Hi
I'm trying to make some changes to my sister's one-year old computer (preinstalled WXP SP2) and things have just gone from bad to worse.
1. I installed McAfee Internet Security Suite 2007 to replace the trial version of McAfee software that came preinstalled.
2. I uninstalled Microsoft Office 2003 trial version that came preinstalled and installed selected parts of Office 2000 that she wanted.
3. I installed a USB slide/filmstrip scanner which conflicts with the existing USB flatbed scanner resulting in both not working.
4. I installed a firewire PCI card, and replaced a DVD-RW that failed yesterday.

The system has slowed to a crawl - doing a shutdown/restart now takes a full 10 minutes.

I have lots of restore points to choose from:
May 1 - System Checkpoint
May 2 - System Checkpoint
May 3 - System Checkpoint
May 4 - System Checkpoint
May 6 - Software Distribution Service 2.0 (Is this what shows up for Windows Automatic Updates?)
May 10 - System Checkpoint (This may be the last restore point prior to installing McAfee, since it was purchased May 10)
May 11 - two instances of Software Distribution Service 2.0
May 12 - Software Distribution Service 2.0
May 13 - Six entries mostly associated with replacing Office 2003 trial with Office 2000 stuff, and installing the slide/filmstrip scanner.

Questions:
1) What is a good strategy for deciding which checkpoint to try first?
2) If I don't try the oldest checkpoint (May 1) first, is it likely to be deleted by the system as I try other checkpoints?
3) Is it a good idea to just start at the most recent and work backward until the system works better?
4) If I choose the May 4 restore point and like it, can I delete all the May 13 checkpoints as a way to regain free disk space so that my May 1 to May 4 restore points will be retained longer?
5) Is there some way to mark a known good restore point so it will be retained essentially forever?

Does anyone have any URLs to share on choosing and using restore points?

Paul, it's best to first uninstall any software and hardware (including removing drivers) that was added after the restore point you intend to go back to before doing the system restore. Otherwise that could lead to more inconsistencies. System restore does not monitor all files from a particular software installation, just certain monitored file types. Only using system restore without first uninstalling the software will remove the monitored files, but not the others.

For undoing driver updates use the driver rollback feature in device manager.

If you have nothing else to go on, I suggest you start with the most recent changes and work your way back.

Note: restore points that relate to software distribution service are automatic restore points created by windows update prior to installing an update (or group of updates if more than one is done at a given session). It's best to first remove what updates you can through Add/Remove programs before using that particular restore point.

Personally I would not use McAfee or Norton for security products. They are resource heavy and can be problematic, either sooner or later. There are good alternatives that are much less resource heavy, and in some cases free. For AV there is Avast (my preference) and AVG, both free, or NOD32 and Kaspersky for paid versions.

For firewalls there is Sunbelt Software's Kerio Personal firewall (free and paid versions), and Comodo personal firewall.

For Anti-Spyware there is Windows Defender, Ad-Aware SE (new version coming soon), SpyBot S&D, and SpywareBlaster - all free. Another good program, I have heard but not tried, is AVG anti-spyware (formerly Ewido).

Note: when building a system, make one change at a time and test. Fix any problems that are found before adding more changes to the mix. I like to use a drive imaging program to image the system to an external hard drive. Image before making a significant change, make the change, test, if all is well, image, make the next change etc. In the long run it save you much headache.

I currently use Acronis True Image Home version 10 for this. You can put together a 320 GB external drive set up using a bare drive and an external drive enclosure for under $100 at places like Newegg.com. This is an excellent backup/recovery solution for the long term. Regularly image the system and keep several iterations of images. Restores can be done on a file, partition or drive basis. The initial image must be a full image, but subsequent images can be differential or incremental, saving much time and space. For example on one particular system, the full, compressed image including the system and all data drives consumes about 62GB and takes about 3 1/2 hours to do including a full verification. An incremental image after that, done on a daily basis takes less than 10 minute (without verification). The size depends on how many changes were made that day. Anywhere from 1/2 GB to 5 GB. When building a system, the size of the image will be much less, you aren't imaging data. Taking an hour or less to do the first full image, then 5 minutes or so to make an incremental image in between making changes is time well spent.

No, you cannot delete selective restore points or save one forever. All restore points are chained together. If the chain is broken it won't work.

The maximum time for retention of restore points is 90 days but it is not functionally useful restoring back more than a week or two at the most. Too many restore points increases the chances of corruption in one of them which renders all of them useless. There are 3 ways to control restore points:

1. Turn off system restore. Then turn it back on. This will remove all restore points.
2. Use disk clean up. This will remove all but the latest restore point
3. Limit the size allocated to system restore. By default that's 12% of the drive. That's way too much on today's large drives. Cut it back to around 1GB or less so you keep at most two weeks of restore points.

Note: System restore is not a backup. It backs up the registry, system files and certain monitored files for apps, but it doesn't backup everything and does nothing for user data. It does not replace, and it is essential that one sets up and regularly uses a backup means. As I said before drive imaging to an external drive I an excellent solution to this.

System restore is useful but it is best used to undo a single change shortly after that change was made.
