I bought this computer about three years ago and at that time its components were about a year out of date. I bought it with Win7 pro installed as I was advised to steer away from Win 10. I use a registry repair tool which I run about once a month. Recently the computer began behaving oddly, mainly loading programs slowly or not at all. Then I remembered that I hadn't run disc cleanup in a long time. Well I started running the program and it took a while for it to compile how much disc space needed cleaning, over 700 gigabytes. After running the disc cleaner twice and my registry cleaner again my computer seems healthy again.

What I don't understand is (a) how did my hard disc get so full and (b) why does my registry checker alway find between 50 and 100 problems to fix after waiting only a week between checks. Why does the Windows OS generate so many errors and create so many junk files.

Depends on what software you have on it, and what the settings are- i've never had that occur on any of my systems, and I never use any 3rd party disk clean-up programmes.
Once I've got the system working, and maybe a couple of months after a major OS update i'll run the Windows disk clean-up tools to free up space from the update installation files, but that's it. So, maybe twice a year.

(b) why does my registry checker alway find between 50 and 100 problems to fix after waiting only a week between checks.

Because it's a scam. Seriously.
All the 3rd party registry checkers & file update checkers & driver checkers are nothing but pure, unmitigated, crapware- they serve no useful purpose.
And one of the few clean-up tools that was actually useful (CCleaner) is now unfortunately little more than crapware itself.

I run Microsoft Security Essentials on My Win 7 Pro x64 PC as My anti virus program, once a week My PC also runs Hitman Pro v3.7.12 build 253 64bit for Malware, I don't know what is happening to your PC, but this will probably help. Good luck & Happy New Year.

And I never worry about the registry, though I do know My way around it, those who aren't familiar should not go in there as one small mistake and your OS might need to be repaired.

Grant is correct. My guess is the registry cleaner is introducing those errors. Likely it is "fixing" something that isn't broken and when you run the program it detects the "fix" and has to repair it back to correct. Next time you run the cleaner, bam, it unfixes the correct values.

As to the windoze cleanup, likely all those registry fixes and unfixes had piled up and they needed to be deleted. I know as Grant says, on my systems I simply don't have anything it finds unless it is an update file that didn't delete after it was installed and of course the browser caches.

One of the easiest fixes is cleaning out one directory: c/windows/temp.
