Windows 7: Deleting SP1 Backup files

Deleting SP1 Backup files

After installing SP1 I noticed a drop in hard drive space. I found that 920M's was being used for backup files to W7.

I have the option to delete the 920M's but the systems says once deleted I will not be able to uninstall SP1 if I ever needed to do so.

My question is why would I need to uninstall SP1 and should I keep the files. I have enough hard drive space not to matter but I would prefer to have the free space.

At this point I think it is safe to delete them if you have seen no issues or oddities since your upgrade to SP1. I have removed mine. I am sure some of the guru's here can chime in also.

If you have been reading this forum and others, you would know that win7 SP1 appears to be somewhat buggy. Different people have had different experiences but personally, I've never seen so many complaints about installation errors and post-install annoyances with any other SP. So in case SP1 breaks something critical, one might want to remove it.

Since you have plenty of hard disk space, I suggest you retain the backup files till you're confident SP1 is stable on your system.

Personally I would keep the setup/uninstall files this is because the day after I installed SP1 I found one of my most precious tools (remote administration software) was not installed yet and does not support being installed on SP1. So I had to downgrade to No-SP. If you feel like you are 100% confident that all of your programs are working properly and will not have some random error caused by sp1 the day after you remove those files, I would say if you wanted the space go for it.

From reading the forums, and from being one of the folks that had issues installing it, I am seeing quite a few issues installing, but not a lot of issues after. Most post install issues are driver related (which should have been taken care of prior to install) and incompatible registry tweaks. I saw one where a user was having an issue related to boot times.

Again, if you are seeing no issues with your system and you need disk space or just want to recover the space, it should be safe to remove those files. Be sure that there are no oddities or issues before you do though. If your system is running fine, remove them.

I slipstreamed SP1 using my original Windows 7 DVD, and did an in place repair install from inside Windows 7. I had a lot of issues PRE install so the service pack would not install. The post issues was my fault for not properly upgrading my video drivers. If you hare having no issues, you can safely remove them.

Did I mention that you should take a look around and be sure you are having no issues before removing them?

So the thought that SP1 was just a rollup of the previous updates and hotfixes is not quite true then?

Also the statement about reliability issues being addressed actually means that pre SP1 it was too reliable so we've 'fixed that'
