I am facing issues with a family members PC which is running Windows Vista which has been running very slowly for quite some time now. I have used Tweaking.com Windows Repair 3.8.2 which has not resolved the issue. Whilst running the repairs I noticed there are many messages stating along the lines of could not find file/registry file and there are many errors, is there a way which I can get the missing files and registry files back? I have tried system restore and I am unable to perform a repair install or fresh install as I don't have all the software which will need to be reinstalled. Some help would be highly appreciated. Thanks.
