Could you give some details here? What did you run, what OS, did Windows stop booting altogether
Win 7 - 64 - now back to Service pack 1, but before running Privazer it was up to date. OEM version that came pre-installed on my Samsung notebook.
Privazer freed up 5 GB after running it with default settings. Meanwhile, however, I got 10 GB LESS space than before running it, because Windows went crazy afterwards, trying to get all kinds of fixes, updates, whatever. Continually aborting updates because of errors.
Boot-up is no problem. Except getting errors from auto-run apps about missing services.
First 2 days after running Privazer the overall responsiveness was extremely sluggish. Jerky mouse movements, long delays between clicks, dialogs and windows building up line by line.
Which made me contact Privazer support. Their support (very commmited and friendly) resolved the sluggishness to some extent.
I still suffer from extremely slow context menus, say I right-click anything in Win Explorer - folder or file - it takes 10-20 seconds b4 the menu pops up, sometimes it does not come up at all.
Process Explorer shows a whole bunch of entries that report "error opening process". Some apps report problems upon startup. The Silent Mode of my notebook does not work anymore, the fan keeps blowing at full speed. Bunch of other problems that are less aggravating. Altogether a very uneasy feeling of working on a messed up, broken system.
