should check with the provider for known issues with performing an XP repair install


XP Repair Install

Windows XP repair feature won't delete your data, installed programs, personal information, or settings. It just repairs the operating system

After running XP Repair you will need to install all Windows Updates

Microsoft Update

I dont understand what you mean by change or no change.
Also, this will leave all files on the PC intact, correct? Its not like re-formatting where it deletes all of the files?

Run through it from here

Click start then run

If you do not see any change / improvement, run the repair, which will leave data and programmes intact

Note the bit about DRM Files
