It all adds up to… there just isn’t a time when the registry is sat there quietly twiddling its thumbs thinking “I’m bored”. Then there’s changes made to ‘permissions management’ which all takes time to process and record (especially as more ‘Security’ sub-keys get added ). There’s just bucketloads of new categories in both system and user hives. The amount of information recorded in the registry has expanded exponentially, some of it to do with cloud-based content and default apps running in the background, all recorded faithfully in the registry (see CloudStore, ContentDeliveryManager and BackgroundAccessApplications under HKEY_CURRENT_USER as examples). Where once a simple change might have resulted in a binary flip from 0 to 1 (or vice versa) to reflect a simple change state from OFF to ON (or back again), the registry now records *much* more (and the entries and data are increasingly more obfuscated ). Back in Win 7 days you could reasonably expect to find your own user settings stored somewhere in HKEY_CURRENT_USER\Software\Microsoft\CurrentVersion and it was fairly simple. Process Monitor shows that a change which theoretically should only affect the current user now also generates copious system-wide activity… and vice versa. Windows 8 changed that and these days that hive separation seems to have disappeared completely. (Although file read/writes would often wait for user idle times before flushing to disk.)įor example, data changes within the Windows 7 registry tended to be *either* system-wide (HKEY_LOCAL_MACHINE) *or* per user (HKEY_CURRENT_USER) but not usually both. IMO previous versions of Windows were just a tad more restrained about registry activity and tended to react specifically to user actions rather than just read/write continously. If you look at Windows 10 registry (and file) read/writes using Process Monitor you’ll see almost continuous data events. Here’s a few reasons based on my own observations using the Registry Editor and TechNet/Sysinternal‘s Process Monitor over many years: A question was asked in another thread about why registry cleaners were especially bad with Windows 10.
