I have a problem with my Windows 7 computer. I installed a modified version of Windows 7 Ultimate 32-bit called Tiny7 (search it on Google). which is basically a version of Windows stripped down of unnecessary features in order to keep it lightweight for older computers. I decided to install this on my old XP desktop. It works well, until I discover that certain features don't work. The first one is the Troubleshooting section. Every time I try to go to fix a problem it shows this: I decided to search Google to see if I could get said copy of that file to see if I could fix the issue manually. But unfortunately the results I got were basically spamware. If I did copy a "msdt.exe" over from someone giving me a copy of theirs or so, would it work? The next problem is with System Restore. If I wanted to create a restore point should I need to fix my computer, it comes up with this: This one is less detailed, so really, I can't give any information on this one, nor have I tried anything. I did various other troubleshooting options to fix the issues. I booted into Safe Mode, went to command prompt, did "sfc /scannow" and it came back saying there were corrupted files, but Windows could not repair them. Of course, this is what I should expect from a slimmed down, modifed version of Windows, but I would really appreciate some troubleshooting advice. Thanks!
