Suddenly, some of the applications on my computer have lost ability to write to disk:
- MS Paint cannot save file in PNG or JPG format, but can save BMP
- MS Word cannot save a file
- MS Word cannot open DOC files (as that requires creation of lock file) but can open DOCX files
- Eclipse cannot install plugin downloaded from web
Other apps I have tried so far work fine. The ones which do not work do not work even with flash drive. It kind of looks like some permission problems.
I may have messed something in registries as I have been developing a script which modifies environmental variables system wide, but it can be completely unrelated. Any ideas what may have happened?
